• Model: COM-1827
  • Shipping Weight: 0.5lbs


Add to Cart:
  • Modulator/demodulator for continuous-phase modulation (CPM), including
    • MSK, GMSK (BT = 0.7,0.5,0.3 and 0.25)
    • FSK, GFSK
    • PCM/FM
    These constant envelope modulations are ideal for operation through power amplifiers near saturation.
  • Flexible programmable features:
    • Symbol rate up to 39.5 Msymbols/s
    • Modulation index h [0.125 to 4]
    • Frequency pulse type (rectangular, Gaussian, raised cosine, etc)
  • Coherent demodulation for h = 0.5
  • Non-coherent demodulation for all other modulation indices h.
  • Frequency acquisition range > +/- 12% of symbol rate. Tracking symbol rates over +/- 50ppm around nominal setting.
  • Implementation loss < 0.5 dB down to Eb/No = 2dB. 4-bit soft-decision output (SOVA) for use by follow-on error correction.
  • Convolutional or Turbo-code FEC error correction
  • TCP server for modulator data input and demodulator output. UDP server for demodulator output.
  • Built-in tools: PRBS-11 pseudo-random test sequence, BER tester, AWGN generator, internal loopback mode, carrier frequency error measurement.
