A tool is only as good as it's user makes it. I've been using mine for close to twenty years, troubleshooting everything from monitors, power supplies and floppy drives and from to Multibus boards to Pentium-class microprocessor based embedded systems. I've only recently upgraded to a

2445B when the traces in the 465 developed 60Hz noise - and yes I know it's probably the power supply caps, but I can't be bothered to repair it.

The 465 was NOT a storage scope, although there were versions, 464 &

466, which were.

Of course any CRT has some phosphor persistence, but this is generally not confused with memory. Tek made a number of CRT storage scopes which used "screen storage" which used a special CRT which would keep the phosphor refreshed and hold an image on the screen. The 465 was not one of them.

Digital storage is different from both of these.

The 465 and 465B were probably 2 of Teks most popular scopes. Both are excellent.

my 465 does have a Phosphor Memory CRT. it just that they get a little sucky afrer a while they don't show a nice even image after a while. and it does hold it the image for quite some time.

465 is a NON-storage scope,the 464 and 466 were storage scopes. Your 465 scope could have an optional long-persistence phosphor CRT,though. But it's still not considered any sort of "storage'.

Any chance that you mean 564? The 465 doesn't take plugins; the 564 does, and has screen storage.

thats my misstake, i have a 464 not a 465. and that does have CRT Phos storage.

Yes, the 464 is a storage scope, as is the 466. One of them was screen storage and one was digital storage, I think. I don't know which was which.

From your comments, I gather that the 464 was screen storage.

Both 464 and 466 are 'screen storage',the 468 was the digital storage scope.

And there also was the much earlier 465 with a very low-performance digital storage option(modified product?),that looked like a DM44 piggyback module.

Okay, but what's the difference between the 464 and the 466?

I don't think that option shows up in any catalog. I've certainly never come across any mention of it before, except possibly from you.

I've always been surprised at the various non-stock options that Tek could come up with, however.

466 has reduced scan,giving a higher storage writing rate.

465 etc have much greater dynamic on screen range than any? digital scope approx to uV in 10V. Can see rf at low level on audio which would otherwise require spectrum analyser.
