Phasemeter

Digital phase-locked loop architecture
The Phasemeter is a unique instrument that provides exceptional dynamic range, zero dead-time, and measurement precision that exceeds the performance of conventional lock-in amplifiers and frequency counters.

Real-time data analysis support
Display and save Power Spectral Densities, Amplitude Spectral Densities, Allan Deviation, and more with integrated real-time spectral analysis tools.

Output configuration options
The phase-locked output option enables users to generate sine waves that are phase-locked to the instrument’s inputs with configurable frequency scaling from 0.125x to 250x.

Flexible signal tracking
Phase-locked loop tracking bandwidths from 1 Hz (great for tracking low SNR signals) to 1 MHz (ideal for signals with large dynamics).

Applications
• Oscillator analysis
• Optical / ultrasound ranging
• Gravitational wave detection
• Interferometry
• Phase-locked loop
