Phase Detection with Lock-in Amplifier and Phasemeter

Thursday, September 14, 2023
Liquid Instruments

Precise and sensitive phase detections are often required for impedance and optics-based measurements. For example, measuring the phase shift between current and voltage reveals the complex impedance of a device or component. Very small displacements can be measured by the phase shift between control and measurement arms from an optical interferometer. The Lock-in Amplifier and the Phasemeter are well suited to detect the phase of a radio frequency signal. In this application note, we will introduce the working principles of these instruments and provide an instrument selection guide for different measurement scenarios.
