Lockin Amplifiers

August 9, 2018

Lockin amplifiers are instruments designed to recover signals that are buried in noise. They require a reference signal at the same frequency as the signal that is being measured and then use this to demodulate the input signal before filtering.

Scitec produces a wide range of lock-in amplifiers to meet different requirements. If you can’t find what you want then please contact us and we will try and help.
