Features - Demodulates BPSK, DBPSK, QPSK, DQPSK, OQPSK, MSK, and FSK - PSK symbol rates from 1.2 k S/s to 16 MS/s - FSK symbol rates from 1.2 k S/s to 500 k S/s - Phase estimator assisted TDMA burst acquisition - Tuning resolution of 1 Hz - Java TM remote control over TCP/IP interface - NT device drivers (Solaris TM drivers optional) - TDM, TDMA, Push-to-Talk, SCPC - Matched filter CDMA spread spectrum RX (opt.) - FEC decoder (opt.) Software Radio Demodulator for demodulating diverse signals A member of Filtronic Sigtek’s high performance VME software radio family, the ST-135 high performance software radio demodulates a growing set of signals including BPSK, DBPSK, QPSK, DQPSK, FSK and MSK. Bit rates from 1.2 Kbps to 32 Mbps with future growth to 40 Mbps and beyond. The expandable software radio architecture allows addition and enhancement of demodulation types. Control software includes a Java TM control application for TCP/IP remote operation and NT device drivers. Options include a direct sequence CDMA spread spectrum receiver and FEC decoder.
