I want to use the Bode 100 Vector Network Analyzer to measure the frequency response of my circuit. I understand that with voltage feedback, a typical injection transformer can be used at the feedback loop.
I'm working with a circuit that uses current feedback rather than voltage feedback. The current is sensed through a current transformer, and the feedback is processed by a microcontroller.
However, I'm unsure how to properly inject a signal and measure the response for a current feedback system.
Specific questions:
1.Where should the injection signal be applied in a current feedback loop?
2.How should the Bode 100's channels be configured to measure the loop gain?
