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.

Specifications |
- Track and record the phase, frequency and amplitude of two independent signals
- Phase-locked loop tracking bandwidths from 10 Hz (great for tracking low SNR signals) up to 10 kHz (ideal for signals with large dynamics)
- Real-time spectral analysis to display and save Power Spectral Densities, Amplitude Spectral Densities, Allan Deviation and more
- Free-wheeling mode intelligently holds the loop state when the signal fades unexpectedly and automatically re-engages when it returns
- Phase-locked output option enables you to generate sine waves that are phase-locked to the inputs

Available on
Track your signal’s phase, frequency, and amplitude, all from an intuitive iPad interface, or with Python, MATLAB, and LabVIEW.
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.
F.A.Q
Can I measure the phase or frequency difference between the two input channels?
Yes! When both input channels are enabled, a Delta channel with the difference between Channel 1 and Channel 2 automatically appears. You can also plot the Delta channel alongside Channel 1 and 2 in the Timeseries and Spectral Analysis plots by selecting the Δ icon (color-coded orange).
