Re: Copy contents of floppy in 8753 VNA to a PC
Is the floppy drive unit in the GPIB interface box, a standard 1.44MB 3.5 inch type? If so, perhaps you can replace it with a floppy drive emulator, that can also be accessed via USB.
(If unfamiliar with this type of device, google "floppy drive emulator")

Probably need a BASIC program to read the data and push it out the parallel port using the "OUTPUT @Nsomething" command. The BASIC commands are pretty powerful. Don't know if anyone has seriously tried this as it is probably not very obvious.
This has been a problem for a long time and most people end up circling back to using some GPIB adapter and custom GPIB software.

looking for Kelvin clips for HP 16048C LCR test fixture
Hello all, ? I have an HP 16048C LCR test fixture that, like many, is missing the Kelvin clips. ? Does anyone have a source for a suitable replacement? Looks like they are obsolete per Keysight. ? These alligator clips are a little unique in that they plug into rectangular connectors coming off the fixture. The connector housings have a small PCB inside. Each side of the PCB carries one of the two signals for the Kelvin connection. ? Per the service manual the parts I am looking for are 16036-7511. ? I¡¯m tempted to hack something together but given the rarity of the fixture I really don¡¯t want to modify the connectors. ? Thanks in advance for any replies. Jeff ?

Re: Hp 8590a eeprom problem.
Ah, I was about to go look that up.
It's not unheard of for 2816 and 2864 NVRAMs to fail.

Re: Looking for Agilent PNA old FW repo?
There may have been "snapshots" taken at several times. Be sure to check any snapshots covering the time when you think the SW was listed. Also, if it was on HP FTP site you might look to see if wayback covered that anytime.
Cheers!

The wayback machine saved the page (same one I linked), but the actual firmware files are not saved on the wayback machine from what I can tell.

Re: Suffering from RIFA anxiety!
I reached out to Schaffner directly and they said the following:
Our capacitor ratings X1, X2, Y1 or Y2, depending on the filter, and
should fail open. We use ceramic and Metalized Polypropylene Film caps
in our filters.
So, good news, new Schaffner filters should be free from metallized
paper failures.

Those are part numbers and date codes. The numbers ave nothing to do with the programming.

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!

Something I've missed also. Where in the menus do you find the
appropriate settings ?? This would be convenient when using the mm
source modules. I believe it's under System -> More -> EDIT MULT. SRC.
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.

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

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.
