A phase-locked amplifier is an amplifier that performs phase-sensitive detection on alternating signals. It utilizes a reference signal with the same frequency and phase relationship as the measured signal as a comparison benchmark.
The phase-locked amplifier responds only to the signal being measured itself and to noise components that are at the same frequency (or harmonics thereof) as the reference signal and are in phase. Therefore, it can significantly suppress unwanted noise and improve detection
Measure signal-to-noise ratio. Additionally, the phase-locked amplifier offers high detection sensitivity, with relatively simple signal processing, making it an effective method for detecting weak light signals.

The SR830 utilizes Digital Signal Processing (DSP) technology, offering phase stability about a hundred times higher than analog products, featuring high stability and two major phase noise suppression characteristics.
