Along similar lines, I've used OpenSCAD a little, but recently
came across BRLCAD, which was developed at the Ballistic
Research Lab in Aberdeen MD. It uses TCL for scripting.
So it boils down to a programming language with geometric
primitives. I've thoroughly enjoyed using it.

I suspect the 'scope is too old for lithium.? I will peruse the manual and see if there is indeed a battery in it.

Thanks for the heads up.

Hi Leo,

I don't know the instrument at all but from a philosophical point of view, I'm not a great believer in simultaneous and unrelated faults so if changing the battery made a significant difference might there be some set-up function that needs changing or simply re-entering as the value stored in the E2PROM (assuming there is one!) has become corrupt?

Re: HP 85044A T/R test set part - Cabinet Trim "zipper" - 08502-20007 - source or 3D printed copy?

Zipping is ok but the two files in zip
Not to be contrary Paul, but these are pretty conventional files. Zip
has been a multi-file archive format since its inception more than
thirty years ago.

I do not have a clue how to use
To list the contents:
$ unzip -v <filename>.zip

To extract all files:
$ unzip <filename>.zip

To extract one file by name:
$ unzip <filename>.zip <file-to-extract>

same goes for the un zipped file
In this case the STL (STereoLithography) file is a standard file in
the workflow for 3D CAD designs. The files contained within the zip
file are save files for AutoDesk's TinkerCAD.

FreeCAD is immensely powerful, but depending on how your mind works,
it may be the right tool for you and it may not. Myself, I've been
programming for a very long time (40+ years) and what could take me days
in FreeCAD might take minutes in OpenSCAD. Others may find it to be the
opposite.

I mention this because you presented "doesn't need you to know
programming" sounded like programming was something to be avoided, which
certainly isn't the case.

Do you know how to program and are more or less comfortable in C?

I'd strongly suggest OpenSCAD, which has a programming description of an object, and is well suited to constructive machining.? It does very well on geometric shapes, and less wonderfully on organics.

Cubes, spheres, cylinders, intersections, unions, differences. There's a lot you can do with such tools.

Open source

Free.

Sadly the CLIP is not going to help you with the power supply, when you crack'er open you'll find two COTS switchers in there. One powers the oven for the high-stability oscillator and the soft power on, the other one powers the rest of the instrument, and the CLIP has schematics for neither one.
Thankfully I found that a full recap just fixed it(TM) in mine. I don't remember how hard it was to get at the PSU, but you might try just tacking a new cap over the 5.2V smoothing cap for a quick and dirty diagnosis.

I just went looking for photos, and it looks like the PSU drops out the bottom of the instrument. There's a "filter" board downstream from the PSU, and it's chock-a-block with inductors and smoothing caps, which is probably why no ripple shows at the IO board even when the PSU caps are gonsky.
