Phasemeter
Designed by researchers for demanding measurement applications, the Moku Phasemeter is optimized to provide precise phase measurements. Measure phase, frequency, and amplitude with better than 1 nanoradian precision using a digital phase-locked loop architecture with exceptional dynamic range, zero dead time, and measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.

The Moku Phasemeter exceeds the performance of conventional oscilloscopes, lock-in amplifiers, and frequency counters in terms of precision and accuracy. Watch the video to learn more.
Key benefits of the Moku Phasemeter
With real-time graphs, the ability to generate outputs phase-locked to the inputs, and an integrated Data Logger, you can expect more from the Moku Phasemeter.
Track measurement results in real time with built-in graphs
With real-time graphs, you can focus on making measurements, not manipulating data. Analyze measurements in the time and frequency domains with plots of overlapping Allan deviation, time series data, power spectral density, amplitude spectral density, Rayleigh spectrum, and coherence with no additional programming or post-processing required.
Leverage multi-channel phase, frequency, and amplitude measurements
Utilize up to four independent channels for maximum performance. Generate sine waves that are phase-locked to the inputs, divided down up to 0.125x or multiplied up to 250x. With a digital phase-locked loop architecture, the Moku Phasemeter continuously tracks the phase, frequency, and amplitude of an input signal with high precision.
Track signal phase over a wide range of frequencies
Measure signals with phase-locked loop tracking bandwidths from 1 Hz to 1 MHz. Ensure accurate signal measurements even in noisy environments with phase sensitivity in the µcycle level, corresponding to optical metrology sensitivities at the picometer level.
Engineered to help you focus on the work that matters
With an intuitive GUI, built-in data visualization, and fully embedded data logging, the Moku Phasemeter can help you save countless hours of development time to build solutions, capture meaningful data, and analyze results in post-processing.
