Re: Scoping the Power Rails [8566B]
Jinxie, Your spikes do sound a lot like what you'd see from excessive probing inductance caused by a large loop area from the ground lead. One simple test I often do to determine whether my probing is

Difference between HP 10501A/10502A/10503A and 11170A/11170B/11170C BNC cable assemblies
In the 1983 catalog, HP lists 2 different sets of BNC cables: the 10501/2/3A series and the 11170A/B/C series (p. 640). Both are listed as using 50ohm coaxial cable. The first series says it uses

Might not be a bad idea to look up and review Bob Pease's article(s) on this. Grounding was a particular concern of his and he wrote several very good articles explaining the concepts. Cheers! Bruc

Re: HP8903A project
I have three 3488 switches and a selection of plug ins. I recently bought a well loaded 3488 at a pretty good price from Ebay in the UK. I would love to be able to buy some of the connector blocks for

Re: Scoping the Power Rails [8566B]
I'm not too sure what Harke means. I don't see what shorting the tip to the ground is going to achieve. I'm probing A17 and A18 boards and there is simply nowhere other than nearby aluminium chassis

HP8903A project
Here's a link to a blog of mine elsewhere which I hope some on this group may find interesting. It covers some (initial) work on the 8903A and my take on yet another USB - HPIB interface.

Re: HP-8753E Reading HPGL Files
Hi Steve: I have Jon's Software. I use it for some older Tektronix and Advantest instruments I own. I always thought it was designed to be used with a GPIB interface. Let me load this up, and see if I

Try KE5FX. A Google search yields the first hit at his GPIB toolkit, which includes a reader that will take an HPGL file and display it under Windows. Steve Hendrix

Jinxie, Have you measured with the earth clip directly connected to the probe's tip? Close to the area you are looking at. You will be surprised what you see. As you say you measure the same at any
