Re: 3" disks for 8566A/B, 8568A/B on HP 9000 Series 200 Computers - Any interest in images?
Your PC must support 256 and 512 byte sectors and the number of sectors per track used by LIF formats to successfully read/write disks. “Super IO” chips that implement PS2 keyboard/mouse, IDE, a parallel and one or two serial ports plus a floppy
interfaces should have no problem(usually 80486 and earlier Pentium). Somewhat newer systems that had the parallel port and floppy, serial/parallel/keyboard via the LPC interface also usually have no trouble(late 486 or earlier Pentium to later pentium maybe
P2/P3 typically). Anything Pentium 4, core, core2 and newer you’re probably going to be out of luck. There might be some exceptions, like certain servers that had an LPC interface for a parallel port (for license dongles) that also happen to retain a floppy
interface.
In principle, a USB device could support non DOS formats but most likely do not. There are some specialized hardware out there .. flux something or another intended to read raw media that could do the job via USB.
Something like an old D630, or more generally D600 to D630 and D800 to D830 that can have a floppy, CD-R, DVD or battery in a hot swap bay that’ll do it as well.

Tried the Github version v2.0.0 as suggested. It could not read any of the disks
Tried Keysights LIFUtils. It could not even format a 3" floppy to LIF using XP or W10.
(Both O/S could read and format a floppy in Microsoft formats so the h/w is OK.)
?
After at couple of hours I gave up.
?
I think I can still have an old original HP 3 1/2 " floppy disk unit somewhere
with a GPIB interface. I also have a HP Z400 with a NI GPIB card used for KE5FX VNA utilities.
?
Anyone that knows if there is software that can be used for reading out the contents
using GPIB?
?
Now it is man against the machines...

Keysight 23522a Binary Arb Files
Hello Community,
I got a 33522a Arb Signal Generator. I'm still looking for a file format description of the binary arb file format ( *.barb ). I found some information about this format and I still can create this files with the basic Parameters - Number of Channel - Numbers of Data Points - Vmax - Vmin - Checksum - Datapoints
I found some information about the ASCII Version of the file format ( *.arb ) and there are some more parameter i can set. The problem ist for using the whole 16M space i do need the binary file structure.
Finally there are several 32bit or 64bit int / float values which are unknown for me. IT seems to me this unknown values could set a lot of interesting Parameters. Is anyone in this group who has a full description of the *.barb file format for the 33522a series?
Alternative could be someone who hast the keysight sw benchvue with Wave Form Option for creating such binary arb Files. He could create a Set of Files with different settings. This could analyzed by my sw.
Thanks and best regards TomS

Hi, ? I have the installer "Install-4192A-V1-light.exe," which means that the NI libraries, for example, are not included. If you would like this program, I can send you a OneDrive link. ? Yves
Could you please upload a copy to this directory which I created for the purpose. Place any information you found - a copy of the webpage would be good.

Hi,
Does anyone know what happened to the website for the HP 4192a sweep utility written by Michael Kelzenberg?? I didn't have it bookmarked so don't recall the URL, I think it was on a university website.? It's completely disappeared from search results online.? I luckily have a copy of the installer I downloaded in November, but someone else asked me where I got it and I can't find it anymore.? It would also be nice to have a copy of the text of the site for reference. ? Thanks!

Re: HP 8673D synthesized generator - need replace RF out connector - partial front panel removal suggestions
Thank you, Yves, about working on lower section.
I now wish I had made photographs of top-of-bottom, and bottom-of-top areas. There is a panel separating the two sections, with ~8cm x ~15cm opening near front for wires to pass top-to-bottom. I wish HP had used flexible cable for RF between the sections (two cables), this would make separating the sides easier.
Fortunately, when I was re-assembling, the two UT141 section connectors arrived very close to original position (I had not applied stress during dis-assembly), so there was no worry about reversing the two connectors (which go to switches next to the output step attenuator.)
After repair of 8673D, I tested output using my Tektronix 2755AP analyzer (I have had since ~2015, also old machine almost ready for scrap pile) to look at very narrow span (down to 100 Hz/div) for spectral purity. Tektronix 2755AP analyzer is providing error messages (about IF2 frequency control, it is strange "frequency locked loop" under control of firmware, and it is not PLL!) so it is next big machine for repair here. Adjustments are made with many many many small potentiometers, guided by primitive firmware. New adventure!
Some flat head screws inside (which are in many places along both sides of HP 8673D) are M4 x 4mm. I believe HP used many metric fasteners. I ordered some for spares, because of course it is easy to permanently lose specialty fasteners!
On the output connector (HP part number 08673-60040), it is used in other units, including HP 83595A and 83594A plug-ins for HP 8350A/B, it is used in HP 5348A counter/power meter (which is strange animal, like power meter with no option to set correction factors, and frequency counter, in same box, but with zero integration except shared LCD digits (????), and also connector is used in HP 5343A frequency counter, HP 8563E Opt 026 spectrum analyzer (and other/newer models). From the part number, I believe HP 8673 series was first requirement for front panel 3.5mm connector.
I searched for long time to find spare 08673-60040 connector, it is not so pretty, but it is working OK. Now there is one for sale on auction site (by supplier in israel), but cost is very high. Perhaps create search trigger for part number, after some time I think another will appear.
There is other kind of 3.5mm panel connector from HP, 08513-20017. It is I think used in modular plug-in microwave test equipment (HP 7000 mainframe), it is much lower cost connector on used market. I do not know if bulkhead hole diameter is compatible, but it is possibility. The original connector type is more rugged against damage (but as you found and I found, damage is still common.)
So, thank you for dialog about HP 8673D service adventure, and it is nice machine, almost weighs as much as adult person!

Re: HP 3403C True RMS Voltmeter display fault
Hey everyone,
?
Just to inform everyone that the 3403C is back together and running happily.
I let it warm up for 3 hours, set up the power supply and used my Adret 104A to setup the DC part. I had to trim the capacitor for the DPM to get back into alignment and that's about it, it's well within spec on the DC aspect and at least up to 100V.
For the AC I do not have a trustable source so I do not know for now, we'll see later.
Thanks everyone!
Arnaud.

I just bought a Manual yesterday and the download link arrived around
one hour later. But i did the automatic paypal checkout, so no manual
communication was involved.

An unfortunate choice of words. The owner of Artek (and member of this list) sadly passed away fairly recently but yes, his wife is still running things and I've had several manuals from them in the past few months but understandably timescales can be a bit variable. Sometimes the download link comes by return, sometimes it takes a day or two.

Check that the responses aren't being filtered as spam, especially if you use GMail since it seems to change it's internal filtering criteria frequently and without notice. This happened a year or so back to me with Artek.

Re: HP 8673D synthesized generator - need replace RF out connector - partial front panel removal suggestions
Hi,
Glad to hear you were able to successfully replace the connector. I kept
your notes for disassembly; I'll probably have to replace my connector as
well. Where did you find the replacement?
Regarding your low-frequency output problem (10MHz-2GHz), I've had the same
problem twice: no more loss at 10MHz and less and less loss as I approach
higher frequencies. It's probably the Watkins Johnson 6203-044 amplifier (HP
0955-0215). The internal screws make the ground contact. I tightened the
screws, and everything returned to normal. A few months later, the problem
returned. I then soldered the ground contacts instead of relying solely on
the screws. Since then, the problem has never returned...it's been two years
now.
This amplifier is located in the lower part; simply open the bottom panel,
and you have access to the amplifier.
Here's a picture showing the specifications, the amplifier itself, and the
results after the repair.
Attached are some tests I performed once I had completed all the repairs to
ensure optimal operation.
The 8673D, the excellence of this generator is matched only by its weight :)

Mini tower or thin client would be great. Anybody have a PC they don’t need? Thanks in advance.
