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.
Features
Two independent phasemeter channels with output options
Track and record the phase, frequency and amplitude of two 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
Flexible signal tracking options
Phase-locked loop tracking bandwidths from 10 Hz (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

Simultaneously measure
phase, frequency and
amplitude
Based on a phase-locked loop architecture, Moku:Lab’s Phasemeter measures the phase, frequency and amplitude of an input signal at the same time.

Auto-acquisition mode
In auto-acquisition mode, Moku:Lab’s Phasemeter will automatically detect and lock to the tone with the greatest magnitude with better than 100 mHz accuracy.

Phase-locked outputs
Generate up to two DC to 200 MHz sinewaves with the option to phase-lock them to their corresponding input signal.

Realtime spectral analysis
Analyze measurements in the time and frequency domains, including Allan deviation, power and amplitude spectral densities.
