Sideband Analysis with Lock-in Amplifiers

on 27.02.2014 at 20:10 by Sadik on Blog of Sadik Hafizovic
When a sinusoidal waveform is periodically modulated in either amplitude or frequency sidebands are generated as a result of this carrier modulation. These sidebands can be measured using a lock-in amplifier. Zurich Instruments lock-in amplifiers (HF2LI and UHFLI) can measure […]
