DDC, Digital Down Converter BitView Tool...
 
The W61 decoder offers all functions required to analyze, decode, and process radio data communications in the HF, VHF, UHF and SHF range.

The W61PC is the first choice to build a cost efficient satellite monitoring system for INMARSAT.
The W61SAT modes are a software option for the professional versions of the WAVECOM® decoders. I
Additionally the W61PC has a fully tunable 70 MHz IF input for satellite monitoring (no external receivers are required).
 

• Notebook users
• Mobile units
• Units, “ready to go”
• Outdoor monitoring
• Use in vehicles like planes, ships, cars etc.
• Environments with changing users/computers.

The full support of all W61PC functions lets the W61LAN easily communicate with other applica­tions. Real DSP technology is combined with today's PC power.

Integrated into your W51PC or W51LAN, the new WAVECOM W51CL Classifier will automatically capture, identify and classify more than 130 modes, enabling the decoder to demodulate the signal quickly and accurately for signal surveillance and analysis. This automatic feature negates the need for training specially-skilled SIGINT operators to laboriously and manually analyze received signals.

Classifier and Code Check (CCC)

The WAVECOM classifier is an important analysis tool for classifying unknown signals. The purpose is to determine the modulation type, baud rate, frequency shift and bandwidth of one or more signals.
This option is only available for government bodies!

BITVIEW Offline Analysis 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.

PACTOR-III is an adaptive transmission mode that provides higher throughput and improved robustness compared to PACTOR-I and –II, both of designed for operation within a bandwidth of 500 Hz. To achieve the improved features, PACTOR-III uses up to a maximum of 18 tones spaced 120 Hz, thus occupying a maximum bandwidth of 2160 Hz. Six so-called Speed Levels (SL) are specified, which are predefined combinations of modulation type (DBPSK or DQPSK), channel coding and number of tones (2, 6, 14, 16, or 18) as well as positions of tones. For all Speed Levels, the modulation rate of each tone is 100 Baud.
 

CLOVER-2000 is an adaptive modulation system with ARQ that uses Reed-Solomon (RS) coding to achieve a remarkable performance even under worst HF propagation conditions. Data are modulated onto eight  tones spaced 250 Hz. The modulation rate of each tone is 62.5 Baud. The supported modulation techniques include binary phase-shift keying (PSK2A), quaternary PSK (PSK4A), 8-PSK (PSK8A), 16-PSK (PSK16A), binary amplitude-shift keying combined with 8-PSK (ASK2PSK8), quaternary ASK combined with 16-PSK (ASK4PSK16), and two-channel diversity binary PSK (2DPSK2A).
