Dennis, I had just recently finished reading Barrie's Biography in the IEEE SSCS NEWS from 2007, a supremely fascinating story. This would be a good starting place for anyone wanting to learn more

Hi all, I'm new here but some of you may know me from the eevblog forum and the TDS floppy nvram dump scripts. Currently I'm looking for some good soul who would be willing to share very detailed

Two things: - I've checked a TDS694C board here and there are two paths going into the analog preamp/mux (the row after it are the ADCs). The scope selects one or the other path according to vertical

I guess that means I have to have lunch with you in 2 weeks. Sigh! Dennis

Ill have to search his history. Sounds like an amazing guy. Thanks

I lost a friend! We lost a giant analog IC designer! Barrie passed away after a fall yesterday. I had lunch with him in October to give him a 6-gun CRT to add to his collection of unusual CRTs. At

Hi Jack, you didn't give up, did you? Albert

Tim P, I would like to learn the cause and resolution of that problem myself. Perhaps Mr. Wilson could expand on the actual cause of the problem and his solution? Thanks! -- Michael

from Tim P (UK) re the 5111 - what was the problem with the -30V ? I have a 5441 with a low -15V (11V) and a high +30V (+38V) The LVPS in the 5000-series seem to be very similar. I would be

Well Stated Chuck! -- Michael Lynch Dardanelle, AR

Hi All... Given the expense of the SG5030 Sig. gen. & leveling head ($2000 +). I am looking at doing a project to create a precision Peak 2 Peak Voltage display 'Head' for the output of my SG503. I

Tektronix didn't lose their way, they lost their market, and the old guard couldn't figure out how to cope. Reagan spent the Soviet Union into bankruptcy, and then shifted gears into reducing the

Continuing on this 576, I removed the four Printact relay armature assemblies, and found that the gold plated contact pads on the board were quite pitted on the two uppermost units. I did not expect

I never met Stan personally but have his book and also had email and snail mail communications with him. He was a real gentleman, a fount of knowledge and very helpful. RIP. Morris Odell VK3DOC in
