Digital Transmission Evaluation Project RDS-80G Test.

Abstract

The Raytheon RDS-80G digital multiplex/radio system was tested in back-to-back and actual link configuration for determination of transfer parameters and to develop standard test techniques. The system has a maximum propagation rate of 20.85 Mb/s (312 voice channels) in a 14 MHz bandwidth in the 8 GHz band. BER vs RSL characteristics are displayed and analyzed as the primary mode of equipment evaluation. Actual link data is presented for analysis of cross-polarization characteristics and fading at two microwave frequencies. Carrier to interference data, T1 line tests and theoretical predictions are compared. Frequency stability, data rate variations, pulse jitter, switching errors, and frame time were measured and discussed. Power spectral density characteristics are compared to FCC spectrum requirements. (Author)
