Abstract

A digital phase sensitive detector (PSD) has been designed and built which may be used in conjunction with a SQUID-based AC susceptibility measurement system. The system operates in a useful frequency range from 2 mHz-2 kHz and measures both in-phase and the quadrature component. The digital PSD, which is based on a small minicomputer, corrects for DC drift and flux quantum jumps of the SQUID and operates in 'real time'. An analysis of its design and several properties and measuring results are presented
