A Precision Voltage Reference Unit for Calibrating Airborne Data Acquisition Systems.

Abstract

A precision voltage reference unit is described which enables the accuracy and precision of flight data acquisition systems to be measured under operational conditions. Two versions have been designed having outputs of 8mV and 4V which simulate 80% of the full scale output respectively, of low level (10mV) and high level (5V) transducer outputs, and a range of source impedances is also simulated. The voltage stability of the units is better than 0.01% for the high level version and 0.1% for the low level version, over the temperature range -40 to +80 C. The design is such that the magnitude of a number of error sources (e.g. common mode voltages, system input impedances, and offset voltages and currents) can be determined. (Author)
