Paper Abstract

The cold focal plane for the Enhanced Thematic Mapper (ETM) contains three spectral bands: two 16-element PV InSb bands and one 4-element PC HgCdTe band. The paper discusses the design of the entire analog video chain which includes detectors, preamplifiers, and the postamplifiers. The PV bands have a 52-kHz signal bandwidth and the PC band has a 13-kHz bandwidth. A semiautomated test set with a modulated GaAs LED for transient optical inputs, was designed to measure the stringent performance requirements in both the frequency response and transient response. The paper shows some of the test results.
