Hi all, I have a TDS620B here I'm doing battle with. After repairing the power supply, Iit seems to be failing SPC on channel 1. I've tried replacing the hybrid modules with spares, to no effect, and

That guy linked on tekwiki is me. :) I've uploaded the battery replacement document to tekwiki, so take a look. I have some spare bare PCB's as in my video if you want to build the rectifier upgrade i

Hi all. I have a number of faulty power supplies from the TDS500/600/700 series of scopes and I'm looking for the schematics if anyone knows where I can find them? I already have the usual schematics

To answer my own question as I managed to source an original part, the resistor is 49.9 ohms between the centre pin of the BNC and shield/GND (as I suspected).

Hi all. I just picked up a P6247 differential probe, but it is missin a few accessories. I want to build my own "BNC to probe tip adapter", which looks like not much more than a BNC socket on a PCB wi

I think you misunderstood. I have flipped the footprint for the NorComp part as well as placed it on the opposite side of the PCB, it is a different Gerber with different layout to my original file fo

This one needs to be on top pf the PCB, it has a riser card that connects perpendicularly so it's position is fixed. If it were a flex cable, it would be ok to bodge, but as it is connecting to a rigi

Unfortunately the Champ part (1-1734099-0) won't fit as the staggering of the pins is opposite to the footprint on the PCB. Here is the underside of that part: https://i.imgur.com/DGVLdeO.jpg Here is

Tracked it down to Tektronix part number 131-4619-00, 3M part number 91100-1201BP. https://www.mouser.jp/ProductDetail/3M-Electronic-Solutions-Division/91100-1201BP?qs=pxWKQutMSmprHMNm7tgF9Q%3D%3D Now

Hi all, as part of repairing a couple TDS600/700 series scopes, I need to source a few connectors. Does anyone know what this connector is and where I can find some? I can't see any markings on it to

No worries at all, it doesn't take me long to alter the footprint of that one part. The file is uploaded to the files section: https://groups.io/g/TekScopes/files/TM500x%20GPIB%20Adapter%20Board Be aw

I just made the gerbers tonight actually. They are a direct copy of the Tek part (slightly modified to use the specified GPIB connector) so they will work fine. If you want to use a different connecto

Here's the photos and a couple gerbers of a reproduction board I whipped up, copied almost exactly from the board in my TM5006. There is a PCB and a rear plate. Just order the rear plate as usual for

I have three TM5006 mainframes here, I haven't checked if they have the GPIB boards, and I unfortunately can't offer any boards for sale, but I can take some high resolution photos to upload to the Te

Ok, Thanks to Bruce, I now have all the Field Adjustment software I'll ever need. :) I'll add them to TekWiki soon. If anyone has any other software that was available for these scopes (like 063-1134-

You could also upload it to the files section here. Regards, Jared

Thanks! But it tells me that the daily download limit has been reached. Is there another way I can get the files from you? Thanks, Jared

Hi, I have a growing collection of TDS scopes that I am restoring etc. I'm looking for any software that anyone might have on their hard disk option, or anything on floppy disks that they can send me?

If you like, I can upload the files to the relevant place on tekwiki. Regards, Jared.

Well, count me surprised.. After pulling out R50, R51, R52 and C50 to test them (all well within spec) and reinstalling them, I am now getting the expected 8.8V at pin 6 of U50, and my output is now l
