 COM-1202/1203 PSK/QAM/APSK modem
This second generation modem combines several phase/amplitude modulation schemes including BPSK,QPSK,OQPSK, DQPSK, 8-PSK, 16-QAM,16-APSK and 32-APSK at speeds up to 22 MSymbols/s.
Highly integrated, it includes modulator, demodulator, bit error rate measurement, USB interface, digital and analog baseband interfaces.
Two versions are available: COM-1202 with a built-in USB 2.0 interface and COM-1203 with a built-in LAN/TCP-IP interface
As with many other ComBlock modules, the VHDL source code is also available for purchase.

 COM-8005 Signal Delay / Satellite Simulator
The COM-8005 uses its 256MB memory to delay a baseband input in real-time. Thanks to the large memory, the delay can be substantial: 2.6 seconds with 2x10-bit complex baseband signals at the maximum sampling rate of 40 MSamples/s. Of course, the delay can be even longer when decimation is used.
Ancillary functions include: DC bias removal, frequency offset, phase offset and decimation, all programmable.
The COM-8005 interfaces directly to the family of COM-300x RF, IF and baseband receivers. It also interfaces directly to many baseband, IF and RF modulator ComBlocks at its output, making it perfectly suited for satellite channel simulation.
