Hi all, I have been down this route. The 200-3397-00 is the only front cover that fully fits the 2225. Others have the same external dimensions but because the 2225 has fixed front feet, it is

Hello, in case anyone wants to use JWalling's services, I made a few pictures of the installation on my TDS754D: https://www.instagram.com/p/CFmbmA6jWdq/ Sorry for praising him so much, but I am

Hello, ad a) NewScope works best, but is pricey ad b) you can try to fit in a stink-normal VGA LCD with a small front panel. There is a VGA signal source at the back which you can dock into. Tam --

Well so far I have found two cracked bypass caps. They were not visually cracked, but when I removed them they came off in two pieces. In both cases, the lead made a clean break from the plate under

Need one since mine fell apart.

Don't worry too much about the HV, it's most likely going to be good once you set the +55 volts to the right point. There is no HV adjustment, only a check of the cathode bias level (-2450 volts).

Tom, I do not have a HV probe. So are you suggesting, therefore that I leave the +55V adjustment alone? I think I read in the manual that changing this adjustment will require full re-calibration of

Hi Siggi Thanks for that ebay link but I’m guessing that envelope contains floppy disks. So we are back to a Dos machine, isa- Gpib to talk to the unit a reprogram it etc. My tds460a doesn’t have

All the supplies reference to the +55 supply so you will want to adjust that first. Go to the adjustments section of the service manual (section 4-23) and follow the process. If you don't have a HV

Tom, I have the correct manual and measured DC voltages with 115.0 VAC line input through my Variac. Here are the DC voltages I measured: TP 4338 +55V, tolerance +54.62 to +55.39 Reading: +56.94 TP

Thanks Bob. I did not see any problems in that circuit. Now I admit that I am still learning about how these circuits work and often I am just checking voltages, looking at signals and testing

Hey y'all, I've always been curious to see the applications that were available for my TDS784D back in the day. Have any of you even seen these applications, or know where I might find them? In the

Hey Roger, out of curiosity, what did you find? All I found was mentions of options software and this eBay listing (https://www.ebay.com/itm/312205219440). I have a TDS874D for which the procedure is

I have found that F814 (2A) on the LV power supply was blown and continues to do so, possibly because of a failure of Q1195 or C1198 (47uF). My question is how can I get to either of these components?

Which GPIB-USB adapter do you have and what operating system? Vince - K8ZW. -- K8ZW http://www.metalworkingfun.com http://www.hamradio.fun

Dear all, I have bought a TDS784D at Ebay some time ago and had no time to test it. When I finally had time to turn it on, I realized that the display is very faint and the image is out of focus. The

I had a very quick look around and it seems that upgrades on the TDS460A are enormously more complex than the 'type in two lines of GPIB commands' that works so well on the later models. Best of luck,

I also have a 2247A and I can can confirm that front covers are completely different from other 22xx series ones, as would be the one for the 2252 which uses the same as the 2247A. No stamped PN
