Automated instrumentation system verification
Abstract
This report describes the efforts and results of automating systems verification for the instrumentation equipment used in high explosives testing. A complete checkout of instrumentation channels from sensor connection to, and including, data reduction is achieved by measuring linearity, frequency response, and dynamic range simultaneously of as large a group of channels as is practical at one time. Inputs are a triangular wave signal and a noise signal. The checkout data are recorded in the same way as test data. A table that is ordered by recorder track and voltage controlled oscillator center frequencies is produced in the course of the computer program to contain percent linearity, 3 dB bandwidth, percent deviation from standard bandwidth, dynamic range in decibels, and noise floor in millivolts for every channel measured. Hardcopy plots of the nonlinearity deviations, the frequency response, and the noise floor spectrum can be produced during processing when requested. The computer program is friendly, the order of channel measurements can be completely arbitrary, repeated measurements replace the respective previous entries.
