Lock in amplifier
Model：SR830
Overview
Digital lock-in amplifier is an instrument used to detect the strength (amplitude) and phase of weak AC signal in strong noise environment. They are widely used to extract weak optical signals. The digital signal processing DSP lock-in amplifier SR830 produced by SRS company provides you with higher performance at a reasonable price. SR830 has the function of displaying the size and phase of the signal at the same time. They replace the demodulator, output filter and amplifier in the traditional lock-in amplification with digital signal processing technology, and have an operating frequency range from 1MHz to 102khz and drift free dynamic storage of 100dB.Description
