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.

Allan deviation on 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.

mokupro-phm

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.

Phasemeter real time data analysis

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.
