Overlap the DUT Frequency Response at different generator levels

Overlap the DUT Frequency Response at different generator levels

In this article we will explain how to simultaneously measure and visualize the frequency response of a DUT (Device Under Test) for different generator output levels of our Audio Precision analyzer.

1) After programming the Signal Path Setup within the relevant Sequence Mode sequence, we added the Frequency Response measurement:

2) Within the Frequency Response measurement, within the Nesting section, we select as Secondary Source "Gen Level" and press Edit to manually indicate the different levels of the generator to which we want the measurements to be carried out:

3) We press Start and the different measurements will be executed, showing all the results simultaneously in the same chart.
