Paper Abstract

The design and construction of a system to test common module detector dewar assemblies with a simulated cooler vibration is described. Pseudo-random vibration levels up to 10 g RMS at frequencies up to 20 kHz can be applied to the unit under test, with control accuracy better than 1 dB. A test time of about 3 seconds per element is routinely obtained for arrays up to 180 elements. The system is software configurable to address a variety of testing requirements; vibration levels and frequencies and noise analysis frequencies and bandwidths are variable. Unique features of this system include a true three axis vibration control system which is integrated into the main system controller, and a custom built 180 channel preamplifier/multiplexer array, and a small size and quiet operation for production area compatibility. The system is compatible with a family of plug in preamplifier cards, further enhancing its adaptability. The system has been in continual use for several years and has proven to be versatile, adaptable, and reliable.
