Features www.sigtek.com 9075 Guilford Road, C-1 • Columbia, MD 21046 • 410-290-3918 • 410-290-8146 fax Soft decision bits: RS-422 and VME P2 X-Y constellation: SMA, high impedance scope INPUT OUTPUT Signals: BPSK, DBPSK, QPSK, DQPSK, FSK, and MSK Rates: PSK from 1.2 kS/s to 16 MS/s FSK from 1.2 kS/s to 500 kS/s Burst acquisition: Phase estimator assisted Carrier error tracking: 5% of symbol rate DEMODULATION 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.
