Moku:Lab’s Phasemeter measures phase of up to two input signals with better than 6 µradian precision from 1 kHz up to 200 MHz. Based on a digitally implemented phase-locked loop architecture, Moku:Lab’s phasemeter provides exceptional dynamic range, zero dead-time and measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.

  • Two independent phasemeter channels with output options : Track and record the phase, frequency and amplitude of two independent signals
  • Phase-locked output option enables you to generate sine waves that are phase-locked to the inputs.
  • Real-time data analysis support : Real-time spectral analysis to display and save Power Spectral Densities, Amplitude Spectral Densities, Allan Deviation and more.
  • Flexible signal tracking options : Phase-locked loop tracking bandwidths from 10 Hz (great for tracking low SNR signals) up to 10 kHz (ideal for signals with large dynamics). Free-wheeling mode intelligently holds the loop state when the signal fades unexpectedly and automatically re-engages when it returns.
  • 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.
  • Sine wave generators : Dual channel 250 MHz (manual or input-locked).
