Frequency Response Measurement with Chirps and Leakage-Free FFT

on 28.10.2016 at 16:08 by brunok
Introduction This post explains how to measure the frequency response of a component or system with high spectral resolution in a minimum amount of time. Rather than sweeping the frequency and recording each spectral point individually, the approach presented here is […]

Better Amplitude Accuracy with MFLI Analog Adder

on 07.03.2016 at 17:47 by brunok
Many lock-in applications use a drive signal consisting of a small AC excitation voltage and larger DC offset voltage, for example differential conductance (dI/dV) measurements. Users of the MFLI Lock-in amplifier have the choice between two methods to generate such a signal: […]
