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.
Key benefits
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.
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.
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).
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.
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.
Engineered to work seamlessly with your favorite APIs
API integration with MATLAB, LabVIEW, and more allows straightforward automation of your Moku device in complex setups or for repetitive tasks. Save your measurements, screenshots, traces, and other settings locally or to your preferred cloud app. You can also send work to yourself or colleagues within the Moku app.
