Description


Pair of Apollo Command Module signal conditioners manufactured for NASA by Autonetics, each measuring 2.25″x 3.25″ x .75″, one labeled on the side as "Attenuator-Isolation, ME 901-0546-0003, Ser. No. 06359-4437 EWA, Contr. No. NAS9-150," and the other labeled, "Converter-Variable, Resistance to DC, ME 901-0256-0001, Ser. No. 06359-3192 EWA, Contr. No. NAS9-150." Both bears Autonetics inspection seals, one dated January 28, 1968, and the other marked June 22, 1966. In overall fine condition.

Signal Conditioners were utilized on the Command Module as a type of converter to transform signals from sensors and transducers to basic 0 to 5 volt DC instrumentation analog (coded measurements) voltage level. The sensors and transducers measured all sorts of things from temperature, pressure, vibration, propellant consumption rates, and so on. Output of the Signal Conditioners provided a signal compatible with data collection and display equipment on the spacecraft.
