Hi All, Jim has a good idea here. I have an experiment I use in presentations that shows the amount of an ESD current that couples onto a probe body (Fischer F-33-1) varies by about a factor of two depending how the lead is dressed as it passes through the probe, perpendicular through the center

Brent, Good idea. I have used making tape to form a thick collar around the cable insulation. This takes time, but provides very repeatable measurements (positioning). I did this with a Fischer F-2000 probe, which has a small diameter hole. Jim

Jim, I too have played with a sliding probe to find peaks and nulls on cables. Typically this is for diagnostics purposes only. In order to minimize some of the uncertainty I will typically place one or two ferrite toroidal cores on the coaxial cable leaving the current probe as a common mode

Wrapping a strip of bubble pack around the cable a few time is also an easy way to keep it centered in the clamp. Brent -Original Message- From: owner-emc-p...@majordomo.ieee.org [mailto:owner-emc-p...@majordomo.ieee.org]On Behalf Of Lacey,Scott Sent: Monday, June 21, 1999 11:47 AM

Jim, I have experience using current probes on cables carrying differential digital signals at 500 MHz and above. I find that standing waves are ALWAYS present on the shield of the cable, even when the signal circuits are matched (at least as well as practical). Most of the following experience

In my opinion, letting the cable insulation touch the probe body is never a good idea. I always try to shim the cable and probe in order to center the cable within the probe opening. The trick is to keep the shims outside of the probe. A good trick is to make a V block out of wood, with a deeper
