Bandwidth (up to)
1 kHz to 200 MHz
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.
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
Measuring Allan Deviation
Input frequency range
1 kHz – 200 MHz (auto-acquire or manually specify)
Frequency set-point precision

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