Phasemeter overview

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.

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)

Simultaneously measure phase,
frequency and amplitude

Based on a phase-locked loop architecture, Moku:Lab’s Phasemeter measures the phase, frequency and amplitude of an input signal at the same time.

Auto-acquisition mode

In auto-acquisition mode, Moku:Lab’s Phasemeter will automatically detect and lock to the tone with the greatest magnitude with better than 100 mHz accuracy.

Phase-locked outputs

Generate up to two DC to 200 MHz sinewaves with the option to phase-lock them to their corresponding input signal.

Realtime spectral analysis

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