International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the development of a PC based IRIG tone generator and flight termination transmitter. The tone generator and flight termination transmitter card are part of a flight line test set. The test set has several PC based cards which include an S-Band telemetry receiver, a bit synchronizer, a decommutator, an encryption support card and the flight termination transmitter card. The test set can perform a complete end to end test of a weapon’s flight termination system prior to loading on an aircraft.
