Computer controlled testing of telemetry ground stations

SCATS (Self-Check Automated Telemetry System) is a minicomputer-controlled system for testing telemetry ground stations. The tests implemented are antenna figure of merit, intermediate frequency SNR, bit error probability, noise power ratio, and tape recorder frequency response. SCATS can test a telemetry system in about one-fifth the time it takes to manually test the system. The test results are printed out and can be stored on the computer for trend analysis and other statistical analyses; the system accuracy is + or - 1.0 dB.
