How to get the frequency response between two measurement points in simulink?

Hello all,

In my simulink model, I have specified one "input perturbation" signal and two "output measurement points" for frequency response estimation. By default, the frequency response estimator gives me the frequency response data between the input purturbation point and each of the two output measurement points (two frd objects). However, I wanted to know how to obtain the frequency response data between the "output measurement point 1" and "output measurement point 2"?

Hi, when you do frequency response estimation, the tool injects a sinestream signal into the model at the input and collects the response at the output. It then computes the frequency response. So if you need to compute frequency response between two points, specify the one where you want sinestream signal injected as the input and the other one as output.

Hope this helps.
