A Pulse-Height Analyzer for Space Application

A number of investigations, suitable to be performed from space vehicles, make use of nuclear pulse spectrometry as an instrumentation method. The Jet Propulsion Laboratory program described here was designed to provide a pulse-height analyzer of sufficient precision and versatility as to be suitable for any of a number of such spaceborne investigations. The analyzer may be commanded inflight to perform pulse-height analysis, time analysis, or multiparameter analysis. Instruction storage, data storage, and data readout, including a data compression option, are provided internally.
