Overview

This is not your ordinary frequency counter. Moku:Phasemeter is based on a digital phase-locked loop architecture and can track two independent signals from 1 kHz to 200 MHz. Measure phase changes of less than a millidegree with a sensitivity of better than 100 nanocycles/√Hz. Record frequency fluctuations with zero dead time.

Features


  • Track and record the phase, frequency and amplitude of two independent signals
  • Phase-locked loop tracking bandwidths from 10 Hz (great for tracking low SNR signals) up to 10 kHz (ideal for signals with large dynamics)
  • Real-time spectral analysis to display and save Power Spectral Densities, Amplitude Spectral Densities, Allan Deviation and more
  • Free-wheeling mode intelligently holds the loop state when the signal fades unexpectedly and automatically re-engages when it returns
  • Phase-locked output option enables you to generate sine waves that are phase-locked to the inputs

Specifications


  • Input frequency range: 1 kHz – 200 MHz (auto-acquire or manually specify)
  • Frequency set-point precision: 3.55 µHz
  • Tracking bandwidth: 10 Hz, 40 Hz, 150 Hz, 600 Hz, 2.5 kHz, 10 kHz
  • Frequency precision up to 10 µHz/√Hz
  • Phase precision up to 100 nanocycles /√Hz
  • Data logging rates: 30.5 Hz, 122 Hz, 488 Hz, 1.95 kHz, 15.6 kHz, 125 kHz
  • Dual channel 250 MHz sine wave generators (manual or input-locked)

F.A.Q.


  • Can I measure the phase or frequency difference between the two input channels?

    Yes! When both input channels are enabled, a Delta channel with the difference between Channel 1 and Channel 2 automatically appears. You can also plot the Delta channel alongside Channel 1 and 2 in the Timeseries and Spectral Analysis plots by selecting the Δ icon (color-coded orange).
