Lock-in amplifiers use phase-sensitive detection to measure the presence of small signals buried in large amounts of noise. By measuring the coherent system response from an incoming AC signal, the ...

New technologies often require precise measurements of tiny signals buried in noise. This webinar will teach you how to use lock-in amplifiers and optimize the measurement parameters. We discuss three ...

The dual approach of digital and analog lock-in amplifier technologies has continued to advance the precise extraction of weak signals from noise-laden environments. These devices are indispensable in ...
