Re: ESA instrument adjustments - reverse engineering
Thanks Dave,
I'm shamelessly bumping this topic for those interested.
Over at the EEVBLOG thread:
I recently posted a description of how to adjust your preselector YTF on the E44xx instruments
I posted a scan of all registers between 0 - 1000
Other participants are doing some intense thinking on how to give the thread proper attention and retention of the findings.
Best regards

Re: 8566B inconsistent amplitude
So far I been unable to duplicate the problem I had before, the amplitude is completely smooth and stable for some time now, so, I think am probably good.
Boards I reinserted relating to this post if anyone is interested
Display section
XYZ display driver board
A3A1 - A3A9
A1A6 - A1A8
RF section
A8 Recifier
A17- A21
Electron microscopes are fascinating instruments, never seen one in person but I find it amazing that they can resolve detail down to the atomic level!

Re: Using ECAL with E5071 VNA
Yeah, ESD damage can be there but has not yet caused a failure. Very hard to spot functionally without very careful measurements or a SEM, at which point you¡¯ve destroyed it anyway. ? ?

Re: Torx head variety of top/bottom cover retaining screw
My first encounter with HP was with the old 8620 and 8640 series , there were tons of them on the market in Germany from military surplus , next came the 8754 and 8756 and then eventually a garden variety of 8753 analyzers and 8673 as well as 8340

Re: OT: SEMs, Re: [HP-Agilent-Keysight-equipment] 8566B inconsistent amplitude
SEM people... Well, there goes the neighborhood... The SEM I am currently working on is a JEOL 6100. The way I see it, SEM's are the perfect boy-toy, even for girls... Vacuum pumps going piddle, piddle, piddle, raising a haze of oil, diffusion pumps to keep your water bill up to a respectable level, high voltage, x-rays, LN2, expensive LaB6 emitters, sputterers to coat exotic metals, and carbon... and if you are lucky, a forest of TTL to keep your AC busy... It doesn't get any better! -Chuck Harris On Thu, 16 Jun 2022 17:55:48 -0400 "Dave McGuire" <mcguire@...> wrote: On 6/16/22 11:26, ChrisBeee via groups.io wrote:

The instrument I'm working on now is an antique, an Amray 1200

My regular instrument is a much more modern Topcon ABT-32, with a
digital imaging front end.
I have a JEOL SEM-T330A in my lab that I recently acquired. Very nice! I recently picked up a JEOL JSM-T300, also from a
university auction. It was local and cheap, and it came with
schematics (!) so I couldn't pass it up.
Still a lot of things to do until I will
dare to fire it up. It sat unused in a university lab for a couple
of years, so all fluids including lubricants must be replaced.
Especially the transformer oil does not impress me, it is degraded
and likely will facilitate arcing inside the tank. Yes, bad HV tank oil is definitely a risk. Hopefully it's not
hard to get.
Once running, the T330A should be a
great instrument for the usual household applications... ;o) Of course! :-) My SEMs are in a working lab now, but my first
SEM, about 25 years ago, was in my living room. I was popular back
then. :-)
I got acquainted to a guy in Brazil who also bought a T330a
recently, so we are already two for this instrument type. Do you by

I'm thinking about creating a new one for SEMs in general. I'll
email you about it off-list.

Re: Torx head variety of top/bottom cover retaining screw
I tracked down the part number for a Torx variety of the cover retaining
screw: 0515-1245. This is directly orderable from the Keysight parts
store:
The price is pretty outrageous, but it's there if you need it. The
retaining ring (0510-0043) is also orderable, though this is less useful
as you should be able to just reuse the one from the existing screw.
A bit more background:
As far as I can tell, HP used two different types of screws to fasten

above is an M3.5 screw.
I'd previously investigated modifying existing screws for this purpose
but I don't think that's possible. The OEM screws have a thicker
diameter in the region where the slot is cut than normal screws. Even if
you got something to work I'd expect you would just end up with weak
screw. But someone who knows more about this sort of thing can weigh in.
I use the Jonard Tools CS-1022 for replacing this screw-retainer ring
assemblies:
It works great.
Hopefully someone else finds this useful.
Matt
PS I reached out to Torx Products a while back about this and they
claimed to have no knowledge of P/N 920-46590-570. That could be just
due to poor internal records. I ordered a few of the 0515-1245 and IIRC
they came from Singapore. I'll see if I can find a company name.

Re: Does anyone have a copy of the HP Basic for Windows INSTALLING AND USING manual
Sorry for reviving an older thread but I did want to say that I'm using HP BASIC 7.1 with an NI GPIB-ENET/100 controller without issue.?
The first thing I did was to setup then GPIB-ENET/100 using the NI Ethernet Wizard and confirm that it was operating using NI MAX. Once that was set up I then installed HP BASIC 7.1 and made a change to line 340 of my AUTOST program:
340? ? ? ?LOAD BIN "GPIBNI;DEV GPIB0 ISC 7"? ? ?! National Instruments GPIB boards
I think this is a binary file on disk so I use RE-STORE to save it again (if it is an ASCII file then I would have used SAVE) - Once I did that it's been working fine with the GPIB-ENET/100.
I'm hoping to upgrade to a GPIB-ENET/1000 at some point but everyone seems to want to get around $750 for them on the auction sites so I'm waiting out for a better price...

Re: HP 8594E downgrade after battery replacement
If you care about setting your serial number back to 1870, you can run
the command:
??? SERSET 1870
via either the GPIB port or the EXECUTE TITLE facility.
In the service manual, the command:
? FACTSET 11023,1
sets the analyzer to a C series.? You could try "FACTSET 11023,0" to
see if it will put it back to an E series.? Just a guess.
