Abstract
A phase-sensitive detector is described which features programmable gain, digital output, and a resolution of 0.02 ¿V. The instrument suppresses harmonic sensitivity through the use of analog circuitry which multiplies the signal by constant amplitude sine and cosine waves derived from an external reference of arbitrary voltage and frequency.
