• Note: The newer COM-1402 now provides higher performance (22 MSymbols/s, 90MSamples/s) and extended functionality (more modulation schemes, ComScope, etc.)
  • BPSK/QPSK/OQPSK modulator
  • Programmable data rates up to 20 Mbps (QPSK) and 10 Mbps (BPSK) by steps of at most 3bps
  • Includes raised cosine square root filter with 20%, 25%, or 40% rolloff options
  • Differential and non-differential encoding
  • Synchronization sequence (unique word) insertion to facilitate demodulator acquisition
  • Internal generation of pseudo-random bit stream and unmodulated carrier for test purposes
  • Built-in channel impairments generation:
    • frequency offset (Doppler)
  • On-board or external clock selection
  • Single 5V supply
  • Connectorized 3”x 3” module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right, bottom). Interfaces with 5V and 3.3V logic

  • ComScope–enabled: key internal signals can be captured in real-time and displayed on a host computer
