Current Probe Bandpass
« on: 05-19-2017 -- 16:36:20 »
I am verifying bandpass of high frequency current probes by discharging a large stored voltage through an air gap and measuring the risetime of the current probe on an oscilloscope.

I'm using the diagram from MIL-STD-461G (2 MAR 2015) on page 98 to construct the RC network
http://www.interferencetechnology.com/wp-content/uploads/2015/04/461G.pdf

I'm using the observed risetime (limited by my oscilloscope's capability) to determine the actual bandpass of the current probe using BP = 0.35/RT

I believe the RC network is the MIL standard is intended to simulate a human body and is not relevant to the observed risetime.

Any observations?
