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.

Below is the Phasemeter’s user interface showcasing some of the key features explained below:

Key Features of the Phasemeter:

Leverage multi-channel phase, frequency, and amplitude measurements to unlock greater insights with the Moku Phasemeter

Utilise 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 visualisation in the Phasemeter

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

 

Mobility in the lab when you need it

Adjust your experiment setup and simultaneously make measurements from the intuitive iPad app while moving freely throughout the lab. Or fully untether from the bench with the Apple Vision Pro for the ultimate optics lab experience.

 

Engineered to work seamlessly with your preferred APIs

API integration with Python, MATLAB, and LabVIEW 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.

Applications:

  • Oscillator analysis
  • Optical/ultrasound ranging
  • Interferometry
  • Directed energy
  • Gravitational wave detection
