Moku:Pro’s Phasemeter

Compare all phasemeters

Overview

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.

Key features

Four independent phasemeter channels with output options
Track and record the phase, frequency, and amplitude of four independent signals.

Phase-locked output option enables you to generate sine waves that are phase-locked to the inputs.

Real-time data analysis support
Real-time spectral analysis to display and save Power Spectral Densities, Amplitude Spectral Densities, Allan Deviation and more.

Built-in analysis
Allan Deviation

Flexible signal tracking options
Phase-locked loop tracking bandwidths from 10 mHz (great for tracking low SNR signals) up to 10 kHz (ideal for signals with large dynamics).

Free-wheeling mode intelligently holds the loop state when the signal fades unexpectedly and automatically re-engages when it returns.

Applications

Oscillator analysis

Optical/ultrasound ranging

Gravitational wave detection

Interferometry
