The schematic for the P6131 probe I use on my 2465b. I can't figure it out! T-coil

Lawrance A. Schneider

The schematic of which I write is in the probe's manual. It uses a T-coil to extend the bandwidth. With all the discussion about attachments, ... Further, I'm not sure how to post a photo of the schematic anyway; if someone knows how and would like to post it I can send it to whomever. I've found a few urls for the T-coil: Mr. Ross seems to have brought it to TEK again, Mr. Ross seems to have brought it to TEK

Back a half century ago, when I worked with Hermit Polynomials and Dirac equations, I could (maybe) handle the above references; at present, I'm having a very hard time. In any event, it is more than this second year etc student can handle.

Does anyone have a more clear explanation of how the damn T-coil works?

In my own post, 'etc student' was to have been 'EEC student'.

Sorry to be in a learning mode relative to posting my own posts.

I have up-loaded to the photos area the schematic to the P6131 probe. No mater how I re-draw it, I can't make sense of it.

AND!! That should have been "ECE student".

Take a look at page 25 of the following document:

It discusses a probe with T-coil termination.
