Good stuff.

Would anyone care to share the option screens?

I'm interested to see how these are optioned out.

Cheers,

They refuse to provide their software to customers directly due to licensing issues.

It's a really great piece of gear, but there are many things that can go wrong, and those 30 or so relays under the unit are a concern. Should one of them become a little flaky, it would be a nightmare to track it down.
The UPL sports a 44-pin IDE interface for the HDD. R&S used mostly Fujitsu brand HDD at the time for many of their instruments but they did develop a bit of a spotty reputation. I backed mine up to an industrial SLC SSD which just fits into the very limited space and appears to work well.

I ordered this for the HDD backup:

Inateck USB 3 0 Hard Drive Adapter Converter DVD 2 5 3 5 5 25 034 SATA IDE SDD HDD | eBay

That should allow me to connect this drive to another to clone the contents.

There is an INSTALL directory on the system drive. It appears to have a copy of the install disk there. 16 files total, LZH archives and some bat and doc files. Perhaps that, along with the setups and cal files is all that's needed to start with a new disk? I've sneaker-netted those files to a Windows PC for safe keeping.

It's a tighter squeeze than what may appear since the IDE header is oriented in such a way that depending on what replacement drive you use (PATA vs SATA+adapter), you may find fitting it in a challenge. Also, please note the red circle around the Pin 44 marking. There is no socket to orient the cable so this would be important.

Good luck.

I don't see any other option than to unplug the drive and remove the screws holding it in place and do the cloning outboard. Am I missing an easier way?

Taking the HDD out to clone is not a big deal. Just be careful of the metal edges inside since the space is tight and some edges are pretty sharp.

Cuts are the least of my worries when working inside a $40,000 instrument. :-)
Believe me, some amplifiers I've worked on have left me bleeding like a stuck pig! This is not too bad, actually.

Does anyone have any idea why a cloned drive of the same model as the UPL drive produces a DISC BOOT FAILURE when swapped in for the original drive?

This happened two different times. The first was with building a new system disk. I did this by connecting my bare drive to an Inotek adapter on a Lenovo laptop and using disc mananger in Windows 7 to delete the 20GB partition and re create a 2GB partition that DOS could format. I formated it with a bootable DOS disc "format C: /S". Then I copied the rest of the UPL files to it.
That disc would not boot.

Second attempt was by doing an exact clone with Norton Ghost 2003. I copied the UPL drive to an image file on a 4GB USB thumb drive. Then I replaced the UPL drive with the blank Fujitsu 2020 drive and wrote the image back to this drive, overwriting the original partition made with DOS 6.22 earlier.
This disc would not boot either.

I've never seen a system that could discern a cloned drive as not valid before. Is there no way to make a PERFECT clone of the drive such that the UPL will not think it's a fake and issue a disc boot failure?

It's been a while since I messed with drives like that but have you looked at the physical jumpers on the hard drive? Are they in the same master or slave position as the original?

Part of the mystery is solved:

The disc was invalid media to the UPL and that turned out to be due to the software used to partition the drive.

I re partitioned the drive from a DOS boot disc and was able to get the UPL to boot to a C: prompt.

However, once I restored the Norton Ghost image of the original drive to this new Fujitsu 2020AT (same model as original), the UPL seemed to corrupt all the data, or the data appeared as gibberish.

See attached screen shots, showing the various stages of progress.

Note that Norton Ghost found bad blocks on the original UPL drive. When I showed these on computer forum full of DOS experts, I was told that this looks like software copy protection. "a number of tricks , some involving hiding data in clusters marked as bad, etc." and "that locked itself to the installation HD using (I presume) the HD's serial number."

After cloning the drive, sector by sector, I have a copy that is unreadable in the UPL, as shown by the gibberish characters when the system starts and tries to read the autoexec.bat and config.sys files.

However, if I move this drive to a Windows 7 laptop, these files become readable again.

For some reason, this particular Fujitsu drive seems incompatible with the UPL drive controller. Is there some sort of encryption between the controller and drive that is locked to a particular drive serial number?
