The product that you bought incorporates the latest technology in data decoding together with the latest software release available at the time of shipment. Please, check our website http://www.wavecom.ch for software updates. Always check the latest documentation on the installation CD or on our website. We thank you for choosing a WAVECOM decoder and look forward to work with you in the future. This chapter introduces WAVECOM, the field of activity of the company, and how you may benefit from the expertise of WAVECOM. General Info about WAVECOM Products WAVECOM ELEKTRONIK AG develops and sells products for HF/VHF/VHF/SHF (Satellite) data monitoring. The WAVECOM products consist of hardware (for example W61PC, W61LAN) and appropriate software. If the customer orders a W61PC or W61LAN, then he automatically receives the actual software that is necessary to operate the unit. This software is an integral part of the W61PC or W61LAN and does not have to be ordered additionally. W-CODE consits only of a hardware as the sound card, a virtual audio card, a WAV file or TCP/IP is used for data input. The list of codes and functions can be found on our web http://www.wavecom.ch/HTML/specs.htm. The specifications comply with the up-to-date software. The SAT and CODAN options are available to authority / government customer only. If an order is placed from an authority / government customer we do need a signed End User Certificate (EUC). Options At present the following options are available: In the manual, options are marked with (Option). 1. W61SAT (INMARSAT) (government customer only.) 2. W61CL (Classifier) 3. W61PACTOR3 4. W61CLOVER2 5. W61CLOVER2000 6. CODAN9001 (government customer only.) Options for W61PC and W61LAN Options 1 and 2 relate to the serial number of the hardware (W61PC, W61LAN). If a customer orders one or several of these options, the activation of the functions is done with a corresponding activation key that is enclosed with the software delivered. The activation key to activate the option/s relates to the serial number of the hardware. This means that any option works only with the hardware for which serial number the key was generated. The key is non-negotiable to other hardware (serial number)! Options 3, 4, and 5 do NOT relate to the serial number of the hardware (W61PC, W61LAN). The delivery occurs on a USB dongle with a key file for activation. Prerequisite: The W61PC/LAN hardware must have the actual software version 6.4.00 or later! Older software versions can be updated (see price list on www.wavecom.ch). Manual V6.6.5.0 WAVECOM Decoder Welcome 1 Options for W-CODE Options 1 and 2 are controlled from our CmStick. If a customer orders one or several of these options, the activation of the functions is done with a corresponding activation file has to be loaded into the CmStick. Options 3, 4, and 5 do NOT relate to the serial number of the hardware (W61PC, W61LAN). The delivery occurs on a USB dongle with a key file for activation. Training WAVECOM offers to all our customers a complete, professional training program covering all the key features of our products. Depending on your skills (if you are an expert or a beginner), together we will work out a special training program for you. General information in radio data transmission, frequency monitoring and associated topics like basic signal processing and recording methods can also be included in a course. To safe time, some signals for the training will be played back from hard disk. But also live signals are used for decoding. Training is available on your location or in Switzerland. W-BV BitView Tool The splendid BitView Tool (W61BV) is an external .NET application to analyze unknown signals. It is possible to import the data stream directly from the W61PC decoder or to import data files. Offline tool, stand alone application. Bit manipulation tools. Bit display tools (text, graphics). Multiple analyses may be processed at the same time. Auto-update functionality. Report generator (parameter, data; ASCII, XML). Free drag and drop of functions. Re-arrange functions in tree view. Nested docking. Auto hide. Free drag and drop of windows. Apply and modify alphabets. Persistent to XML file. The application can restore its screen layout every time it starts up. NET technology No installation required, just run the executable. Data import from W61PC/LAN and new WAVECOM® products. Custom defined functions. Reports in text or XML format. MatLab and C# user defined functions. Source Code Source code is available for professional users. Please, inquire to receive an offer from WAVECOM, if you plan to add your own modes.

W-CODE Server Control The WAVECOM Server and the WAVECOM Server Control applications are used to setup and to monitor the connections between devices (clients) and server, respectively. The server is responsible for managing the devices in the computer as well as all the connections made to those devoces. The WAVECOM Server is started by the GUI for a local connection (GUI and devices on the same machine) or by the Server Control for a remote connection. The WAVECOM Server is started as a Service. W-CODE Device Serial Number The serial number of the device is build from a part on the active MAC address and a counter. It can be checked in the "W-CODE Device" screen for all available units. The same number is used as a reference for custom inputs and default settings. You will lose some settings if you switch to a different LAN adaptor (switching from WLAN to LAN). W-CODE Hardware Installation Apart from a Windows PC and a software protection hardware, no additional hardware is required for decoding. CmStick A software protection hardware has to be connected to the computer. The hardware device used for the software protection is called the CmStick and is available as: a small USB device a PC Card (CmCard/M, Cardbus, 32 Bit) a Express Card|34 (CmCard/E) The W-CODE service will not start an specific options of the software will be disabled if the respective valid licenses are not found on a CmStick connected to the system. Manual V6.6.5.0 WAVECOM Decoder Products 7 After the installation of the software on the computer, the icon will be presented in the tray icon area. Note: when a CmStick is plugged into an USB socket of a LCD, the CmStick will no longer be detected by the software protection server if the monitor is switched off. Hence a running application relying on the licenses stored on such a CmStick will stop working or disable its features. W-CODE Licensing Additional options to the basic W-CODE software are available from WAVECOM. By default, W-CODE is licensed with an update period of 12 months. It is possible to orderd an extension for the update period by another 12 months.

W61PC The powerful W61PC hardware includes a digital signal processor (DSP) and a fast 14-Bit A/D converter. Four signal inputs are available: AFIF#1-3, IF70MHz, and DIG/EXTDEM. An extremely stable direct digital down-converter (DDC) translates all input signals to base band. The DSP demodulate the incoming data while the PC CPU provides the decoding and display of the data. Manual V6.6.5.0 WAVECOM Decoder Products 9 One PC can accommodate a maximum of eight W61PC cards. WAVECOM recommends that the number of cards installed in a standard PC does not exceed four. Plug-and-Play (PnP) Automatic installation is presently available. W61PC Hardware Installation Before unpacking the W61PC card or installing it in your PC ensure that your body is grounded to avoid damaging static sensitive components on the card or in the computer. You can reduce static electricity on your body by touching the metal chassis of your computer or using a standard ground wrist strap. Power off your computer, unplug it from its power source and disconnect all peripherals. Then carefully remove the cover of the computer, and locate a free PCI slot. Carefully insert the card into the connector and check that it is fully inserted. Replace the computer cover, and power on the machine.

However, a start of a transmission mode is not possible without decoder hardware. W61PC Drivers and Windows Logo Testing Windows 2000/XP introduced a new feature called Driver Signing, in which drivers are certified by Microsoft Logo testing program and a digital signature added to inform the operating system of this. As WAVECOM drivers are only used in a small number of computers, they are not submitted to Microsoft for certification. As a result, during driver installation, a dialog box will be displayed to inform the user that the driver is not signed. This message does not indicate that a problem exists with the driver. It is purely an informational message to notify the user that the driver does not contain a digital signature. To complete the driver installation, users should select the Continue Anyway button. W61PC Server Control The WAVECOM Server and the WAVECOM Server Control applications are used to setup and monitor the connections between decoder cards (clients) and the server. The server is responsible for managing the decoders connected to the computer as well as all the connections made to that decoder. The WAVECOM Server is started by the GUI for a local connection (GUI and card on the same machine) or by the Server Control for a remote connection. The WAVECOM Server is started as a Service. W61PC Licensing Software Updates An initial 12 months software update contract is included in the price of the device. A software or hardware key is required to activate the updates, and to get the key, you have to register at WAVECOM via fax or the internet (see "Registration Form on page 242"). If the device was ordered directly from WAVECOM, the key is automatically provided to government bodies. Software Options Additional functions e.g. Classifier Satellite Modes PACTOR-III, CLOVER-2, CLOVER-2000 (licensed with an additional USB-Key) may be enabled and licensed to work with your decoder. Products 13 Manual V6.6.5.0 WAVECOM Decoder In the manual, options are marked with "Option". Follow this procedure to order options: Serial number of the card or device.

Press the Edit button to add or modify a key: 14 Products Manual V6.6.5.0 WAVECOM Decoder Enter or Change a License File (PACTOR-III, CLOVER-2000, CLOVER-2) As an option, the following modes can be purchased: PACTOR-III; Clover-2; Clover-2000 CODAN9001. In order to run the purchased optional modes, a license is required for each mode. The license for a certain optional mode consists of two parts: A FLEXid USB dongle with a specific dongle ID and a specific FLEXid number. Mode-specific entries in the plain-text license file named "medav.lic". Such an entry specifies a unique key string as well as the FLEXid (identified through its specific number) with which the mode is associated. Hence, to enable an optional mode on the personal computer (PC) where the decoder us running, the license file "medav.lic" has to be located in the installation directory of the W61PC software, and the associated dongle needs to be inserted into a USB socket of the same PC. This document gives some information on the license system and describes the installation steps to be taken in order to enable an optional mode in the WAVECOM decoder. Preliminary Step Before proceeding with the installation of the license file for the optional modes, a professional version of release V6.4.00 (or newer) has to be installed on the PC where the respective decoder hardware resides. USB Dongle The FLEXid USB dongle is one part of the licensing system for an optional mode. Such a dongle is identified by a dongle ID and a FLEXid number beginning with 9 (e.g. 9-75C373D3). An optional mode is associated with a specific FLEXid USB dongle, as denoted in the specific entry in the license file "medav.lic". Hence, it is possible that different optional modes are associated with different FLEXid USB dongles. However, there will be only one "medav.lic" file. In order to have the FLEXid USB dongle fulfill its purpose when it is inserted into a USB socket of the PC where the decoder runs, the USB controller must be enabled on that PC. The USB controller can be activated in the PCs BIOS menu, to which you can access at PC start-up by pressing a specific function key (typically, F2). The required drivers for the operation of the FLEXid USB dongle are installed together with the professional version of the release V6.4.00 (or newer). The first time you insert the USB dongle into a specific USB slot on the PC in which the decoder runs, you are notified by the system that it has detected a new hardware device (i.e., the USB dongle). The necessary HASP/Aladdin drivers should be automatically set up, and the USB dongle is then ready to operate when its red light-emitting diode (LED) is illuminated. License File The provided compact disc (CD) contains the license file "medav.lic", which is one part of the license system to which the purchased optional modes are subject. An example of a license file for the optional modes Clover-2, Clover-2000, and PACTOR-III is shown below: SERVER any 012345678901 Manual V6.6.5.0 WAVECOM Decoder Products 15 VENDOR medav FEATURE Clover2Demod medav 1.0 31-dec-2004 25 \ HOSTID=FLEXID=9-12345678 SIGN=" ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD EF01 2345 6789 ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD" FEATURE Clover2Demod_DECODEDDATA medav 1.0 31-dec-2004 25 \ HOSTID=FLEXID=9-12345678 SIGN="EF01 2345 6789 ABCD EF01 ABCD \ 2345 6789 ABCD EF01 2345 6789 ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD" FEATURE Clover2000Demod medav 1.0 permanent 1 \ HOSTID=FLEXID=9-12345678 SIGN="2345 6789 ABCD EF01 ABCD EF01 \ 2345 6789 ABCD EF01 2345 6789 ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD" FEATURE Clover2000Demod_DECODEDDATA medav 1.0 permanent 1 \ HOSTID=FLEXID=9-12345678 SIGN="6789 ABCD EF01 ABCD EF01 2345 \ 2345 6789 ABCD EF01 2345 6789 ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD" FEATURE PactorIIIDemod medav 1.0 31-dec-2005 uncounted \ HOSTID=FLEXID=9-12345678 SIGN="DCBA EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD EF01 2345 6789 ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD" FEATURE PactorIIIDemod_DECODEDDATA medav 1.0 31-dec-2005 uncounted \ HOSTID=FLEXID=9-12345678 SIGN="10FE 2345 6789 ABCD EF01 ABCD \ 2345 6789 ABCD EF01 2345 6789 ABCD EF01 2345 6789 ABCD EF01 \ 2345 6789 ABCD" At the beginning of the license file, a SERVER entry is to be found in which the license server (host name and MAC-address) is specified. Since in this case no license server is used, the specified host name and MAC-address are dummy values. The next entry (VENDOR) denotes the vendor of the license. Then, depending on the purchased optional modes, a different number of FEATURE entries may follow. The structure of such a FEATURE entry is as follows: name of the module; name of the vendor; version number of the module; date of license expiry ("permanent" if the license duration is unlimited); maximum number of concurrently active modules ("uncounted" if there is no limitation); "HOSTID=FLEXID=" followed by the number of the FLEXid that is associated with the respective module; "SIGN=" followed by a specific key string. Note that, for the optional modes Clover-2, Clover-2000, and PACTOR-III, two FEATURE entries each are present in the license file, since these modes are each split into two modules, one performing demodulation and the other decoding of the demodulated signal (e.g. Clover2000Demod and Clover2000Demod_DECODEDDATA). License File Installation The license file "medav.lic" on the provided CD has to be copied into the software installation directory C:\Program Files\WAVECOM\W[xx]. The installation directory already contains a dummy license file named "medav.lic". Hence, during the copy process, you may be asked whether you want to overwrite the existing version of "medav.lic" with the more recent and typically larger one. Answer ,,Yes so that the version from the CD is copied into C:\Program Files\WAVECOM\ W[xx]. The same procedure has to be followed also in case of a license update or update. The new license file will include the license information for the existing and for any newly-purchased optional mode. Operation The optional modes are started by selecting the respective entries in the pull-down menu ,,HF-Modes or the respective buttons in the dialog ,,Mode Selector of the decoders graphical user interface (GUI). When opening the pull-down menu ,,HF-Modes or the dialog ,,Mode Selector, a license check is performed for each optional mode. If the result of such a license check is negative, the corresponding entry or button is disabled, so that the mode cannot be selected. 16 Products Manual V6.6.5.0 WAVECOM Decoder Entries in the ,,History pull-down menu of the decoder GUI are always enabled. Therefore, if an entry corresponds to an optional mode, it will be possible to select that mode from the ,,History pull-down menu even if the USB dongle is not inserted in a USB slot of the PC. However, in such a case, the thereafter performed license check for that mode will result negative. Nevertheless the mode will be started, but no demodulation/decoding will be performed. A dialog window will pop up to notify the user of the license check failure. Hence, in order to be able to start an optional mode, the associated USB dongle needs to be inserted into a USB slot of the PC running the decoder. Removal of the USB dongle from the USB socket while an associated optional mode is running will interrupt the modes operation after a few minutes. A pop-up window will then notify the user of this fact. Re-insertion of the USB dongle will not resume the modes operation. You will have to close the optional mode, insert the USB dongle, if not already done, and restart the optional mode. Important Notes: If you accidentally delete the license file "medav.lic" on your system and, for whatever reasons, the provided CD containing the license file is lost; the latter can be replaced at no cost. However, if you lose the USB dongle, you are not entitled to a replacement of the USB dongle unless you purchase anew the concerned optional modes. Therefore, take good care of the USB dongle.

A full window is shown in this section. This is the window you will see after setup has been completed as described in the preceding paragraphs. The WINDOWS elements SYSTEM TOOLBAR, DECODER TOOLBAR, LEVEL INDICATOR and SPECTRUM INDICATOR may be moved anywhere in the screen as required. In the View menu the user may select or deselect all window elements. After installation has completed all elements are visible. Please, be aware that the appearance of the GUI will vary depending on software versions and hardware models. Main Menu The main menu includes all submenus relating to operating modes as well as analysis and set-up functions. The WINDOWS operating system is based on a multitasking kernel and can handle more than one task concurrently, and therefore the control of and interaction with the menu system will not interrupt the execution of an active function. This allows for example the shift and center frequency to be set in the Demodulator submenu without interference to or disruption of the currently active operating mode. Main Menu Screen Display This window is displayed as long as a mode is not started. Manual V6.6.5.0 WAVECOM Decoder Graphical User Interface (GUI) 23 Menu Bar As a standard WINDOWS procedure a left-click on a menu item will display the corresponding drop-down menu. File Menu The functions of the Files, View and Window menus are general system functions in accordance with the WINDOWS standard. Using the Files menu, files may be saved and opened. In addition printing, preview and printer setup is available. Save As Bitstream... allows the user to save a bit stream e.g. from an auto-correlation session as a text file of ASCII 0s and 1s. Save Selection as... allows the user to mark a screen area of text and save it to a text file. Recent History displays a list of recently opened files. For context sensitive help on a menu item, use F1 on the item. Note: Files that are saved with Save and Save as... are stored in the new WAVECOM *.WDA format. This format is used to save decoded text together with time stamps in a text file. The import of old *.W40 (W40PC), *.W41 (W41PC) and *.W51 (W51PC) files is also supported. 24 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder HF-Modes The various groups of modes are displayed in the HF-Modes and in the VHF/UHF-Modes menus. To select the modes of a group, left-click or let the mouse rest briefly on the group item to be selected. Now, the modes of the group are displayed in a separate menu. Start decoding the desired mode by another left-click. It may be difficult to guess or remember to which group a particular mode belongs. To facilitate an overview a full-screen menu may be opened by clicking the menu item Mode Selector. To start a mode, click on the appropriate menu field. Leaving the full-screen menu will not terminate an active mode. The various analysis tools are displayed in the Modes/Analysis INDIRECT and DIRECT menus. HF-Modes/Analysis and in the VHF/UHF- The descriptions of the operating modes in a separate section of this manual are arranged in alphabetical order. The Mode Selector is also available from the HF-Modes menu and from the VHF/UHF-Modes menu when clicking on Mode Selector. HF-Modes are organized as follows: Analysis Modes in the HF Menu FSK Modes in the HF Menu Manual V6.6.5.0 WAVECOM Decoder Graphical User Interface (GUI) 25 MFSK Modes in the HF Menu PSK Modes in the HF Menu MIL-STANAG and HF-ACARS Modes in the HF Menu Graphic Modes and CW in the HF Menu 26 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder SELCAL and Others Mode Selector... See "Mode Selector on page 49". VHF-UHF Modes INDIRECT Modes in the VHF/UHF Menu INDIRECT modes require additional AM or FM demodulation in the receiver, if the receiver is connected to the W61PC AF input. If the signal is demodulated from an IF signal (translation frequency <> 0), then a standard AM or FM software demodulator is automatically added to the W61 signal processing path.

In addition to baud rate, the options and values for mode, shift, center frequency, translation frequency, input and input gain may be manually entered. The availability of the functions depends on the active mode. For context sensitive help on a menu item, use F1 on the item. 28 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder Auto Click on the Auto button to enable a mode. Shift, center frequency and baud rate is automatically calculated and adjusted. The new value is selected by double-clicking on the preset value or by clicking OK. Mode... In the Mode menu the demodulator mode may be selected. Most HF-VHF-UHF modes feature a pre-selected demodulator mode for optimum performance. Demodulator Modes AM Satellite weather charts are transmitted using AM. This demodulator uses the quadrature I/Q demodulation method. The magnitude of the level indication corresponds to the AM modulation depth of the signal. The gain and the amplitude offset may be set using the Demodulator menu. BPSK BPSK shifts the carrier phase ±180 degrees. For carrier recovery a Costas loop is used. The Costas loop is a PLL with a special phase comparator, which removes the payload data from the PLL loop. The input signal is then down-converted to base band by mixing the carrier in a complex mixer, and the resulting signal is the data signal. BPSK is almost exclusively used for satellite data links. BR6028 BR6028 is a commonly found VFT (voice frequency telegraph) frequency and time diversity modem system using 7 data channels. It is sometimes also known as BARRIE. Theoretically the system may handle up to a 3 second channel dropout before errors occur. An unmodulated pilot tone is transmitted at 560 Hz. Center (Hz) Pilot Tone CH1 CH2 CH3 CH4 CH5 CH6 CH7 560 850 1190 1530 1870 2210 2550 2890 765 1105 1445 1785 2125 2465 2805 935 1275 1615 1955 2295 2635 2975 Space (Hz) Mark (Hz) Channel spacing: 340 Hz Shift: 170 Hz Channels are delayed by a multiple of 1.024 seconds. Speed: 45-100 Baud Modes: Baudot, ASCII, and some FEC modes CW The CW demodulator utilizes a steep, adaptive band pass filter and automatic amplitude control. The AGC attack time may be adjusted according to the propagation conditions. The filter response may be set to Slow, Normal or Fast. This demodulator produces high quality CW decoding. It is important to select the appropriate receiver AGC response (normal or slow). DSP The DSP mode utilizes an I/Q demodulator (Hilbert transformation). The received signal is split into an inphase component and a quadrature component. Next amplitude normalization takes place and the resul- Manual V6.6.5.0 WAVECOM Decoder Graphical User Interface (GUI) 29 tant signal is used for the frequency conversion. This method is characterized by a linear relationship between the received frequency and the output voltage of the demodulator. The DSP demodulator has a good signal-to-noise ratio and yields very good results under most conditions. DPSK In differential PSK the absolute carrier phase cannot be used for data recovery as is the case with BPSK and QPSK. To decode multiphase DPSK (up to 16DPSK) the input signal is mixed with a complex, phase regulated reference signal. The resulting data reduced signal is then filtered in a low pass filter. The following phase comparator calculates the phase difference between the signal from the integrator and the delayed signal. DPSK is almost exclusively used when phase modulation is employed on short wave data links. DBPSK Similar to DPSK, but has two phase shifts at ± 180 degrees. DQPSK Similar to DPSK, but has four phase shifts at ± 90 and ± 180 degrees. DTMF This demodulator handles multi-frequency signals. Filters are switched in on the various frequencies of the signal and the amplitude is then calculated for each frequency. Next the amplitudes are evaluated. Two simultaneous tones are demodulated. The SNR is the same as for the mark-space demodulator. DXPSK Adaptive DPSK demodulator for PACTOR-II. This demodulator will automatically adapt itself to DBPSK, DQPSK, D8PSK or D16PSK. D8PSK Similar to DPSK, but has eight phase shifts at ±45, ±90, ±135 and ± 180 degrees. D16PSK Similar to DPSK, but has sixteen phase shifts at ±22.5, ±45, ±67.5, ±90, ±112.5, ±135, ±157.5 and ±180 degrees. FFSK and GFSK Depending on the mode, the FFSK (Fast Frequency Shift Keying) and GFSK (Gaussian Frequency Shift Keying) demodulator is automatically selected. Basically this demodulator utilizes the I/Q principle (Hilbert). However, filters are adjusted to accommodate the special demands of these modes. MFSK This demodulator handles multi-frequency signals. Filters are switched in on the various frequencies of the signal and the amplitude is then calculated for each frequency. Next the amplitudes are evaluated. Depending on the number of tones used, the filters are configured as phase linear FIR filters or as IIR filters. The SNR is the same as for the mark-space demodulator. Concurrent multi-tone decoding (e.g. DTMF) is not possible with this demodulator. MS (Mark-Space) The mark-space demodulator processes the two keying frequencies of a FSK signal. These are fed to two phase linear FIR filters and the amplitude is then calculated. The mark-space demodulator exhibits an extremely good noise distance and should be used for all FSK modes utilizing a speed of less than 300 Baud. OQPSK Carrier recovery is mandatory to demodulate OQPSK. As OQPSK has phase shifts at ±90 degrees, the signal must be squared two times to produce a carrier at four times the original frequency. A PLL recovers the carrier in frequency and phase with ambiguities at ±90 and ±180 degrees. A complex mixer down converts the signal to base band and the resulting signal is the data signal. In contrast to QPSK, OQPSK has only phase steps of ±90 degrees in one step. First the in-phase part is switched, then after half a 30 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder symbol duration the quadrature part is switched. The advantage of this process is a smaller amplitude variation. OQPSK is almost exclusively used for satellite data links. QPSK Carrier recovery is mandatory to demodulate QPSK. As QPSK has phase shifts at ±90 and ±180 degrees the signal must be squared two times to produce a carrier at four times the original frequency. A PLL recovers the carrier in frequency and phase with ambiguities at ±90 and ±180 degrees. A complex mixer down converts the signal to base band, and the resulting signal is the data signal. QPSK is almost exclusively used for satellite data links. SRC The Sampling Rate Converter is used for very complex modes like MIL, STANAG or HF-ACARS requiring an adaptive equalizer. To get optimum results, this equalizer works with a sampling rate that is a multiple of the baud rate. SUBTONE Same as DSP, but the parameters are optimized for low frequencies. PB Center... Click on the PB Center menu item to adjust the center frequency of the pass band filter. See "PB Bandwidth... on page 31". PB Bandwidth... Click on the PB Bandwidth menu item to adjust the bandwidth of the pass band filter. PB (Pass Band Filter Support) Perfect signal processing (filtering) is relevant for best decoding results. Best results are achieved by using the correct filters in the receiver. This avoids blocking effects from strong nearby signals. But sometimes such correct processed signals are not available (recorded signals, large bandwidths when working with classifier). Hence additional pass band filters were added to support the operator. This makes it possible to separate different signals available in the analyzed spectrum. The WAVECOM GUI shows the PB Tuning bar below the Tuning FFT. If no tuning FFT is available (MILSTANAG, VHF-DIR etc) the parameters can be set in the Demodulator Menu. For many modes the parameters PB Center, PB Bandwidth and Center can be controlled individually (see table below). The PB parameters can be set to maximum bandwidth (switched off) with the Maximize Pass band button: Item DSP AM CW GFSK FFSK MARK-SPACE MFSK DTMF BR6028 BPSK QPSK OQPSK PB Conf. + + + + + + + + Remarks Free configuration Free configuration Free configuration Center controlled from translation freq.

PB Tuning The easiest way is to use tuning FFT to adjust e the pass white bar in the gray field below the FFT (dragging the PB center, upper or lower border). The FSK tuning picture below shows how PB center and center frequency can be set individually. The next picture shows you a tuned PSK signal. The bandwidth was automatically set according to the speed. In this mode the PB center and Center cannot be set individually. 32 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder Center... Click on the Center menu item to adjust the demodulator center frequency within 1 Hz accuracy. For modes utilizing direct FSK this button is not available. In this case the translation frequency is equal to the effective center frequency. Shift... Click on the Shift menu item to adjust the frequency shift within 1 Hz accuracy. In HF modes the range is 50 Hz ­ 3,500 Hz and in VHF-UHF modes using direct FSK the range is 50 Hz ­ 16,000 Hz. Baudrate... Click on the Baud rate menu item to start a mode. A new baud rate evaluation is performed with a maximum resolution of 0.0001 Baud. Depending on the mode the baud rate dialog box contains preset values, which may be directly selected. The new value is selected by double-clicking on the preset value or clicking on OK. Polarity... Click the Polarity menu item to toggle polarity between normal and inverse. Translation... Adjusting the translation frequency and the center frequency will adapt the decoder input to a receiver IF output. The minimum translation frequency resolution available with the decoder is 1 Hz. The effective center frequency is the sum of the translation frequency and the center frequency. The function is similar to the mixing of the signal frequency and BFO of a receiver. An exception is the FFSK demodulator for direct frequency modulation. In this case the indicated translation frequency is equal to the effective center frequency. An example for an HF receiver and ARQ-E mode: Receiver IF 455,000 Hz Translation 453,300 Hz Center 1700 Hz The advantage of this method is that the user only needs to know the center frequency. Another example for a VHF-UHF receiver and POCSAG mode: Receiver IF 455,000 Hz Translation 455,000 Hz Center 0 Hz In this case the translation frequency is equal to the center frequency. Input... The decoder supports a number of inputs: Manual V6.6.5.0 WAVECOM Decoder Graphical User Interface (GUI) 33 The AFIN#1 - 3 have a range of 50 Hz ­ 25 MHz. These inputs should be used when the source is an AF output (line or speaker) or an IF output of communication receivers and digital recorders The IF70#4 input has a range of 52.5 MHz - 87.5 MHz. This IF is common for satellite equipment The EXT-DEM input will accommodate voltage levels from TTL to RS-232C, [0 V, +5 V] to [-12 V, +12 V]. Use this input for input from an external demodulator The DIG input is physically the same as the EXT-DEM, but use different pins. Valid input level is 0.5 - +6.5 V. This 3-wire input is used for digital IF output from communication receivers (not yet supported). Rosetta is a user defined input. For further specifications, see Technical Date in the Appendix section of the manual. Gain... For manual gain adjustment, use the slider. The input gain adjustment range is 0 - 100 % of the nominal input sensitivity of the selected input. When the desired gain setting has been found, press OK to save the setting. The adjustment is valid only for the selected input. The gain settings of the four inputs are separately saved in the application initialization file. Gain adjustment should never turn on the red bars of the level indicator. For W61 only: Manual gain adjustment will not optimize the combined input sensitivity setting and the internal gains of the demodulator. To optimize input sensitivity and internal gain, press Autoset. This will start Automatic Level Setting (ALS), initiate the calculation of the optimized settings and display ALS running.... When the calculation has completed status will be displayed as ALS finished. Press OK to accept the result. Options Menu In the Options menu all support functions for a particular mode or functionality have been collected in such a way that it is adapted to each individual mode. The Option menu will therefore appear with different contents depending on the mode or functionality selected. The menu of the currently active mode is always displayed. 34 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder Alphabet... The Alphabet menu has options for transparent and normal output. The normal output includes fonts for e.g. Latin, Greek, Cyrillic, Hebrew, Arabic alphabets. The ASCII character sets for output in German, Bulgarian, US, Swedish, Danish-Norwegian, Chinese or other alphabets may also be selected. Skyper, an alphabet which is used in POCSAG mode in Germany, is also available. The transparent alphabet includes output of non-printable characters of a data transmission, e.g. ITA-2 control characters like Letter Shift and Figure Shift or undefined upper case characters. In normal alphabets these characters are not output. Code Statistic... See "Code Statistic on page 82". Letters/Figures... This option is only available for ITA-2 based modes. The Letters/Figures dialog box contains the options Normal, Letters Only, Figures Only and Unshift on Space (UOS). Letters and Figures designates the ITA-2 lower (letters) and upper (figures) cases. For reception under normal conditions the selection of one case or the other is controlled by the reception of the shift characters. Special alphabets, e.g. Chinese, comprise only letters so forcing a shift into lower case mode may be an advantage (Letters Only). Selecting this function may also be advantageous, when searching for a bit inversion pattern as the pattern may be more easily recognized. In weather code transmissions five figure groups are used so in this case one may force a shift into upper case (Figures Only). The Unshift on Space (UOS) function forces a shift into lower case after a space character has been received. In this manner the readability of the transmission may be enhanced under poor conditions (weak signals or interference). Compared to the Letters Only mode, UOS has the advantage, that single, upper case characters like period and comma are correctly printed. Only when receiving figure groups separated by space characters, the software will incorrectly shift to lower case. Period... From the Period menu the time unit per measurement may be selected. The lowest value is 50 ms corresponding to 20 FFTs/s. For the highest value of 10,000 ms a measurement is done once every 10 seconds. Toggle Clicking the Toggle function will immediately change the current case to the opposite case - from Letters to Figures or vice-versa. Thus an incorrect case shift caused by a character received in error may be corrected at once and the proper case reinstated. MSI MSI (Multiple Scroll Inhibit) is a function which will suppress multiple linefeeds (LF). In addition, a software generated Line Feed (LF) is inserted when a carriage return is received. Using this menu item the function may be separately toggled on and off for the video output. Using the MSI function has several advantages, e.g. when during reception disturbances a carriage return character is lost, this software prevents lines being overwritten and text to be lost. Some stations do not transmit carriage returns. The MSI function will then automatically generate the missing carriage return. To clearly divide a message into paragraphs many carriage returns are often transmitted. IAS IAS is the abbreviation for ISO-ASYNCHRONOUS and SYNCHRONOUS modes. Iso-asynchronous modes have start and stop elements like Baudot, but the code words have an integral number of elements. The Manual V6.6.5.0 WAVECOM Decoder Graphical User Interface (GUI) 35 IAS function is utilized for the extremely accurate baud rate determination of a synchronous or isoasynchronous bit stream. The automatic phase correction for the ideal bit center sampling (bit synchronism) is completely independent of the IAS function and is always active. The extremely accurate baud rate determination uses the number of necessary phase correction steps for the baud rate determination. In modes working with an interrupted data stream as PACKET-300, it may be advantageous to be able to switch off the baud rate correction to prevent drifting of the pre-selected baud rate. When the IAS function is disabled, any pre-selected variable baud rate will be treated in the same way as a fixed baud rate. In most of the VHF/UHF modes the IAS is permanently disabled. This is due to the lack of phase coherence between successive data blocks. An exact measurement of the phase shift is not possible for an extended period of time. In case of difficult HF receiving conditions (fading) enabling IAS may offer substantial advantages. The software will decrease the size of the phase correction steps in accordance with the verified, reduced phase errors, and thus prevent bit glitches and the resulting loss of synchronism. It is therefore recommended to enable IAS as a default. Tick the IAS menu item to enable IAS. Cycle... In some modes, the character repetition cycle may be manually selected. Time Stamp... Clicking Options/Time stamp offers a selection of different time zones for time stamping text output. Time stamping may also be disabled at a later time through this menu. To display the time stamp a new window is opened on the left hand side of the screen. When a text line has been displayed, date and time is displayed in this window. This function is available for all text output modes. 36 Graphical User Interface (GUI) Manual V6.6.5.0 WAVECOM Decoder Error Indication If Error Indication is switched on, then characters containing errors are marked in red color. If possible, the error correction will correct the data in error. Clear Screen This function will clear the actual screen. All data will be lost.
