Re: Wanted: HP 10509A Loop Antenna, part of HP 117A VLF Comparator
Hi Dan:
The antenna is not tuned and I expect would work over a wide band.
PS there are two versions of the antenna, one uses a couple of 13CW4 Nuvistors and the other uses FETs.

Yes I am aware that you don't need the keyboard to control things with
out but it seems easier to do.
And I like to find all the bits is possible.
I will try out the keyboard that I have. There are so few details on
the.

I have the same rig, more or less - it didn't have the keypad. I think
you can do without it and control everything from the screen menus, while the
keypad allows for shortcuts to the basic functions, or to operate it with
various programs - or maybe not. Anyway, as I recall, I could run it just fine.
I think the keypads for the various uses are all the same inside, with the
difference being the button labels. I later acquired a keypad for a different
type unit, but have not tried it to see what happens. I think you could
probably use the one you have, and just figure out what the button functions
should be.
Unless you're going to need its full 40-50 GHz capability, it's best to just
adapt the inputs to SMA-compatible types. I bought some short (12") cable
type adapters, which were much cheaper than the ideal, simple straight-through
barrel types. I made a little box that mounts onto the input connectors, with
the cables inside, and SMAs on the right side, to make it less obtrusive in the
front.

I’ve acquired a nice HP 3330B Automatic Synthesizer after some testing it started up with a wrong value on the amplitude display. Some testing revealed some other quirks when I want to alter the frequency it displays the input on the amplitude display and changing the frequency and amplitude with the up down keys also gives strange results on the display, also some other keys don’t work as they should. After some searching, I’m convinced something is wrong in one of the processor boards. I’ve looked with the logic analyzer and can see the logic is starting up as it should it follows the state diagrams in the same order as in the service manual.
I’ve tested measured a lot and can’t find the fault at the moment, so I’m looking for a working set of logic board (A7 ALU board and A8 control board) and if some body have them an image of the control roms (4 x 256bit ROMS) so I can check these against the images I’ve made of my ROM’s (82S126 compatible). If someone has a set of boards ?(A8, HP 03330-66575 and A7, HP 03330-66507) and/or the rom images, that would be very nice and should make me possible to fix the 3330B so I can use it in conjunction with the HP3570A to restore a HP 3041A VNA. ? -Rik ?

Re: My $25 "In Poor Shape" 3468A has arrived
Hi George,
While I write this I am letting the DVM run for about 30 minutes prior to doing the Zero cal procedures, as recommended in the manual. Since you did not mention this not sure it is only needed if further range calibrations would be done, but I assume it won't hurt. I am also running a bit the A/C as today's temp is already at 28 C, so to bring it down a bit more towards my usual environmental room temp of 26-27C as I would guess would make sense to perform the cal around these temps. In the summer (in a few months) the house can get up to 30C with out the A/C running.
Since you pointed out earlier in this thread that one cannot calibrate the DVM to both 2W and 4W ohms due to lack of storage space for the constants, I figured I Zero calibrate the 3468 for 4W, and the 3478 for 2W, so I have one of each calibrated measurement modes. For a general check I have a couple of low ohm precision Dale resistors (btw 0.05-1%) resistors for a general check of the lower ranges, and also build a small resistance standard box from 10-ohm to 10M by using a Caddock 0.05% resistor network a 1-2 extra resistors which I ordered from Mouse some time ago. But so far never had a chance to characterize them on a well calibrated meter, so they are just good as a general reference and possibly to detect calibration drift on the meter over time. But then obviously the resistors will of course also drift some over time. Anyway, will use your red devil resistors to check the higher 30K and 300K ranges.
OK 30 minutes warmup time are up, temp now at 26.5C.
Pushed in both your jumpers and wrapped around them tightly a shorting wire at about the same position on both jumpers to hopefully force the same potential. Letting them temperature stabilize a few minutes, although I only touched them by the tape you put on them.
On 4W the 3468 is still measuring -000.093-94 so pretty close to what it was before. After the cal sequence display reported "Zero Done" and reading is now all zeros, no more negative sign, although I am still in call mode. Will do the same for all the other resistance ranges as well.
Went out of cal mode, and now reading in 4W with both jumpers in, and bridged together still reads 000.000. If I go to 2W I get a reading of 000.059 ohm. I guess this small error is to be expected as the calibration was performed on 4W.
Now your Red Devil resistors. At first I pushed their leads directly into the input jacks of the DVM, but then realized I was heating them up while holding them in my fingers. So then secured them onto a dual banana plug by tightening down the holding screws and plugging the whole thing into the input jacks without having to touch the resistors.
In 2W mode the 20K resistor measured 19.9661K, same reading in 4W mode (your measurement being 19.97140K).
The 98.975K resistor measured 98.980K, and on 4W 98.978K (your reading was 99.00352K).
Looks like I could use a bit of fine calibration, or the temperature difference between your readings (22.0C) might be playing a part.
In any case would it be possible to use your two resistors to at least get the 30K and 300K ranges more closely calibrated?
Thanks.

Re: E4401B No 50MHZ Cal signal
John,
Thanks for the info and with the part number I was able to get the service guide PDF. I also found a section at the KO4BB website with lots of E4401B manuals, which I am sure most of you already know about, but just in case here is the direct link:
The trick was definitively to search for E4401B instead of E4411B and/or the specific manual part number.

Re: hp3586a selective voltmeter jammed
Yes. It was frozen just the same. The unit was in storage for some time and when I tried to use it the display was frozen. On the microprocessor board there is a battery for RAM back-up. When the battery failed, I guess the processor did not know what values to use at boot-up. I also have a Yamaha HS-8 digital organ which also had a frozen display at power-on. It was a bad battery backed-up RAM chip which failed. I replaced the RAM chip and the organ was OK. You might wish to check any battery back-up circuit and battery backed-up RAM on the processor board. On 2019-Apr-15 5:33 PM, cc@... wrote: Hi Merchison, thank?you for sharing your experience. Unfortunately the HP3586A does not have a front-panel battery but a NiCd one on the power supply board for which I had to clean in the vinegar the same power supply board and the micro controller board to remove the residues of the leakage. My understanding is that the presence of that battery is not strictly necessary for the normal operation of the hp3586 and indeed, after cleaning, I also removed it temporarily. Just a curiosity: was it perfectly the same frozen display?
