The Raytheon RDS-80 digital microwave radio system was tested in back-to-back configuration for determination of transfer parameters to isolate propagation effects in link testing and the development of standard test techniques. The system includes duplex radio and multiplexers and propagates 40.15 Mbs 600 voice channels at 11 GHz in each of two orthogonal planes, for a 1200 voice channel total capacity. BER vs RSL characteristics are displayed and analyzed as the primary mode of equipment evaluation. Carrier-to-interference data, multiple hop performance, T-1 line tests, and theoretical predictions are compared and studied. Power spectra is displayed and conclusions are drawn with respect to proposed acceptance criteria for Four Phase Shift Keying equipment.
