Commenting on your photos is not easy because we don't see the whole story. The V-A, H-B picture showing the pulser output looks like what I would expect. On the "20 mV 50 ps" picture with the fast

I would like to acquire a Type 506 scope with 9A1 and/or 9A2 plug-in. Prefer one that shows a trace! If you would like to get rid of one, please advise as to price, condition and location (I am in the

I have a DM5010 I am not using, and would be interested is selling or trading. I have changed the battery and cleaned up very minor leakage (no repair to the boards if I recall). It does need to be

Yes, I’ve replaced them quite often in my equipment, just for good measure. But I can’t recall seeing one in the 7723. I’ll open it up this afternoon.

Ok. Thanks all. I will review as much material as I can. Happy to know that the unit is working as it should, and at some point it was properly calibrated, has the cal seals intact, albeit from 20

Dear Leo, bonjour, bravo pour le achat ! I have had 2465, 2465A and 2467B back to early 1990s. great scopes with many interesting options, most need PSU recapping and in B version A5 SMD CAP

Hi Leo, Indeed with Heerenveen, Guernsey and Japanese production there is no comparison listing as far as I know. Board Numbers (e.g. 671-0965-05: A5 Controller Board) are more practical. With these

Here's a link to a general manual from Tektronix, on diagnosing scopes. https://www.sphere.bc.ca/test/tek-parts/troubleshooting-scopes.pdf

I've also an AM700 that works quite well, luckily. The seller even brought it to my home to make sure no damage!! Only problem is a strange behaviour in monitor mode, but I never use it. Have a scope

Hi Andrew, if you send me a PM to mgrbosma@... I can send this manual to you via We Transfer. However, It will be only from Tuesday 28 December 2021 onwards, unless you can respond within the next

Excellent, the calibration on the 577 should converge now. Looking for good news. Zen

If anyone has any that are toast (DM5010) let me know I would be interested. Uncalibrated is fine. Zen

So what's going on when you get the scope into X-Y mode? The screen lights up like a storage scope with the intensity up too high (the whole screen glows an even bright green). What we expect in X-Y

Picked up an SC504 (TM500 80MHz dual-trace scope). It had been dropped on the knobs. The main problem was in the time/div switch area. Both the Var and Time/dir knobs were shattered and mostly

Interesting that the screen un-blanks and lights up when you set the sweep speed to X-Y. This mode causes the Z-Azis logic to unblank. See if you can find out why it's (almost) always blanked. I

Correct. Precision of delay time in cable between pulser and sampler isn't important. Raymond

You are right in that the risetime is important but you normally can't control the risetime of the cable/transmission line you're measuring. Risetime of pulser and cables determine the steepness of

Just to follow up on this thread, With Ozan's help, CR430 was bad. The originals are 1S2200 (10mA, 8pF max) and I replaced it with a 1S2199 (10mA, 2pF) and the triggering is working now. After fixing
