  MODEL 8500D/8501D DIGITAL SUBCARRIER GENERATOR AND DEMODULATOR
This composite subcarrier system transmits the entire BTSC composite baseband– Stereo, SAP, and Pro Channel– from the studio to the transmitter site utilizing only one microwave subcarrier frequency. The wideband signal “fits” into the 700 kHz subcarrier space normally occupied by ordinary monaural subcarrier systems without interference or sacrifice in performance. Can be used to feed 4.5 MHz to a cable system.
