Moku:Lab’s Phasemeter measures phase of up to two input signals with better than 6 μradian precision from 1 kHz up to 200 MHz. Based on
a digitally implemented phase-locked loop architecture, Moku:Lab’s Phasemeter provides exceptional dynamic range, zero dead-time and
measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.

Points Clés
