Liquid Instruments SW-Lab-PHS Phasemeter Upgrade

Overview

The Liquid Instruments SW-Lab-PHS is a high-precision phasemeter module for the Moku:Lab platform that measures phase of up to two input signals with exceptional precision from 1 kHz to 200 MHz. The module features a digital phase-locked loop architecture that provides superior dynamic range, zero dead-time measurement, and precision exceeding conventional lock-in amplifiers and frequency counters.
