Product Details

The QPSK Demodulator Quad comprises four independent DVB-S receiver with loop-through inputs and
double ASI outputs (CW-487X) or IP outputs (CW-497X) by channel. The QPSK demodulator is based on „Zero IF” technology; the circuitry automatically identifies the FEC, to be entered are only needed the channel frequency and the symbol rate.  The  QPSK demodulator has no controls on its front panel, all settings and programming are made from the computer.

Main features:
•  Four QPSK demodulators (DVB-S only) with loop-through inputs for the 950 ... 2150 MHz band
•  Symbol rate between 2 MS/s and 45 MS/s, MCPC and SCPC mode
•  Computation of the C/N value in the 2 ... 18 dB range
•  Direct Conversion technology
•  Common Interface compatible 204 byte/packet format output signal (CI module under design)
•  Computer management system
•  Built-in stream analyzer and picture/sound reproduction
•  19” × 1 HU unit frame, 3.3 V supply voltage, low power consumption, continuous service
