Lockin Amplifiers

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 range of lock-in amplifiers to meet different requirements. We also offer a DSP based lock-in amplifier manufactured by Zolix Instruments.
