Phasemeter

For more information on the Moku Go, Pro and Lab series specifications and applications visit the blog “Are you looking to combine your laboratory into one portable Moku Lab?” or download the datasheets from the download tab.

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.

Moku:Pro’s Phasemeter measures phase (relative to a reference clock) of up to four input signals with better than 6 µradian precision from 1 kHz up to 300 MHz. Based on a digitally implemented phase-locked loop architecture, Moku:Pro’s Phasemeter provides exceptional dynamic range, zero deadtime, and measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.
