- For the drain-to-source voltage waveforms connect the high voltage probe tip to TP2 and the
probe ground to test point TP1.
- For switching current waveforms replace jumper TP2 with a wire loop and use a Tektronix
A6302 current probe and AM503 current probe amplifier (with TM501 power module) or
equivalent.
