Lock-in Amplifiers

Lock-in amplifiers measure the amplitude and phase of signals obscured by noise. Common uses include recovering signals lost in noise and capturing high-resolution measurements of clean signals. They are also ideal test systems for a variety of other applications—measuring noise itself, determining a signal’s phase shift, or even taking the place of a range of measurement devices.

Lock-in amplifiers can be divided into analog and digital systems.
  • Analog variants demodulate a signal by means of analog frequency mixers and RC filters, allowing users to single out the component of the signal at a specific frequency and phase.
  • Digital variants utilize digital signal processing (DSP) to demodulate signals, increasing the speed and efficiency of the measurement.
