Accurate measurement of pulse fall time with low side MOSFET?

<< < (2/2)

Vasik041:
With such high voltage you can try using 1 : 100 probe
Probe has known (quite small) capacitance, you can take it into account in you measurements if it has significant influence.

I should mention that this MOSFET is going to operate from with a Vs of 50v to 4kv, DC.

The problem is no longer the same if the voltage must exceed the KV. There I have no real solution. To measure the voltage accurately, a very expensive high voltage probe is needed..
