Moku:Lab’s Phasemeter measures phase of up to two input signals with better than [nb-hyphen]6 µradian[/nb-hyphen] precision from [nb-hyphen]1 kHz[/nb-hyphen] up to [nb-hyphen]200 MHz.[/nb-hyphen] 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_specs_wrapper title=”Features”][features_specs_column]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[/features_specs_column][features_specs_column]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
