Moku:Pro Phasemeter
Compare all phasemeters
Overview
The Moku:Pro 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, the Moku:Pro 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
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, or drive measured phase to output with V/cycle setting and phase wrap options
Drive measured amplitude, phase, or frequency offset for closed-loop control systems
Real-time data analysis support
Real-time spectral analysis to display and save Power Spectral Densities, Amplitude Spectral Densities, Allan Deviation, and more
Output frequency multiplier
0.125x to 250x (phase-locked to input)
Flexible signal tracking options
Phase-locked loop tracking bandwidths from 1 Hz (great for tracking low SNR signals) up to 1 MHz (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
