Requirements document for mini system test unit

Abstract

The mini system test unit (STU) for the Trace Gas Analyzer (TGA) is defined. The interface signals of the components used to implement the STU are also defined. The mini STU is used to support pre-flight ground test operations. The STU indications of TGA operation (organic and carbon monoxide analyses) and its ability to monitor gas chromatograph and mass spectrometer test signals are included.
