Re: 7000 test/cal module(s) and backplane breakout board.
I'll probably create a project page somewhere with the eagle files, theWhat's the height or rather width you used for your finger connector?
I had a similar project for debugging purpose (https://github.com/anotherlin/tek_7k_ext).
However, I didn't add "margin" on top and bottom, so I have to manually align the extender when inserting.
And so far, I was not able to find mechanical data from Tektronix documentation
