Bill ,
?????????????? thanks for that information.

I guess there is a very small chance the original cable adapter pair, might not work with a newer instrument, but it seems pretty unlikely based on your usage.

Since these special cables can get to be pricey, it would be very useful to know if we could just patch in a coax connector to an existing cable,if we don't have the official cable.

Does anybody know if the coax tap, is just connected in parallel with one of the wires, so nothing needs to be cut,and if so to which connector pin???
Is there any changed termination/attenuation,?? required for that pin???

This should be relatively easy to test with an ohmmeter, for somebody who owns one and wanted to volunteer to add to the community knowledge base.

The Spec An / Preselector combination does not work without the HSWP connection. There is an error that announces the lack of the connection and the instrument will not go beyond that point.



As far as the two cable types with the different HSWP pickoff, there is no apparent difference in the functionality or effect on measurement accuracy. I had a set of the 8574A cables that had the pickoff on the cable connector side and used that set for performance testing of all vintages of the system when the customer cables were not shipped with the unit.

our time and revenue stream is better served doing the main manuals. I

Here is a proposal as a possible solution. I will box them up and mail
them ( at my expense) to anyone in the continental USA who is

willing to

scan them and post them on a public web site preferably KO4BB.com and
one other TBD. There are at least 500-1000 pages so this is not a
trivial task , nor do I expect it to get done overnight once you take
responsibility for them. You need only a letter size flat bed scanner
and a willingness to to do hi res and gray scale (of photo pages) when
required although 90% of this can be done at 300DPI B&W. If you want to
spread the work around among multiple participants that is fine with me
but you work that out among yourselves, I am only going to ship one box
of this stuff to one address and I DO NOT have the time to even

"manage"

this project.

I am also open to other approaches besides the above.

The flag is raised those of you who are so moved may now salute..If I
get no takers then I will likely at some point in the future get tired
of tripping over them and consign them to be reincarnated as toilet
paper tubes and cereal boxes.

I'm guessing your running this thing in native mode but if you had it
hooked up to the GPIB , then a simple routine could be written to set
the new defaults on start-up. Actually thinking about your request in
more detail the routine could be used to "capture" the current settings
and store them ..then you just run the recall routine on start-up next
time. The more I think about this GPIB is the answer, not to mention
other perks like data retention etc.

Is there a fairly simple keyboard command that will set up the 8920B

I don't know about this instrument, but on my 8720D VNA, if a
calibration state is saved with the name "UPRESET" then it will power
up with that setup. It's a long shot, but you could try naming the
setup you want UPRESET

Max,

I grew up on Heathkit and built a few kits before they went under the first time. I recall building a HW101 HF transceiver, 20 MHz scope, HW2016 2-meter transceiver (my first fully synthesized rig), and a morse code keyer (u-matic). There was also the digital weather station and a digital clock for the ham shack. My dad also built a few Heathkits pieces of test gear i the 50's and 60's. It was all good inexpensive stuff that worked reasonably well.

The first time I used a Hewlett Packard frequency counter as an Electronic Technician back in the 1970's, I fell in love. I also appreciated the Fluke digital voltmeters and Tek scopes. But mostly, I dreamed one day of owning the Rolls Royce of test equipment.

Well, today, it is used and older technology, but it still has the wonderful quality that HP built into most every piece of equipment they engineered and constructed.

Best of luuck with the upgrades. I hope to join you in retiremnent in a few years!

Regards,

Joe

Subject: [hp_agilent_equipment] Re: counter

Hi Max,

I have refurbished many of the 5335A, and several 5334A/B models

over the

past several years. There is good news and bad news on how repairable
these models may be. The bad news is that these are getting fairly

long in

the tooth, and some parts are reaching the "unobtainium" stage.

The good

news is that there are many of these counters still on the market,

and if

one shops well, one may find a good "donor" or two to fix the

first unit

for not too much money. This method is actually how I got started
refurbishing HP gear. I bought a 5335A Counter for my setup, and

the odds

were against me in that it did not work. The needed parts were not
available through normal suppliers such as Mouser. So, I boughts

another

unit, and it worked! It took two or three more units to find one

that did

not work, so that I could make it a donor unit. By that time, I had a
pretty good inventory of spare parts accummulated...

My experience is that only about 10% of the 5335A counters work

out of the

box. The most common trouble has been the A3/A12 boards with bad

Schmitt

amplifer ICs and signal relays. You need to be able to work on densly
populated circuit boards to repair these. Another common problem

has been

the power supply switching relays overheating on the older models.

Later

designs cured this by changing from a 120 VAC fan to a 24 VDC fan

along

with diode protection from the inductive load switching. I can go

on for

many pages about other issues I have found in the 5335A models and
repaired, but will spare you and the group. I you want more

information,

please contact me offline.

The 5334A models have their share of issues, but because of

simplicity and

somewhat newer design, the only real issues have been the signal

relays on

the main board becoming stuck in one position or the other. This

is easy

to fix with a soldering/desoldering station and parts that are

currently

available from Mouser.

Now the real issue is that you need some basic test equipment in

order to

align these counters once you get them working. When there are no
defective parts, they work pretty well, but severe alignment

problems will

stop them, and you need to be able to align your counter to ensure

that

your measurements are accurate. For that, you will need a two channel
oscilloscope, signal generators, such as a 3325A/B for the low
frequencies, 8657A or similar for the high frequencies, pulse

generator

(8082A), and a good frequency reference, such as Rhubidium

Oscillator or

GPSDO (Z3801A or Thunderbolt). You may need some additional gear for
Channel C such as a 8657B (1300 Mhz), a power meter/sensor, and a

50 ohm

splitter.

These are great counters and do a remarkable job, especially

considering

their age. I truly enjoy working on them and refurbishing for

others to

enjoy. Choose a reliable seller - many of the "Top Sellers" will

send you

garbage and will not pack the equipment properly, but that is a whole
separate topic. Best of luck with your decision.

Joe, KN5U

The 5334 and 5335 also have reciprocal counting, so keep an eye out for
all of
them. Last 5334B I got I paid $40 and it was mint. It didn't have the good
timebase oscillator but I use a rubidium distributed around so didn't need
it.

These prices are insane for what you get.

Paul,

if you want to measure low frequencies with high resolution, you will
definitely want a counter with reciprocal counting. Otherwise you're
waiting
for ages, especially with audio signals.

The 5315A (w/o HPIB) and 5316A/B (w/HPIB) are the best bang for the buck,
IMO.
They are powerful tools, small, come without a noisy fan and can be had
for
stunning little money if you are a little patient.

Compact size and latest gee whiz item is not so important as budget,

So many models I thought I'd start here

Thank-you

Hi,

Is there a fairly simple keyboard command that will set up the 8920B

to 'hold' the last instrument settings for recall when the unit is
next powered up?

I don't know about this instrument, but on my 8720D VNA, if a
calibration state is saved with the name "UPRESET" then it will power
up with that setup. It's a long shot, but you could try naming the
setup you want UPRESET

If one gets one of these and it doesn't work, how repairable is it?
