My mistake: HP1740A. I get the impression vintage TEK scopes are ten times the price they were ten years ago, and now rare. My HP1740A was from a recycling centre for next to nothing, just needed

Hi Nick, It doesn't help you any further, but in a rather tricky way I managed to create a horizontal gap in AVG waveform acquisition. And indeed a (dotted) linear interpolation line between the dots

Raymond: I only need 1 Lemo 4-pin plug. How much would it cost me to have you send me one? How would I pay for it? Here is my address: Gary Bosworth 139 E. Shrode Street Monrovia, CA 91016 Cellphone:

I was given an old 547 that was set for scrapping. It that had some high voltage issue. The tubes were partially pulled but it seems intact otherwise. I'm located in Austin Tx if anyone wants to come

I did a search and somehow this one slipped through the net: https://www.electronicdesign.com/technologies/test-measurement/article/21137778/the-tektronix-function-generator-teardown FG502 Teardown

Look up " james_s <https://www.eevblog.com/forum/profile/?u=127611>" on EEVBLOG. He has a much better solution. i would show you a picture, but I don't know how in here. 320041677522-0001@...>

Don't know where "right below.." is. I've taken the liberty to introduce the term "Replaceable Parts Registry" on Tekwiki for those who don't know the term "RPR" (yet). Both terms give ahit now.

Oh, interesting. I assumed you were talking about the 5VD, which is the main switch-mode regulated supply that feeds all the digital logic. You're talking about the linear regulated 5V supply. Same

I wouldn't even think of interfacing the 1S1 with anything other than a 530,540.550 series Tek scope. It's a complex interface, involving not just the connector but several different power supplies

You probably tried AQS because I pointed to that. Something very strange is going on with AQS in my 7854 (or with my brains?) AQS worked at 0.5 ms/div but not at 0.2 ms/div and faster. OK. Later on I

No pictures this time but, (YET AGAIN) it's changed behavior, now its getting AVG acquisitions (mostly) fine (As in not erroring out but still occasionally having some weird defects to the wave but

Hi, I would first check the power supply. I'm not a big fan of "the universal internet method of fixing everything", that is indiscriminately recapping stuff, but in the case of the 24xx family DSOs,

That's the purpose of the common parts catalogs of which we also got a release and are posted on TekWiki. I don't know if they all are there but they can be scanned and uploaded. Dave

The 1S1 is a fine sampler when it works. It is however what I would call "high strung". It has a way of failing in interesting and completely different ways all the time. It is also not easy to

F269 is soldered but I was able to clip onto L256. A minor amount of ripple that only changed by a few millivolts when I added a 2200uf cap across it. No change when I switch below 200ns. The 5V

Isn't that an HP 1740A 'scope? You won't see the Reply icon unless logged in. Raymond

Hi Dave, My comments embedded That's true when looking for Tek part numbers. The added value of OCR here would be *reverse* use: "What's the Tek no. of a 2N4275?" Unless the reverse list is available.
