ST-135

www.sigtek.com Features Demodulates BPSK, DBPSK, QPSK, DQPSK, OQPSK, MSK, and FSK PSK symbol rates from 1.2 kS/s to 16 MS/s FSK symbol rates from 1.2 kS/s to 500 kS/s Phase estimator assisted TDMA burst acquisition Tuning resolution of 1 Hz JavaTM remote control over TCP/IP interface NT device drivers (SolarisTM drivers optional) TDM, TDMA, Push-to-Talk, SCPC Matched filter CDMA spread spectrum RX (opt.) FEC decoder (opt.) ST-135 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 JavaTM control application for TCP/IP remote operation and NT device drivers. Options include a direct sequence CDMA spread spectrum receiver and FEC decoder.
