I have bought a 70420A phase noise test set - the heart of E5500 phase noise measurement system and used it with HP3561A and, later, with HP89441A samplers.?
It needs a PC software package to be anywhere close to being useful.
Agilent E5500 software is available on Keysight website but requires a key tied to the serial number of the test set.
I have been advised that Keysight is kind enough to resend it to new owners of old E5500 equipment but few emails requesting the key went unanswered.
Do you have to make up a compassionate story of why you don't have the key or has Keysight simply finally stopped supporting these?
In the end I have simply programmed somebody else's S/N into my kit and am using their licence key but I am wondering whether I did not try hard enough with Keysight tech support?

Reading the manual of the counter , I verified the command to get te ID is "ID" or "SI".
The instruments doesn't support the SCPI standard command syntax .
On Agilent I/O there is the possibility to disable ,during the serching instruments , the *IDN? command.
I not remember if using NI Max there is this facilities
Best regards

Hi Mark , I suppose teh counter interface was setted on listen mode at first.
You can check if the NI Max is sending *IDN? command during the search for instruments.
May be the counter doesn't support this command.

Agilent 16700B/16702B Manuals
I am looking for the User manual and also the service guide for the 16700B/16701B/16702B series mainframe. I'm pretty sure I have seen it, but cannot find it now... And I don't seem to be able to find them on the Keysight site...
Any place they are on the Web?

Re: I'm officially lost now with this 8753ES
I ordered the CLIPs from the ebay seller who likely got them from Manuals Plus which is now gone.
Nothing is obviously wrong with the VCO drive to the YTO.? I say "obviously" because the waveform has the same shape as it shows in the manual, but yet the voltages are off, most especially at the low frequency end where the manual says the drive should be 3.5 volts it is actually 4.0.? But is this a normal difference or has the PLL card drifted out of spec?
If I get a hold of another A11 card I will know that answer.
So here's the thing:? is it possible something I did in the hybrid module could have caused this?? I would not have thought so as it is operating at high RF frequencies only and not directly controlling the YTO frequency, especially when the PLL loop is opened.
I am thinking I will try and draw out a diagram of the PCB on the source module.

As far as I know, the A3 source board schematic has never been published in a CLIP. I once saw it, and to my eye it didn't look nice enough for official publication. It was probably just good enough to extract the netlist and lay out the board. I suspect they never intended to publish it, so they didn't spend the money on making it look nice.

Hi all. So, hooked up my acquired 5385A to my HP-IB (GPIB) network and it crashed! The unit has "Error 52" on the display.
Tried it all by itself and same issue. (This is with NI MAX... search for instruments) Have NEVER seen this before. Even NI MAX
has problems when the counter is connected. Google search reveals that others have problems with LabView but not helpful.
I have NOT tried using BASIC (hp 85 for example) with the unit.
Any advice on this please?
Thank you!

PS - this error indicates "First character of command is illegal"

Re: HP/Keysight/Agilent 34401A DMM power transformer
Siggi
Again, thank you. Amazing (to me) the Keysight part is only 10 dollars more than the Chinese eBay replacements. So no contest there....And the video you linked shows the transformer hanging on the side rail of the chassis, so that should be easy to rig.
I will cross my fingers and buy the Keysight part.

Thanks for the info from the service manual. I see that there are a few on eBay (all from China) listed for the 34401A, but the part number is 9100-5608...
From the photo it does look to be a compatible part, at least in terms of the winding terminations. At $70.00 (US) each, I guess it might be worth it if it brings my meter to life! I just hate buying from Chinese vendors (not because of politics, simply because delivery is slow and unpredictable)
Then buy it from Keysight []. The registration process is a bit of a PITA, but the one time I bought a part from them it was Fedexed overnight at zero charge. ? So I was hoping maybe someone from the group has one for sale (or a junk unit I could cannibalize).
Has anyone replaced one of these? I wonder how the transformer is physically attached to the chassis?
There's a lot of info on the internet, see e.g. here [], or you might want to look at the parts diagram in the service manual.?

Suggestion:
Use any xfrmr that is electrically compatible, and mount it outside the DMM inside it's own little metal box - sorta like a "wall-wart" PS setup.

Re: Maintaining good Firmware EPROM, PROM, EEPROM etc.
Hello,
I can also recommend Batronix programmers. I have used BX48 Batego II almost two years without any problems. This model is quite pricy but worth of every euro. Batronix support is excellent, if you have older chips not mentioned in their chip support list, they will tell you which settings you should use .
BTW: Does anyone have extra HP 8751A CPU card? I don't have 3-pin row euro card extension cards or cables. Repair without pulling the CPU out from the frame is almost impossible. I have checked EPROMS and EEROMS and they are ok. I swapped CPU card from working HP 8751A and it works perfectly. With faulty CPU card it looks like working, but the source frequency is not sweeping. Internal tests don't give any errors, but step oscillator and FN oscillator tests returns "not assigned".

Re: E8357A upgrade questions
I guess I should have also mentioned that I can provide the CPU and hard drive at no charge.? I would rather see instruments being properly used rather than being dumped in a landfill.
You will need to purchase a #2335 lithium button battery ($5) since the existing one is probably dead. This is just for the real time clock.?

Re: E8357A upgrade questions
I have bad news, bad news, bad news, bad news, bad news, and good news.
1. The 266MHz CPU is not worth using...nothing is supported with that.? And Win 2000 is no longer supported either.? And it is dog slow.
2. The max memory on that CPU is 128MB.
3. The 10GB drive is not worth using and is unreliable after ll this time, but you could clone it if you wish.
4.? It is unlikely that you could get the PNA to work at 9 GHz.? My memory is a bit hazy but I think the 6 and 9 GHz units are identical (or maybe it was the 3 and 6GHz?? or maybe all 3???), but without the keyword to unlock it, you are out of luck.
5.? While I could generate the proper keyword for it, I won't. Sorry.
The good news:? I have a few used 500MHz CPU boards available (with 512MB of RAM) along with a 40GB XP hard drive.? A 1100 MHz CPU would be even better but I do not have any and those are hard to come by.
You should send me your contact info/address.
