Those options are not for 744A or any other A-scope. http://www.hakanh.com/dl/docs/kitinstructions/tdsupgr.pdf /Håkan

The TDS (and DPO) 7000 series seem to be very few and far between on the open market, I think it may be a case of taking what's avaialble rather than being able to pic and choose.

At the very least some kind of shrouded plug/socket arrangement. Something like the fluke DMM leads mean you cant get your fingers in there.

Does anyone know what hardware is required for the TDS744a Options: 2C (comm analyzer) , 3C (Optical short Lambda) & 4C (Optical, long Lambda) ? & where to get this hardware ? thank

I had an occasional image "shear" or jitter on my TDS784D. Recapping didn't fix it, and eventually I discovered that the problem was simply that the connector to the horizontal deflection yoke had a

Hi Jared, I've watched your video on YouTube, it is interesting you have re-designed probably a variant of the DS1486 and DS1250Y replicas. As you might probably know, there is an american person

Are those banana jacks exposing bare metal that is at mains voltage?...... I really think you should rethink that design...

Hi to All, Rather straightforward question. Anybody? Early TDS7000 Series NVRAM's have sometimes a too high current drain. Later ones (like the B-Series) use the DS1245Y-120 Devices. These seem more

I would still suspect tants. Although they usually fail shorted, I've encountered a few that behave in a way that's consistent with what you're seeing. Try replacing them. Cheers Tom Sent from my

This should technically (and already is) in the tek500 forum but I thought I'd take a punt on this site in case there are more watchers here:--- I have a PG506 which was working but hasn't seen much

Hi to All, Many years ago I created on TekScopes a Calibration Fixtures Photo Album including inside pictures of a Normalizer, the 067-0529-00 and also the 067-0681-01 TD Pulser. These days many

I thought I’d share with you the most important piece of my basic Test Equipment, which I designed myself. The Compact All-in-One unit comprises the following: 1. Dim-Bulb Tester / Current

Thanks, just what i wanted.

You can see the internal construction of a similar unit here. Same construction, just slightly different component values is all. https://w140.com/tekwiki/wiki/067-0539-00

Any chance you could make the photo available again please? The link www.hakanh.com/dl/temp/537.jpg no longer seems to work. Thanks, Richard Hogan.

It is a good video. :) I was happy to see you don't need more than 9.5V for the calibration process, means I can use my Tek PS5004 Precision Power Supply for a more compact Calibration setup as it

The horizontal screen jitter could be bad capacitors on the CRT PCB. Might be worth pulling that PCB out and testing a few of the capacitors to see if they are still ok. I have heard stories of them
