What about the somewhat newer TSD2000 and TDS3000 series? We had a lot of them at my previous job. They are not quite as fancy, but much smaller, lighter and responsive. They can have at least RS232

Hello Folks, need to advise on some things related to the TDS5xx series for buyers. First of all, only the D models can do GRADIENTED DPO - on classic InstaVu scopes, frequency information is

Good info Harvey! And the truth of it is that it's really good to have both a 1502 and a 1503. The 1503 was intended for looking at much longer distances and it quite useful for stuff like long runs

Jim, Did you manage to extract the GPIB card from the faulty SA? Thanks, Martin

To be fair, Joel Koltner has been dead, for years. He was a regular on news:sci.electronics.design and other electronics newsgroup for years prior to his death. Michael A. Terrell

If you don't mind outsourcing the repair, let me recommend Jay Walling: https://www.instagram.com/p/BkpHaVJgsZr/?utm_source=ig_share_sheet&igshid=1jpdh3tjkxm3v His display works perfectly in my

Many thanks George. I did wonder if the pattern might actually be due to velocity mod on the X-deflection, which is tantamount to the same thing. I'll investigate and report back. John

Yea I noticed that too. If you have to ask, it's too much. I'm not even prepared to put $230 into the TDS544A at this point, but thanks for the suggestion. ST <wyzkydd2358@...> wrote:

Joined this site a short while ago to get info for the 2215 scope my friend gave me. Got interested in other models and then decided it might be fun to get some more and see about fixing them up or

I do understand that,? my reply was more directed at fellows with the color CRT versions,? but for the 540 and it's ilk, mayhaps you could at least select the color of your monochrome.? Regarding

Several things about the TDS540, from what I've understood. One is that the BIOS is not smart enough to write in color, secondly is that IIRC the graphics chip is wired so that all outputs are going

John, I had the exact same pattern and it turned out to be noise on the AC mains. Turning off fluorescent lights did wonders to reduce it. The collector sweep comes directly from the AC through a

So $230 bucks worst case on top of the cost of a TDS784D vs a Siglent. I know there's not a lot of comparison other than you stick a probe in there and you get a wiggly line interrupted by a massive

Case in point: http://www.simmconnlabs.com/1401/2606.html I used one of these kits to bring my TDS784D back to life (dying CRT, what else is new?) The result was nothing short of amazing. Happy

There are people marketing solutions for the dim CRTs on the old TDS scopes. As far as I know, all use the rear panel VGA output to drive a modern display mounted where the CRT used to be. A little

I wonder if an OLED screen is available in the proper size.? Those are nearly as good as a color CRT in color "pop" and good dark black reproduction,? and much better than the shuttered CRTs in

Are there locks on the drawer slides that drop into place when you pull it all thew way out? If so you push in on them, while closing the drawer. Michael A. Terrell

After many years, I attempted to open the drawer. I was successful, but it didn't open smoothly and I cannot close it now. Looking underneath, there is a plate covering everything but the last 3 1/2

Many years ago, I was playing with transistors when they (almost) first came out. It's a learning process. I've got electronics that are old, but I've decided to concentrate on mostly the solid state

I've seen several scenarios. One has a tantalum capacitor directly across the power supply, either on the main board or on an auxiliary board. A de
