Hello, i am newbie to oscilloscope and i would like to measure with oscilloscope the gate of IGBT module. The manufacturer give the rights waveform as in the attached file.
I have set the oscilloscope in MATH functions (-) and i put the probes on GATE and EMMITER of IGBT, in order to see the waveform, but this is strong affected by the EMMITER - GROUND voltage.
How i can measure the GATE - EMMITER voltage right?
