Have you checked the A6 board Of the front panel From experience I when i fix my 2465 Failure in one of the diodes can cause such a problem You can also do a pot test Exercise 1 And check

When I first got the scope, it was good, but as I recall, the fuzz just slowly progressed until it was there always. That seemed like a capacitor problem, so I started there. I removed the A1 board

Have each of you looked into the condition of the SMD electrolytic capacitors on your spectrum analyzers? In the few examples of these spectrum analyzers that I have worked on, I have found a number

You may want to check all readily accessible hardware mounting and grounding, particularly around the delay line. If the hooks are constant, then they must be leaking into the circuit past the

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
