Scanned or a copy is good enough.

Nice and neat.

You must have thick plastering for the lathe not to show up poking out
of the wall!

Does enybody know, where can I find "Agilent/HP 8754A Network Analyzer"
operating manual? I need to download it, but I can buy it also.

Was it a wood lathe or a metal lathe?

I found this unit at the local landfill and it has an output, however
the panel meter which doubles as a voltage or current indicator
depending upon which front panel switch you push in, does not indicate
anything. Does anyone have a schematic for this power supply or do you
know by chance if anything in particular on the rear terminal strip
needs to be strapped for a on board reading? Thanks very much for any
assistance. Lenny Stein, Barlen Electronics.

I do not know of any commercial PS that requires jumpering to get a
front panel meter to work.
Take the case off and check the wiring and most especially, the switch
(corroded, maybe).
Also it does not hurt to check the meter with a battery and series
resistor (no power = PS unplugged).
Assume 100uAFS and set current to near 50uA; if 1mAFS you will still
see some deflection.

IIRC,this is Tektronix' phone number,and they do NOT support obsolete
products.You will get no help from TEK for a TDS420.(unless the parts are
common to current products,which I doubt.)

Can someone illuminate me on the differences between the these scopes
and the order they were produced? In particular, I note an "Auto
Setup" button on the 2246A that is missing on the other 2.

Thanks!

IIRC,Mod A was developed for the US Navy,has a different battery(CR123
instead of coin cells?) for the NVROM backup,and perhaps different
software.I'm not 100% certain of this,though.

Considering that TEK long ago discontinued support for these,there may not
be anyone who can definitively tell you the differences,unless you run
across the TEK engineer who worked on that project.

Some here may remember my quest for a large-screen X vs Y scope.

I picked up a Telonics 101 10" X-Y scope on E-bay, and was
surprised to find that internally it uses magnetic deflection. The
CRT is about the same aspect ratio and length as a 10" TV tube. (i.e.
it's not long and skinny, like a typical electroscatic scope CRT). There's
a yoke, and two smallish PCB's for HV generation and deflection.

Frequency response is limited (seems to not go much above a few tens of kHz)
but is good enough for my playing around.

Knowing something about Telonics instrumentation, this was almost
certainly intended as a display for a spectrum analyzer. Seems to be
maybe mid-70's vintage.

My question: What are the fundamental constraints on frequency response of a
magnetically deflected scope? Inductance in the yoke would seem, to
me, to be the limiting factor in setting the maximum sweep rate. Bigger
currents in the yoke driver will get you faster slews. There's
probably some frequency (10's of kHz? 100's of kHz?) at which the yoke
becomes self-resonant. Am I missing anything?

Inductance you can manage. I'd think your constraints would be limits on

the driver. With a 10 KV supply, you could get some pretty respectable
dI/dt! ;-)

And of course, since it's inductive, you'll get that famous inductive
kick at retrace.

Go ahead and slap together a couple of oscillators, and see what she'll do!

Have Fun!

whatever the deal, you wont get far with it.

In my case, I can just scale the max frequency down without any pain.
After all, I am using it strictly in X-Y mode as a display for an
analog computer where I get to choose all the time constants.
*I* control the horizontal, *I* control the vertical .
It's wonderful to have a big CRT to do this with.

Signal measured can of
course be 20x the sweep freq, past that you can use an envelope
detector... but you still will never make it too far on mag
deflection.

That's my original question: what's the fundamental limit on frequency
response with magnetic deflection? We have V=L dI/dt (more of a slew-rate
limit than a bandwidth limit, until you start insisting that the picture
fill the whole screen!), but is there
anything else? When does the self-resonant frequency of yoke coils
bite back?

Just a wild-ass guess, but I'd surmise that the self-resonant frequency

of a deflection coil is so high that it's irrelevant at any frequency
where you could get enough current through it to actually deflect the
beam usefully.

Have Fun!

What exactly was a Bsm connector? Any relation to a SMB?

Are there any adapters to currently used connector series?

Is there any reason anyone can suggest why I shouldn't just replace it with
a small RF connector like an SMA?

BSM is a well-defined standard, but I can't tell you exactly what it is.
TEK used 'em cause they were small. There's a BSM to BNC adapter.
The TEK ones have two "tits" for lack of a better word for the latching
arrangement. I once bought a bunch and though I got a great deal.
Turns out that there's a version with three "tits". 'Bout the only
reason to use one is if there ain't room for a bigger connector.
If you've got something that fits, change it.

Might these be similar to the miniature connectors sold my Lemo and Fischer in
Europe? These are small single and multipole bayonet fitting connectors, used a
lot for audio.

Just a thought.
