Service Manual for a 5223 w/ Opt. 10

 

I acquired a 5223 in order to test some plug-ins (5A48s and 5B25Ns), and I guess I didn't do enough research before I bought, because I wound up with a 5223 Opt 10 (GPIB) and TekWiki says that there are different manuals for the Opt. 10 scope than for the non-Opt. 10 scope. The manuals that I see on both TekWiki and on eBay indicate that they are for non-Opt. 10 scopes.

Does anyone have a service manual for the 5223 Opt. 10 that they would be willing to part with?

VR746 is in the power supply to the base of Q754.

Re: High voltage supply T-935

 

Thanks - Cap seems OK, can't find VR 746 (as Tektonix seem to have their own way of assigning groups. Maybe I'd better get better close-up glasses!)
So voltages seem normal - and the fuse is OK. Maybe the Hfe of the transistor is too low - but it seems a very simple and robust circuit.


Re: Anyone Have a Peltola Socket?

 

If a scope is going to be new to you get a 465 or 465b so you learn the functions and what they do. Then in a year pick up a modern scope.
Just my 2 cents


Re: Anyone Have a Peltola Socket?

 

That¡¯s the solution for a square peg in a round hole.


Re: Anyone Have a Peltola Socket?

 

I noticed the "little wings" on the Berg design and I didn't recall those being on the one I have. That's part of what prompted me to wonder if they were interchangeable.

Thanks,

One more advantage of the Berg design is the silicone plug. It is moisture proof
and solder proof. That¡¯s great for washing after soldering and limiting crud
after the wire is inserted.
Take care to remove all of the solder from the pcb hole. The Berg socket is
intended for machine insertion and has a feature for retention in the hole. It
is a snug fit. If the hole is too small or has excess solder, the little
retention ¡°wings¡± will peel up and get sloppy.

Re: Opinion on 'scope selection

 

Sorry for veering off-topic, but I have a room for my hobbies and my other half has a room for hers. The rest of the house is ours.

It works delightfully for both of us.

My room is also my work-from-home office. On several occasions, I've reached for something behind me on a Zoom or Teams call, and someone will almost inevitably exclaim, "I thought that was some sort of fake background! You mean all that stuff is _real_!?"

I think it looks great in my man-cave, but I can appreciate that it wouldn't be appropriate outside of it.

Don't forget parts units for things like HV transformers, power supplies, custom ICs CRTs, FP hardware.

7904, 7103, 2430A, and TDS540A on the bench.? 2430A is mostly backup, 7103 is just in case.? work gets split between the 7904 and the TDS540A depending on rep rate and what I need to do.

(and my wife does gourds, weaving, knitting and the like.? Has two rooms for it.? I get no complaints)

Re: Opinion on 'scope selection

 

The 2465 doesn't have a battery backup, unlike the 2465A and B. So you don't have to worry about a battery that has failed, or is about to.

The two scopes on my bench are the 2465 and a 7904.

Hello--

A couple of questions: will you need to tote the scope

up ladders or many flights of stairs? That argues for lower weight and smaller size.

Also, scopes with built-in data capture are convenient, but make sure that you can find a

utility that runs? on your personal computer of choice.

Hi,
Again - good points to think about - I'm not one to worry too much regarding noise - my wife says I'm deaf, but it's more that I come from a large family.?

I must admit to wanting to keep a THS730A as a back-up and lean towards the 2465/2465A after checking the items out.

I have a few scopes in my lab, including a 485, 7834, 2430, 2465, 2467 with

very very usable and usually more than capable. It's only when I run out of
"slow" that I go to a digital scope (the HP), or if I run out of fast I go
to the TDS784D scope.
You should definitely go have a twiddle of all the scopes on offer, and you
might want to listen to them as well. You may find that the 2465 is more
suitable for a quiet lab than the 2465A, because the former has that
wonderful impeller fan, while the latter has a "computer" box fan.
On the whole, I'd probably go for the 2465 or the 2465A, though the THS730A
is interesting in its own right, as it has two isolated channels. Assuming
it comes with suitable probes, this can be a nice feature to have on
occasion.

Barry,
The patent shows a socket that was not widely used. The Berg socket was in
common usage by mid 1970s. Early transistor sockets (a.k.a. ¡°mud¡± because of
color and crumbly structure) were being replaced with Berg sockets during that
period as well.
There might be a few variations on the Berg socket length but they are indeed
¡°miniserts.¡± Tektronix would likely have used only one type.
I think Berg was the first owner/manufacturer, followed by DuPont, Amphenol and
FCI ( not necessarily in that order).
You can scavenge from a Berg-socketed transistor and just solder the transistor
in place, or I can send you one or you can get some fresh ones from David P.
