The error indicates a problem with the CT (Counter-Timer) option. My 2465B, 2445B, 2467B Options Service Manual (070-6864-01), available as a PDF scan from Artek Manuals (no affiliation) describes

Hi Chris, You must be more informative. 1) What do the User & Service Manuals say about this ? 2) What does CT & OC stand for ? 3) Is this just a status alert or does the scope

What is the resistance from the cap side of the fuse to ground? Ohmmeter lead + to the fuse.

The cap measures 48.55 uF and ESR is .26. I'll put this aside and think about digging deeper. I picked up a BK PR-28A in case I go further. I also have a variac and thought of bringing it up to

Hello members,I have not been on in quit awhile and have recently run across an error in a 2456B scope. It pops up after the start up cyle and curious what it means? What shows up is CT test 84 fail

I have the Artek manual - it's searchable, too :) I will check c4006 at some point - thanks!

The 465B is a fine analog scope. Ok, first, the black soot is just that. It is attracted by the high voltage field around the red cable. It is just mostly carbon exhaust. The fuse is in the

Hello RogerAs you can see my SA shows a similar or the same problem.I will look at the 100 Mhz TCXO as Jochen posted.I hope this will be the solution.I tried many times to repair it without

The battery in question is the Panasonic BR2/3A Lithium poly-carbonmonoflouride with a nominal voltage of 3V. I don't change these out unless they are below 3V.They last almost shelf life which is

I bought a 465B as-is, etc. and thought I could get it up and running and discovered fuse 4508 was blown. I put a 1A in it's place and that blew also. I decided to move this beast off my bench

A hook is a trace that goes from vertical to horizontal with a little curve between. If you could see the whole thing, it would look like a shark's tooth, or a lazy saw tooth pulse. With display

Not sure exactly what you mean by hooks ... This may not be the same but I have seen a few scopes with noise on the trace(s) looking like about one minor div of digital noise randomly across the

I hope someone can try it out. I'm out of town right now. Dave Wise

The 2N5401 might still be fast enough. I suggested it and the BC556 because they are relatively common. The KSA992 is the best of the commonly available and inexpensive options that I found. I was

Hi Gang, I have a 2465 that spends most of its time on my shelf as a "should fix this soon" hanger queen. The problem is thus far, I can't figure out what's wrong with it. If you are showing simple

I think KSA992 is a better bet with 3pf max. Dave Wise

It would not be that dangerous but it would destroy the probe. Follow the refilling procedure described in the manual but make sure to add too much butane and then bleed it off as described to

Sure it makes a difference but it also makes a difference in dielectric constant between liquid and gaseous form. I deliberately used the numbers for dielectric strength in gaseous form. I gather
