ABSTRACT:
A programmable telemetry word selector includes a scanning memory storing, or each of a number of analog outputs of the selector, a variable identifying tag and a data conversion code for the variable. The selector is constructed to compare the stored tags with successive tag words provided by a telemetry data compressor and, when a match is found, perform on a corresponding data word from the compressor digital data conversions specified by the code and direct the result to the corresponding analog output. The word selector is constructed to perform the scanning, digital conversion steps, and analog conversion concurrently so as to handle tags and data provided relatively rapidly by the compressor. The selector includes a storage memory for a plurality of sets of the scanning memory contents and has a microcomputer for generating and modifying the sets to reconfigure the selector for different tests providing telemetered data.
