CF-5200 Frequently Asked Questions

SIN sweep outputs signals that match the analysis frequency (frequency resolution), so there is no need to convert to spectral density.
In the new version, when measuring the frequency response function with a sine sweep, it automatically applies a rectangular window.

In the case of random signals, the spectral density is used with a Hanning window.
