Phasemeter

Phase precision

6 µradians/√Hz


Bandwidth (up to)

10 kHz


Frequency range

1 kHz to 200 MHz


Data Logger

Integrated

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

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

Specification

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)
