Phasemeter

The Moku Phasemeter measures the phase, relative to a reference clock, of up to four input signals with better than 6 μradian precision from 1 kHz to 300 MHz. Built on a digitally implemented, phase-locked loop architecture, the Moku Phasemeter provides exceptional dynamic range, zero dead time, and measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.

The Moku Phasemeter is easy to use and offers a range of advanced capabilities to optimize your experiment — at the most cost-effective price in the industry.

Moku:Pro Phasemeter

Leverage multi-channel phase, frequency, and amplitude measurements to unlock greater insights

Utilize up to four independent channels for maximum performance. It’s easy to generate sine waves that are phase-locked to the inputs, divided down up to 0.125x or multiplied up to 250x. You can also seamlessly drive measured phase to output with V/cycle settings and phase wrap options. With a phase-locked loop architecture, the Moku Phasemeter continuously tracks the phase, frequency, and amplitude of an input signal at the same time.

mokupro-phm

Work smarter with flexible signal tracking options

Measure signals with phase-locked loop tracking bandwidths from 1 Hz (great for tracking low signal-to-noise ratio signals) to 1 MHz (ideal for signals with large dynamics).

Phasemeter real time data analysis

Real-time data analysis for better signal visualization

Analyze measurements in the time and frequency domains, including Allan deviation, power spectral densities, power, and amplitude spectral densities.

Moku:Lab Phasemeter

Freedom in the lab when you need it

Simultaneously measure phase, frequency, and amplitude without being tethered to your lab bench. Conduct real-time spectral analysis from the intuitive iPad app while moving freely throughout the lab.

Moku:Go Liquid Instruments
