Hello expert,

Let me confirm a test point of phase margin.

Is it OK to measure the phase margin at red point?

Best regards,

Hi Katsu-san,

Yes, you could inject the test signal there. Here in the lab, we are using bode100 for loop response, here is an app note from them that gives an example on how the loop phase measurement is done with a Bode100.
