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
- SOQPSK-MIL, SOQPSK-TG
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.
