Re: Hp 8590a eeprom problem.
Yes I cleaned the contact points with alcohol and q tip, for the female receptacle part I used a acid brush and alcohol.?? Well guess what, it worked good, put the cover back on and my friendly fail code 1310 appears again. How aggravating. It indicates eeprom u21. I got the part number off the IC PMI 8639 1826-1048. I'm not sure how to read the chip I see a lot of chip with 1826-1048 but not the first number 8639. Can someone enlighten me on this.? Thanks?

Matt - AFIK, the source modules are not connected to the 8430 in the same way they are connected to the 8350 (and also, I believe to the 8673).
I'm just starting to play with the source modules (HP series) and will let you know. I believe I will need to use the 8510 multiplier technique.
Cheers!

Take a look at Controlling Multiple Sources in the 8510C operating manual. Forward a few pages there's a section entitled "SOURCE 1 Formula Use". This allows you to apply offsets and multiplications to a source.
If you have the official HP/Agilent mm source modules, these should have a bus that does this for you; i.e., you don't need to mess with these menus.
If you don't have the official modules, then this would indeed be the approach.

Matt - Sure - I just never thought about it that way - I was thinking that the 8340 would be where the configuration was done.
No problem

The 8510C doesn't apply frequency offsets or multiply your RF source signal. It simply tells the RF source to generate a frequency that is some combination of offset and multiple or submultiple of the displayed frequency for a given sweep point. Probably obvious, but worth clarifying. This is all explained in the manual.

If i have to go lower than 26 GHz i connect direct the 8340B to the 8515 without the multiplier or multiplier x1. thats all. That's a cool capability I wasn't aware of. Thanks for pointing that out Gianni. It would be nice if the 8510 could control a switch driver controlling a pair of switches too. That way, you could get the full 10 MHz to 52 GHz in one sweep. That would be useful for things like time domain low pass mode. I didn't see anything about that in the manual though.

Hi Gianni,
Can you elaborate on this 8510C setup a bit more? The 8340 through the
x4 Marki goes to an 8517? Does the 8510C software handle this fine? Do
you just restrict the 8510 frequency range to the quadrupler input range
and then just adjust the display readings in your head? Or, does the
setup work a little differently?
Thanks

Hi all,
Does anyone have a copy of the Agilent/KS PNA legacy firmware files? This page was up until very recently, and of course now I am working on an old unit that needs fw:
If anyone has these saved somewhere please let me know. I can host them on my website (neonkev.com) for folks in need in the future as well.
Thank you!

Re: PNA (E835XA) Hard drive issue
Hi Julien,
Would you be able to share an image of the 266MHz drive with windows 2000 if possible? I am trying to resuscitate an unbootable 266 MHz unit which I know has an OS problem.
Thank you, Kevin

Re: Suffering from RIFA anxiety!
Filters on power cord entries are as much to protect the instrument from RFI as to protect the power line from RFI.

Re: Suffering from RIFA anxiety!
Hi Dave, I was, and I wasn't. The Schaffner filters are reported to contain the yellow epoxy covered RIFA brand capacitors in their internal filters... They would seemingly have to be some sort of safety cap because they come before the fuses. I have seen RIFA caps that were used in other ways that were bad, though I have not seen one blow up. It might be time to blow a few just for the experience. -Chuck Harris On Sun, 11 Sep 2022 19:02:41 -0400 "Dave McGuire" <mcguire@...> wrote: Jeeze Chuck, my mistake, I thought you were talking about Rifas, not Schaffners.

All I can say is in 4 decades of designing, using, and repairing electronic equipment, I haven't seen a Schaffner filter blow up. Tomorrow may be the day that I may see a dozen...
The goodness of the whole idea of putting several safety caps, which are designed to blow without catching the instrument on fire, in a can full of tar eludes me.

Mostly the failure rate of RIFA paper dielectric safety capacitors, with clear (yellow) epoxy potting, is related to how large the difference is between their design failure voltage, and the voltage applied.
In other words, for older capacitors: If you use a 250VAC RIFA cap on 240VAC mains, failure is all but assured.
If you use a 250VAC RIFA cap on 120V mains, you will likely never see a failure. That's nowhere near true in the field, unfortunately. I've replaced two 250VAC RIFA capacitors run on 120V in the past week alone. These blow up *all the time*.
Storage in a humid environment dramatically accelerates the failure of RIFAs.
Or so says my 40 years of experience as an engineer, with never seeing a single RIFA capacitor failure on 120VAC. You've been lucky.
