Anybody know if it is possible to read 5000v pulses on a digital
scope, the TDS 1002 from Tektronic.
I have this unit, taking the voltage from a 12v car battery and
supposedly giving off pulses of 5000v to 6000v. I want to see what
kind of pulses.
If it is possible , how do I go about it.??
** Buy 10 x 2kV ceramic caps of 100pF each - wire them all in a
series string and put that inside a plastic tube.
Connect a 10 nF cap ( say 500 V) across the tip and ground of your scope
probe.
Connect the string of caps between the source of pulses and the probe tip.
Ground the scope to the common of the pulse source.
You have just made a 1000:1 capacitive divider probe.
The input load is only 10pF.
6 kV pulses will show as 6 volts ones on the scope.
