Don, I appreciate your message encouraging me to tackle this 3455A.? I have made a few inches of progress with it.? The 10V reference is spot on.? The input voltage from the panel reaches the A10 board.? The manual indicates the problem may be with one or the other of two ICs, one of which I replaced with no difference.? The other is soldered in and I would like to know if I can test it in situ before trying to find a replacement and installing it.
The unit responds to the panel and acts as though it's working but the display shows zeros.? On Ohms it even puts out some current via the input jacks.? So it works but no cigar.
Of course I don't have a spare unit to swap boards.? So I am baffled at this point.? All suggestions welcome although paging back and forth in the manual to figure out what is where is a bit troublesome.

Re: First Gen HP 54810A with dead HD, Got ISO 3.5, Any way to write it to a drive?
Maybe it's worth to try a more recent version of Norton Ghost to recover the .GHO image on your Windows 10 machine?
Windows 10 still has a compatibility mode for running old software, did you try it?
Another option would be to obtain a Windows 95 virtual machine (here:? ) and to run the software on it.

Some customers have been successful performing system recoveries with external CDROM drives from companies such as MicroSolutions. These drives connect to the scope¡¯s parallel port. Since this method of recovery is unsupported by Agilent, customers are responsible for all configuration of the external drive. 8 For the recovery to be possible, you will need to mount the external drive and boot the scope from a floppy disk (the drive¡¯s manufacturer may be able to provide this disk for you). At the DOS prompt, you must be able to navigate to the drive and see the drive¡¯s contents with the dir command. If you can successfully get to this point, you should be able to perform a recovery with a special A.03.50 recovery CD. You may download the CD image at the location given below or contact Agilent technical support for a copy of this CD. The following recovery software is available for download. This is an .ISO CD-ROM image file. You will need to use CD burning software such as Nero or Easy CD Creator to create the CD from this file. Do not simply copy the file onto the CD as this will not work. A.03.50 Recovery CD: ftp://ftp.agilent.com/pub/callpub1/ddt/scope/548xx/Upg_Rec/3_5/3_5_rec.iso?

Do you happen to know what options were on this 8640B? I'd like to expand the options on my OPT323 version to those on the avionics versions... even if custom.
My OPT323 still needs work on to get the counter going, plus verify other functionality when the corroded and suspect parts are replaced.?
I have cracked gears and need to repair or replace those too.? Thinking will repair for now since I'm on the tight budget plan.?
Might be able to use some of the boards if they'll swap or can be modded to fit to enable more functionality.?
Wouldn't hurt to have another 0860-60029 (looks like I have a 08641-60029) and 0860-60177... assuming they're compatible boards for the price.? Then again... might just be cheaper to repair the ones I have unless there's a component that's unobtanium.??
Any thoughts from those more experienced with this make and model?
Thanks

Re: HP 419A DC Null Voltmeter - INSANE behaviour
When you don't ground the center of a balanced supply (two
batteries in series + and -) you don't supply a ground, and the
overall voltage doesn't balance unless the current draw is exactly
balanced, so the circuit sees, say, rather than +13 and -13; maybe
+15 and -11.? There's also the problem that the impedance of each
supply (supposed to be low) depends on the rest of the circuitry
(like the +13 being influenced by the -13 and vice versa.).? No
guarantees what happened (electrically), but oscillations are not
at all surprising.

Phase Locking an 8350 Plugin
Hi Group! Has anyone tried doing this? I am going to try it but the manual for the 83590A (2-20 GHZ) is a bit confusing.  I found/bought the 8709A (unknown condition - might be a new topic!) and a 934A mixer. The Sig Gen (8640A, Opt 002) runs up to 1024 MHz. But the 8709A compares to 20 MHz so the Sig Gen I think needs to be much higher than 1024 MHz! What am I missing here? The next part of the manual:  A bit hard to read but it says for Fo less than 2.0 GHz??? That's outside the range of this plugin, so makes no sense. At any rate, gonna play with this. My RF gen only goes to 1024 MHz so can't go to say 10GHz - 20MHz. Hmm. Thoughts appreciated. Mark

Harvey, my main problem is identifying the various parts.? The manual isn't the easiest for me.? Perhaps you can walk me around to the various places where I can make measurements.? I certainly have no shortage of sources of dc or ac of any reasonable frequency and amplitude.
I did measure the 10V reference with my 3456A at 10.00007 I think.? (not sure how many zeros)? So what we have here are all the pieces of a good meter if I can make it play.

Re: HP 3325A/B Option 002 HV output kit - who wants one?
Ok, I've got everyone who has posted or messaged me on the list now.
I'll put the current list up this weekend so you can all double check and correct me if I made any mistakes.
?
A little bad news though.... Due to the Corona virus, Japan Post has basically shut down all deliveries to 153 countries as of yesterday....
It ultimately won't stop me from completing this, but it will delay things for a while, and I have no idea how long.
?
I'll keep the updates coming, and if I can get the PCB's delivered (The major carriers like Fedex, DHL, UPS, etc are currently still delivering into Japan) then pictures and a few performance tests will be forthcoming too.
Anyway, orders will remain open until the last minute, so keep the list growing! I got 53 PCB's to order on the list so far (and a big portion of those are full kits, so I'll have a good amount of parts to sort through too!)

Re: Maximum depth of HP rack mountable gear?
A good point, especially for wooden floors.
No worries on my part though as I have a steel framed house with very strong floors. Being in Japan, the building is rated for the big earthquakes we get here so a rack is easy work for the structure. :)

Re: Fixing a sick 4332A LCR meter
Hi Joel,
I will pick up the Artek version. Probably won't do any more work on it till the weekend, but to follow along with your thoughts:
- none of the ranges work. in R, the needle pegs HARD off scale high unless the leads are shorted. In C, it registers very low, and there's a lot of random needle movement, same for L.
- In C, there's a ~12 KHz ~20 mVpp sine present on some ranges, not present on others.

Re: Maximum depth of HP rack mountable gear?
You guys already know this, but just in case: an important consideration in rack mounting your gear is the weight that the floor can support.? With some of the taller racks filled with equipment, you will have hundreds of kgs. of weight.? As an extreme (and fabricated) example, a common 7 foot (44U) rack could physically accommodate eleven HP8664A signal generators.? At 35kg each, these generators would weigh a total of 385 kg. (850 lbs.) -- and this doesn't including the weight of the rack itself, and any mounting accessories.? Be safe, everyone!
