All: I may not be a Electronics Genius, but I do know the "sales game". HP mocked TEK's "bells and whistles" because those were the most visible and attractive features, the ones that the

Yes, it's been found a full 52% of all people use that old 83% number, but the newer 87% number is the result of the latest research done on 71% of the population. It's solid science. L. <snicker>

I *have* a 7104 with 2x 7A29, 7B10 & 7B15 plugins. But the 7104 CRT is delicate and difficult and expensive to replace. So my reason for a 7904 is to get the best analog BW I can get without wear

First of course, you have to *have* them.? However, I've looked through a number of 7A19's, and there are special purpose fuses in there to protect the inputs.? I've seen several where the fuses

Dave Brown, I found the NOS DC100A tapes on EBAY. Since these tapes are obsolete (over 20 years) - some of the sellers on EBAY have previously used tapes, some have new tapes still in factory

Dave Brown, There are three ways to interface to the 4041 that I see from the documentation. #1 is the intended case for GPIB instrument tests, likely writing test results to the tape. 1 - AUTO

Dave Brown, Great photo. Looks like you have all the same option ROMs mine has! My plan on creating a copy of the System Verification tape is pretty simple - using the TXT files I posted on github,

As in my previous reply, check for a broken wire in the connector. ed

Dave: I have gone through many of these probes and the most common failure I have found is broken wires in the connector that mates to the amplifier. Second most is issues with the hall effect

Hello everyone. Found this group researching my problem. Non working tds 2014. Powers up, backlight comes on, LED’s come on, does not boot up. Began the troubleshooting steps in the service manual

Interesting story Dennis, thanx for that. René

I think the modularity of the 7000 (and 5000 and 11000) series Tek scopes is a big part of their appeal and superiority over the HP scopes. How cool is it to be able to mix and match plug-ins to your

Using the Plug-Ins designed for the 7104 in a 7904 is like bring coal to Newcastle !! The 7104 Plug-Ins are rather rare and worth a lot more than the 7904 counterparts. 73, Dick,

Reg, To add to Harvey's excellent response, yes indeed most (all?) 7k plugins will work in any 7k mainframe. HOWEVER, there are at least a couple plugins (I cannot recall which ones right now,

:-DDD Know what you are talkin' about! Chris

Oops! I meant that for Chuck, but thank you, also, for prompting that informative discussion!

Hi Raymond! Wow! Thanks for the thorough explanation. I had been wondering about the so-called capacitor "reforming." Bruce

Very interested in how you find those tapes. If they are OK then programming them might be a challenge? I dug out my 4041 and checked the ROMS- photo of the ROM carrier in my Dropbox

Please see interleaved comments: Tell me about that one. I was allowed to touch them.? It's worse.... Much depends on how many channels you need, (most need 4 or less), what the bandwidth needs to
