The Factum Radioscape NC200A/IC is an Encoder/QPSK Modulator for NICAM 728 System B/G, D/K and I. The Encoder is mainly used in broadcasting networks, but also used for CATV and in laboratories. The output is a QPSK modulated carrier at intercarrier frequency, locked to the bit-rate. The NC200A/IC converts analogue stereo sound via A/D conversion of two sound (stereo) channels, Transcoding of digital sound signals to NICAM format and QPSK modulation. Options include a 2-channel version and an Encoder-only version with Data + Clock output.
