description abstract	Abstract: While radio frequency (RF) Shuttle Main Engine telemetry data was being recorded during the vehicle ascent phase of STS-123, off-nominal noise in the data stream, combined with the use of a predefined and preset pulse code modulation (PCM) bit synchronizer, invalidated some of the Shuttle Main Engine data. Investigations revealed a deficiency in the telemetry station recording process, which was subsequently resolved by changing the RF data recording format from digital to analog.
