My 2465BDM has a GPIB option. I'll never use it; all my other instruments either have no external connection to the world (my computer) or use ethernet. Relative to heat and energy consumption would

Hi Dave, I found this book you recommended under the "Concept Series" in tekwiki. It is very helpful and easy to read. Another article, a little more advanced, is on www.tek.com. It goes beyond

Hi Dennis, Hi All interested in TekScopes and Groups.io The email truncation, in a post, is probably, but not necessarily, the Groups.io settings for TekScopes. You could see the following, 2 links

While you are inside the scope, or at least put it on your to do list (along with a full recap of the power supply as well) might want to visually check all the MB2501 fast recovery rectifier diodes

Very good thread suggestion on 2465B I didn't know they are so similar to my late 2445B 200MHz version

One easy trick that may or may not be helpful is to take a video of the screen as you use the exerciser routine to step through all the 256 visible values. If you lose the calibration values in the

from Tim P (UK) I read somewhere (can't find it now ) that there is a mod to enable a CA plugin to use the A / B alternate sweep feature of the 547 scope. Anyone know how it was done? Hakan ? (I

It is actually 4 electrolytic caps in total on the A5 board that cause the corrosion and need to be replaced. The 4th cap (33uF 10V) is located on the top right side corner of the board (along the

Hi Roger, I haven't had a go at cleaning the cam-switches contacts, because I took your advice and re-seated and cleaned the pins of the ICs. The DM502 now seems good. There was a little hiccup when

Well I’ll be dipped, it turned out that one end of the main delay line was loose and was preventing the vertical circuit from working. If anyone ever has similar symptoms, check for that!

Hi all, yes, the 2215A problem is solved... Again! After I fixed the trigger issue it ran happily for about an hour, after that it went PHUFF!! For no obvious reason the power supply went, like

I have a great deal of sympathy for that attitude. However, I do replace old RIFAs on sight, particularly if they are across 230Vac lines. I've had two 24x5s imitate the old indoor fireworks, within

Only one company is associates with bad IC sockets - that is Texas Instruments. Their sockets are easy to find by removing the IC because the TI logo is stamped underneath the IC in the middle of the

So C693 has been replaced with an aluminum electrolytic so I can tell if it pukes, and because I had one leftover from the 2465 repair. So now the +/-20V and +5 are up and running. Unfortunately,

Sorry, I just noticed, I'm not used to this groups IO thing.

I wholeheartedly agree. I'm so glad I was pointed to this group because people who suggest blanket swap of capacitors are not my sort of thing. I prefer to diagnose the problem by doing measurements,

Hi all! New to groups, so bear with me if I’ve messed up something. I have a Tektronix 2246 with some very strange symptoms, it’d be great if I could have some help diagnosing it. Basically, all

Hi David, Anything that will increase the number of eyeballs looking at the datasheets will improve the chances of finding the answer. More people will be willing to help if you make it easier to

I have no idea why this happened. Can anyone else offer an explanation? Dennis TillmanW7pF

Hi Carl, Thanks for the link.I like how the author compared the effect of each thing done to the raw sampled data to make it more believable Has anybody else wondered why the author, Israel Banini,
