The Model 226 Telemetry Synchronizer System (TSS) provides PCM bit synchronization, telemetry frame synchronization and decommutation, telemetry data quality monitoring, NASA 36 time code appending, and interfacing to a Westinghouse TACTS/ TELEM telemetry card, or a DEC DRV11-WA parallel interface adapter. It has multiple program selectable inputs to accept serial PCM data streams to an internal bit synchronizer or the frame synchronizer from an external source. NASA 36 time code is decoded internally and appended to the telemetry data and status output. Statistical data quality monitoring is provided and reported in four display words. Up to four data words may be captured from the telemetry stream and displayed on the front panel.

All functional operations of the TSS are controlled from a front panel display and keyboard or by way of the remote control interface. All front panel functions, including data displays, are also accessable in the remote control interface. Non-volatile ram on the internal system controller records the last setup for restoration upon power-up.

The TSS is suitable for use in telemetry data quick look as well as data acquisition and processing systems. This unit has been used to support the GOES weather satellite data format and contains all of the features needed to support general purpose telemetry data acquisition. The decommutation function allows presentation of true measurements from the synchronized data stream in the exact form required for processing. Its configurable computer data transfer interface is designed to permit it to be adapted to almost any computer. The remote control interface provides all of the functionality to permit the unit to be operated completely unattended.
