Re: HP 8566A / B differences
Hi John:
The 8566 is one of the best spectrum analyzers of the old style I've used. For some info about a system I designed and built with an 8566B see:
The disks that came with the 8566 are in a non PC format (the PC was to be introductd years later). They can be read and copied using HP Rocky Mountain Basic workstations that are 68000 based, or maybe by one of the PC clone HP Basic programs, see:
Computer languages for instrument control
HP-IB Controllers
The newer SAs use DSP instead of physical IF filters and can achieve a tremendous improvement in sweep time for a given RBW as well as offering much narrower IF bandwidth. For more see:
- HP/Aglient 4395A combination Network, Spectrum & Impedance analyzer.
Have Fun,

Subject: HP 8566A / B differences
Can anyone describe the exact differences (specs, features) between the
8566A and 8566B analyzers? I'm trying to determine the degree of GPIB
software compatibility between the two. I've recently had my hands on an
8566B, but have no access to an 8566A for testing.
Thanks!

Re: HP 8566A / B differences
Hi,
Mike --
?
I only
had the chance to spend a few days with the 8566B, but I was definitely
impressed.? It is about 12 dB 'hotter' at 10 GHz than the Tek 494AP I
normally use, and the 1-3-10?resolution bandwidth scales have a real
usability advantage over?the Tek's decade steps.? The display quality
is also light-years ahead of Tek, in that they implemented a serious
high-resolution?graphics display instead of using a
warmed-over?oscilloscope?interface.? On the other hand, the Tek's
control panel is a bit?nicer to use due to its 3-knob design, and its
signal-counter feature has come in handy many times.? I ended up keeping
the Tek over the 8566B for those reasons, and because I'm just more familiar
with it and have limited space in my equipment rack.? It was a close call;
the 8566B is one hell of a nice?piece of gear and I imagine the -A model is
no different in that respect.
?
I did
have a chance to add 8566B support to my GPIB plotter emulator app, and one way
you (and other HP analyzer owners) could help is by seeing if it works on your
8566A as well.? This is at
-- the easy way to test it is to unzip the files and run "7470 18" to see if it
can grab a plot from the analyzer at GPIB address 18, or wherever you've
configured it.? This *should* work on an 8566A or an 8568, but again,
nobody has tried it yet.
?
My
understanding is that the 8566B used a 68000 CPU (pretty exotic stuff in those
days; they were right there on the leading edge along with Apple's early Lisa
and Mac machines), while the 8566A used a different, more proprietary
controller.? But I don't know if that translated into any real
functionality differences, or if the RF performance is any difference.? I
don't know if the CRT is any different, or even if my 85662A display section had
a "new"-style CRT or not.? This was the first one I've
seen.
?
A GPIB
programming manual for the 8566A would be handy, if you have that in .PDF
format.? It would tell me a lot about what differences there are between
the two models.? Agilent's site lets you download
the 8566B manual, but not the 8566A manual, as far as I can tell.?

Dear John,
? I was
particularly interested in this question since I've been shopping for an HP
8566B for some time now.? I came to the conclusion that I simply cannot
justify the expense of this fine spectrum analyzer for my non-profit ham and
experimentation? use.? I did however, find an excellent buy on an HP
8566A which I just received yesterday.? It is was certified with a NIST
cal prior to sending, so I have reason to believe it to be in fine working
condition.
?? I had accumulated manuals for the HP 8566B, and
verification software on both 3.5" and? 5.5" floppies? (if you have
the HP computer interface to use them - I can copy the 3.5" for you).?
I've been working through the "getting familiar with.." sections of the manual
for my "new" unit and am totally amazed with the ease of use of this fine
piece of intstumentation.
??? Now, coming around to MY
interest is your question.. I'd like to know what, if any, differences are
there between these two machines besides some expanded HP-IB commands?? I
know that around 1984 or so there was a newer CRT used in both units (was
there was there a production overlap?) and I know that there was an A => B
Mod Kit that included a new board which replaced an older board that had to be
removed.? Other than that it appears that the basic machine functions and
specs was the same.? Are you able to comment on this?
??
Is there any way I can help you?? I know NOTHING about HP-IB other than a
little I've read.

HP165x Inverse Assembler toolkit and 1651B pods
Hi,
Has anyone managed to get the IAL Downloader included in the HP 165x logic
analyser inverse-assembler kit to work? I've tried it on three different
machines, and IALDOWN keeps dying with an "Integer divide by zero" error
before downloading the IA to the analyser.
Also, does anyone know of a source of grabber probes, pods and
pod-to-analyser cables for the 1651B?
Thanks.

I’ve been repairing a 400D AC voltmeter that followed me home
from a hamfest.? I think I have it working, but I have lingering
suspicion about the stability of the 4-tube “op-amp”.? I don’t
quite have the math anymore to do a pole-zero analysis with
any confidence I’d get it right, so I’d like your wisdom and experience.
If I put it on the 0.3V range and give it a 1.5V step, the Output
terminal presents a damped sine wave.? Initial amplitude is
0.5V (note: I’m a bit hazy on this) and frequency
is about 4Hz.? It damps out in about 6 cycles or 1.5 seconds.
Refer to the schematic in the 400D manual, available for free
at BAMA.? The only low-frequency breakpoints I think are of interest are:
1.????? V3 cathode, (Zk + R122) * C105A.? R122=2.7 ohms, C105=1500uF.
I don’t remember how to calculate cathode impedance Zk so all I can say
is that this one’s a pole at something much less than 40Hz.? For anyone
who’s got the data, the tube is a 6CB6 at about 10mA cathode current and
about 120V on the screen.
2.????? V4 cathode, same thing.
3.????? V3-V4 coupling, C24 * (R36+R37).? C24=2.7nF, R36=3.3M, R37=2.7M.
This is a zero at around 10Hz.
4.????? V4-V5 coupling, C26 * (R46+R118).? C26=20nF, R46=680k, R118=1M variable.
This is a pole somewhere between 5Hz and 12Hz.? R118 is the LF gain adjustment.
It works counter intuitively: as you decrease R, yes the open-loop gain falls,
but this is overshadowed by the increasingly leading phase which reduces the
feedback.
5.????? V5 plate supply, C30B=20uF, R51=3300.
This is a zero at 2.5Hz.
6.????? V5 output, R52=10k, C32/33=4uF.
This is a pole at 3.5Hz.
All the important resistors are in spec except the 2.7ohm ones in series with
the cathode bypass caps (they’re about 30% high), but I figure they’re swamped
by Zk.? C105A has increased to 2000uF.? None of the paper caps are leaky.
All the DC voltages are near spec.
Is it possible that C30B has increased, moving its zero too far away from
the C32/33 pole?? Or maybe the C105A pole is reinforcing the C32/33 pole?
Comments?? Insight?? Clue? J

Dave Wise

Re: Stubborn Allen Screws
Mike,
since you would most probably need new screws afterwards anyway, here
is something that worked for me several times.
Just glue your Allen wrench into the screw with superglue (cyanacrylate (sp?)).
Take care no air bubbles build up. the gap between screw and wrench must
be completely filled with glue. Make sure not to move the arrangement until
glue has dried. Once the glue has dried carefully rotate the wrench until the
screw (hopefully) comes loose. Once the screw is removed you will want to
get it off the wrench. Hammer gently (or not so gently) on the screw until
the glue breaks and screw can be removed from wrench.
However, if it doesn't work satisfactorily I'm not going to send you
new screw, knob, hammer, workbench, fingers... :-))
Sincerely,
Andi

Re: Stubborn Allen Screws
You might want to try Torx screwdriver. There is a good chance that lobes on
screwdriver would bite into hex pattern; a little tapping on screwdriver,
while knob is supported on hard surface, might help that bite. And do not
forget that a drop of Marvel Oil (or any other type of penetrating oil) into
screw hole would probably loosen screw enough to remove it; socking for at
least a day is recommended.
A second tack would be to try grooved Allen wrenches. I would not know where
to find them, never seen a whole set, only leftover from sets. Once that I
tried, seemed to work quite well.
Also, a metric wrench might make an oversize one, you have to convert
dimensions.
Before using any Allen wrenches, inspect tip of the wrench. Sometimes, those
tips get distorted and worn out, so you are operating an undersized wrench.
Tips can be restored by grinding off the worn part; do not forget, wrenches
are heat treated, so do not overheat them on the grinder.
Best of luck,
Miroslav Pokorni

Re: 5245 counter service manual
Greetings from a lurker and test equipment junkie :-)
The USM-207 is not the same as a 5245. I have had both and I expect
the circuitry probably isn't even the same. Although I didn't check
the manuals when I had the equipment.
The -207 I had did come with the 500 MHz converter, and I think there
may have been others available, but I never found out for sure.
Back to lurking.

Re: 5245 counter service manual
-----------------------------------
Dave,
The only version of the HP 5245L that I've found on the LOGSA site is called the CP-772A/U (and maybe also the CP-772/U), which appears to be an H96-5245L.
On the LOGSA site, they have only the parts-list manual for the unit. There are two other TMs for it that are NOT on line, there. Their TM numbers are listed in the parts-list manual, which is TM 11-6625-1682-24P.
The downloadable parts manual, unlike many of the other LOGSA parts-list manuals, DOES have detailed board/component-layout and exploded view diagrams, with lists of part numbers. But for component values, you either have to decipher them from the part numbers or have a copy of the Federal Logistics (Fedlog) database.
According the the Fedlog database, the 5245M is called the CP-1049P/U. But I couldn't find any manuals for it, on LOGSA, searching titles for CP-1049 and also searching by its NSN/NIIN numbers for the two 5245M versions listed.
Good luck!

Tom Gootee

Is USM-207 the correct designator?
From a quick comparison there seem to be some quite significant differences

be much use for a 5245L.
