Multi-Channel Spectrum Analyzer (MCSA)

The Multi-Channel Spectrum Analyzer (MCSA) was the detector, together with its software algorithms, which was at the heart of the instrumentation used in the targeted portion of NASA's High Resolution Microwave Survey. Developed at NASA Ames Research Center and built under contract to Ames by the Silicon Engines Company, the first operational version, known as MCSA 2.0, was capable of simultaneously analyzing 14 million 1-hertz channels. This represented a 10 millionfold increase in capability over the total of all previous searches.
