Has anyone ever used an Analog Discovery 2 and an injection transformer for power supply loop stability measurements?
I am using the TEKBOX TBJT02, 1Hz - 5MHz, 5Ω terminated, 1:1 injection transformer.
I'm using this setup to measure the frequency response of a LM5157EVM-BST Evaluation Module and comparing it to TI's posted Bode plots in the datasheet for the EVM.
I'm am able to come up with something somewhat close, so I think it is working, but I had to turn up the waveform gen on the Disco to 1V. My colleague has concerns that injection voltage would end up changing the operating point of some supplies.
Has anyone else run into the Analog Disco 2 not outputting the correct voltage or maybe the injection transformer is attenuating the signal?

Any insight would be very much appreciated.
