Title: Differential probe testing setup
Post by: TMaxElectronics on July 02, 2020, 12:20:18 PM

I have just bought a Micsig DP10013 differential probe and would like to test its step response, and am looking for a test setup...

My signal generator only goes to 15Vpp. Not sure if that is comparable to a 300v swing.
I did think about using my tesla coil primary bridge with a load resistor, but I'd expect that to have some ringing just by itself... I could of course try to eliminate that (verifying it with my normal probe) and the switching to the differential one, but somehow that feels inaccurate and i'm not sure if I could even remove all ringing.

Do you have any better suggestions?

Thats a well controlled way to produce a pulse with a very fast rising edge, probably way faster than your diff probe.  Ideal for checking a step response.

I remember seeing that somewhere, but didn't remember.
Thanks alot :D

I'll publish what I measured once I did ;)
