What an excellent resource this thread is on 24xx scopes. I always wanted to get a 2465B, but shunned it a bit mostly to the part of having to deal with the Dallas RAM module replacement, and reading/programming it, etc. I am very experienced in electronics, but have not done much memory chip programming, so this will be pretty new to me. Now thanks to this great post I am very close to having all the info I need to go ahead and get one of these great scopes, and a list of all the post-purchase things that need to be taken care of. I currently have a Tek 2247A 100MHz as my main scope and I am very happy with it, I did all the required/recommended internal update work when I got it back in 2012. But.. of course one cannot have too many scopes, right?
(I also have a 222 and a 2013A).
I have been reading this post now for several hours straight from page 1 and been taking tech notes, so far I'm only up to page 20, but decided to jump ahead here to post a quick question. I have my eyes on a friend's-friend 2465BCT (SN 59xxx) and last callibrated in 2015 which he apparently no longer needs and I am told it is in good shape, although I have not seen it personally yet. My question is, what are the differences of the BCT version over the plain B type? I see that both are 400MHz, but I am not sure what the advantage would be to get this BCT type. I understand the CT part means "Counter Timer" (?). Does that mean that I can take automatic frequency/Time readings on any waveform in the same way I do it with my 2247A (as well as voltage readings, etc) which I find extremely useful features and would hate not to have them available on a 2465B (or BCT variant) scope.
Could one of you very knowledgeable members please explain what are the advantages or disadvantages of the BCT over the plain B version? The scope would see mainly hobby bench usage, but I would definitively want to know what I would be getting into to ultimately help make up my purchase decision. I looked around for a manual of the 2465BCT but so far only managed to find OM/SM manuals for the 2465B and 2467B in PDF format.
Thanks to all the people that have already contributed to this post over something like 6 years now. Simply amazing!
Well, its back to page 21.
