PSK/QAM/APSK Modem

KEY FEATURES
  • Modem (modulator + demodulator ) with flexible configuration:
    • Modulation: BPSK, QPSK, OQPSK, p/4 DQPSK, 8-PSK, 16QAM, 16APSK, 32APSK
      Variable data rates up to 22 Msymbols/s
      Center frequency: +/- 10 MHz
  • Modulator outputs:
    • Analog baseband differential (2 * 12-bit complex, 64 Msamples/s)
      Digital (2 * 10-bit complex, up to 90 Msamples/s)
      Digital (2 * 14-bit complex, up to 50 Msamples/s)
  • Demodulator intputs:
    • Analog baseband differential (2 * 10-bit complex, 64 Msamples/s)
      Digital (2 * 10-bit complex, up to 105 Msamples/s)
  • Modulator data I/Os:
    • Two synchronous serial interface,
      USB 1.1/2.0
      LAN/TCP-IP (COM-1203 only)
  • Extensive test & monitoring
    • BER measurement
      PRBS-11 test sequence generator
      Loopback mode
  • Synchronization sequence (unique word) insertion and detection to facilitate demodulator phase ambiguity removal
  • ComScope-enabled: key internal signals can be captured in real-time and displayed on the host computer
  • Connectorized 3"x 3" module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right, bottom). Single 5V supply with reverse voltage and overvoltage protection. Interfaces with 3.3V LVTTL logic
