Overview
- Digital modem with flexible configuration:
- Variable data rates up to 39.5 Mbits/s
- Frequency acquisition range: +/- 20% of symbol rate with no apriori knowledge
- Selectable payload field length up to 8000 symbols/frame. A burst can comprise one or multiple frames
- Usable as continuous mode, random access burst mode, or time-division multiple access (TDMA)
- Includes convolutional (K=9, R=1/2) error correction
- Modulation: BPSK, QPSK
- Coherent demodulation for operation at low SNR
- Modulator and demodulator are independently configured
- Demodulator inputs: Digital (12-bit complex, up to 160Msamples/s)
- Modulator outputs: Digital (2 * 16-bit complex, up to 160 Msamples/s)
- Modem data I/Os: 10/100/1000 Ethernet LAN/UDP
- Frequency reference: internal TCXO or input for an external, higher-stability 10 MHz frequency reference
- Built-in tools: PRBS-11 pseudo-random test sequence, BER tester, AWGN generator, internal loopback mode, carrier frequency error measurement
- Graphical User Interface is used for remote monitoring and control over a USB or TCP link
- Interface compatible with ComBlock RF receiver, RF modulator, ADC/DACs, RF transceivers
- Interface compatibility:
