Dear all,
I would like to measure the rise and fall time of a short pulse over a
non-grounded capacitor. The pulse is 1kV amplitude and typical rise
and fall time are some ns. Pulse width is about 100ns.
I have in mind to use 2 Tektro P5100 probes connected on each side of
the capacitor and use A-B maths function of TDS5052B oscilloscope to
evaluate the signal performance. According to datasheet, P5100 is a
x100 probe with 250MHz BW (rise time 1.75ns) with loading of 10Meg and
2.75pF.
I was told that it would be better to use a differential probe P5205.
But this probe has 100MHz BW and loading of 4Meg / 7pF each side. I
have not such a probe today.
I would like to have a measurement error less than about 5ns.
I would appreciate your comment which method has the best accuracy or
any other proposal.
Best regards,
Francis
