Moku:Go Phasemeter
Compare all phasemeters
Overview
The Moku:Go Phasemeter measures phase (relative to a reference clock) of up to two input signals with better than 1 nanoradian precision from 1 kHz to 30 MHz. Based on a digitally implemented, phase-locked loop architecture, the Moku:Go Phasemeter provides exceptional dynamic range, zero dead time, and measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.

Key features
Two independent phasemeter channels with output options
Track and record the phase, frequency, and amplitude of two independent signals.
The phase-locked output option enables users to generate sine waves that are phase-locked to the instrument’s inputs with configurable frequency scaling from 0.125x to 250x.
Flexible signal tracking options
Phase-locked loop tracking bandwidths from 1 Hz (great for tracking low SNR signals) up to 100 kHz (ideal for signals with large dynamics).
Real-time data analysis support
Real-time spectral analysis to display and save power spectral densities, amplitude spectral densities, Allan deviation, and more.
Applications
Oscillator analysis
Optical/ultrasound ranging
Gravitational wave detection
Interferometry
Phase-locked loop

Simultaneously measure phase, frequency, and amplitude
With a phase-locked loop architecture, the Moku:Go Phasemeter continuously tracks the phase, frequency, and amplitude of an input signal at the same time.

Phase-locked output capabilities
Generate sine waves that are phase-locked to the inputs at the fundamental frequency or harmonics with configurable frequency scaling from 0.125x to 250x.
