QPSK Demodulator

DRS-1022

Pardis DRS-1022 is a low cost and high performance IF demodulator mainly used to replace the Baseband and modulator sections of analog radio links. Using robust QPSK modulation, this device has a high degree of tolerance to RF units' non-linearity and low quality specifications while keeping a high data throughput. Different coding rated along with good channel equalization and signal recovery algorithms make the demodulator the best choice to upgrade analog radio links to digital. This unit is best matched with Pardis DRS-1012 or any professional DVB-S transmitter.
