3457A calibration data dump / restore
Hello,
?
I have a very nice 3457A which has a 40-year old battery. New batteries are quite inexpensive and easy to find, but I'm quite scared at the prospect of replacing the battery without first dumping the calibration data to a file, and having a way of reloading it if anything goes wrong during the replacement process. Someone already tackled the problem of storing the cal data on a PC () but I couldn't find anything about how to restore the data from the PC to the 3457A if the data is lost.
Right now my 3457A is sitting there with a battery which is 40 years old, and counting ...
Any help or pointer(s) would be sincerely appreciated !

Re: I need a new/used lab computer
Re:-
Do you have anyone in your environment with a not too old laptop?
Get it for a box of cigars, install an SSD and Linux Mint. You're
back in business!
There is nothing wrong with using Linux for instrumentation.?
But...
That is likely impossible with a laptop, if you have a PCI GPIB
card, plus though it can work with Linux, the bridge to cross is
narrow and wobbly.? (Steeeep learning curve!) ? Then, any existing
software that ran on Win7 wont run natively, and even if it does
in a VM, may not work with the PCI card known to the host.
(From personal experience, with an XP VM on Linux, the NI
GPIB-USB devices DO work with software and NI drivers running on
XP in a VM, as you can make USB devices visible to the guest OS.)
Nothing wrong with Win 7, so long as you don't let MS muck it
up.?? Anyone using it (or later MS OS's that are out of official
support) for anything less than trivial, that can access the
outside world, should perhaps consider:-
or:-? if the above gets broken. ? ??
That goes to the above address.
Not used it myself, yet, but is recommended by Mr Gibson of
grc.com.?? If you know who he is, nothing more needs to be said.

Re: I need a new/used lab computer
I haven’t tried to do anything useful yet, but I did succeed in getting a raspberry pi 5 to see an NI PCI-GPIB card hoping so a compact HPdrive system with the advantage of being able to ssh to it rather than being a microcontroller based solution.

About PCI(e) passthrough - I tried to breathe some new life into an old PCI NI AWG card that supposedly only works with Windows XP. The card works flawlessly on a native XP install on the same machine (a PC from the 2010s). My thinking was that
I could install XP in a VM and set up PCI passthrough to gain "direct" access to the card from within the VM (that would've made the entire setup enormously more useful for obvious reasons, practically meaning that I could use a single computer to manage all
the devices on my bench). However, although the virtualized XP recognized the card, the NI software couldn't initialize it the same way - or use it altogether. I've verified that the hardware supports IOMMU and it's indeed active. Other users had similar experiences
on the NI forums. I didn't have more time to investigate and I left it at that and accepted defeat for the time being. So, as you said, YMMV.?
That’s not absolutely true. One can use a thunderbolt equipped laptop with an external PCIe cage and a PCIe to PCI adapter or a PCIe 488 card.
It is even possible to use a virtual machine with an older OS than the hardware supports and use PCIe passthrough of the PCIe to PCI bridge to expose the card behind it to the virtual machine.
Due to lack of many necessary parts to support parallel ports, running things like E-cal that requires a GPIB port and a parallel port is likely not really feasible on modern hardware.
Another interesting problem is that it is possible to have hardware too new to run an older OS and you can find things like video drivers simply don’t exist, or USB ports not seen which can lead to no keyboard/mouse. Some can be worked around,
some not.
I’ve fallen down that rabbit hole and had some wins, some losses and some I could pull off but would be hard pressed to replicate or help someone through.
Ultimately, some things that are possible aren’t economically viable or cost so much more than alternatives.
The higher cost and more limited options for a TB capable laptop plus all of the necessary adapters and extra hardware can easily add a few hundred dollars.
Looks like he needs a PCI slot for gpib card. Would have to go to USB to GPIB if he went w a laptop.

HP 8568B Instr Check Light?
Looking to purchase one.? It shows no display on the screen which I can deal with, but I can't seem to find in the manual anything about the bottom Instr Check lights.? The left one stays on.? Any knowledge about what causes this?

It has been a while since I’ve had to use it, but when using PayPal shipping (USPS), have done electronic customs declarations and electronic invoice where I put in the quantity, description, weight, HSTS code, value, etc and had no trouble with.
It seems to me two copies went in the external pouch and I put a third inside the box for good measure. It seems to help if their job is actually harder than taking the easy way if every piece of information they could want is readily accessible without opening
the package.
Going the other direction, I remember a fun transaction where FedEx lost an e-cal module coming from Mexico to me in the US … after it went through customs. I raised a real stink firm and polite at first and ultimately after sending them a photograph
and description of what they were looking for and conveying the sense that they really wanted to find it rather than pay a claim for loss, 13 hours later it was found, and injected into their system as an overnight and I got it the next morning.

I received from Digikey five or six parcels during the last weeks without any problems. Each always over 150 Euros.
?
I sent a small letter three weeks ago to the US with DeutschePost containing 2 pregrogrammed gals and 2 programmed flashroms (value 10 Euros) as a gift for the receiver, but it was opened and returned with a remark like '...returned... changed import/customs regulations...'

SMD S461, L266 on DC-DC converter - HP 02463-80901 ; what are these devices for?
HP 4263B LCR meter.?
It worked wonderfully for the past few years until last month when a total blank of display at turned on.?
Later on it had been turned on once again with correct measurements but one of the red LED 5V was lit.
Now it was totally dead. I suspected that the Japanese made DC-DC converter 02463-80901 was the culprit since no output can be measured from this unit.
?
There are two surface mount devices marked as S461 and L266; four legs components with plus on two pins. I had never seen any SMD like these. Are they diode or a twin capacitors? S461 was connected in parallel so it might more likely to be capacitor?
?
Basically my problem of 4263B was exactly as the same as the following post: blown L266 with evaporaied carbon deposite??

That sounds quite bothersome! I'm under the impression that a lot of the documentation/declaration requirements depend on the carrier and service you're using and generally, more established shipping companies seem to be able to abstract the process a lot (although I can't say with confidence that it's the same in the UK, especially post-brexit).
I see no reason to believe it is significantly different in other countries. In particular those UK pages note ??? Commodity code in other countries
??? Although many countries have signed up to the same classification system, only the first 6 digits are used worldwide and product specific decisions are particular to each country.
??? If you rely on the commodity code from an overseas supplier, you’ll need to check if the treatment is the same and how much of the code applies in the UK.
As for Brexit, it is mainly a pain for, UK<->EU trade, but otherwise no worse for any other small country. Having said that, there are complications for goods going to/from/through Northern Ireland since that has a big land border with the EU.? That border is traditionally very porous, with some buildings straddling the border. That's far from unique. e.g. see "Pastoor Van Herdegomstraat 19, 2387 Baarle-Nassau, Netherlands", then slowly zoom out until all of Baarle-Nassau is visible. Isn't history wonderful.
? In general, package forwarders in the US only require a short abbreviated "laymen's terms" description of the contents that they don't seem to challenge in any way at all (I've brought over instruments, LA and scope blades for the 16700 mainframe, consumer and industrial electronics like servo drives and motors, teach pendants for robots etc., mostly multiple packages consolidated into a single shipment). Depending on the arrangement, duties and VAT was either billed and paid for when placing the shipping order _or_ I got notified by mail with the instructions when the goods reached the country, then after I paid the duties, it cleared customs and it was on its way to me. Gabor
I'm sure that's the case. Pragmatism almost requires that such short cuts are taken. How lucky are you feeling today? Or when there is an increase in "retaliatory tariffs" and "long land borders" :( ?
For the avoidance of doubt, I have not been bitten yet except for the narrow escape I mentioned with the 1000inch mahogany Fuller calculator.
?
Some observations from the UK. TL;DR: fleabay's GSP is wonderful, much better for me than my shipping my sales directly.
When I've bought something direct from the orient, e.g. a BusPirate5 or Digilent Analog Discovery, the courier won't deliver it to me until I pay them 20%VAT/import duties plus ?20 admin fee. Those often make it better to buy from local importers.
Import/export regulations hit more than "electronics". Somebody in the USA put one of my ~100yo Fuller calculators in their fleabay basket, but fleabay wouldn't let them buy it. The reason is unclear, but is probably that I had stated it was made of wood and metal. Apparently the US prohibits imports of wood. I'm glad fleabay prevented that sale, because if fleabay's GSP shippers or US import agencies had detected wood, it would probably have been summarily destroyed without returning it to me. Guess who would have lost out.
As for batteries, it seems that batteries which are an integral part of the equipment don't provoke the shipping immune response. Caveat: I haven't looked at shipping equipment with "modern" lithium batteries, nor recently shipped battery powered equipment overseas, nor "naked" spare batteries.
As with any tree-shaped classification scheme (e.g. Dewey Decimal for
books), selecting the customs code is not only
arbitrarily complex but also ambiguous and ever changing. ISTR some types of fast Tek scopes with MCP CRTs were classified
differently for export purposes: 2465 OK, 2467 sometimes not OK. For the UK, the anti-insomnia "medication" is?
? For "oscilloscope" that leads to and if you look down several pages you find imports require 20% VAT and in some cases 35% retaliatory duties. Getting those ever-changing duties correct is something that will require vast numbers of customs agents and border checks and/or couriers that act conservatively because they don't want to jeopardise their standing with governments. Wonderful, just wonderful.
No doubt other countries have similar tools.

Re: E5052A Power On Test (3.3V Bus Supply)
Hi Jeremy,
Nice noise floor. You are still at 20dB/decade at 10Hz slope so playing with sustaining amplifier and reducing Fk might improve things a lot.
I will email you, perhaps it's getting a bit off-topic.

Even worse when something sent from the UK to the US for repair
(under warranty.)
On it's return, we would often get charged full UK duty/taxes etc,
as if it was "a New import", even if the US office managed to get
the paperwork straight (rarely) AND send it back via the exact same
route but in reverse!.?? That's a UK custom's rip-off thing, and
there is no way to challenge it for small co's and individuals.
It's as bad if anyone ships from the US to the UK using the USPS.?
That is then handled here by Royal Mail.? They add import duties
(even if the commodity code indicates low or zero duty) then
exorbitant "handling charges", and our 17.5% VAT on top of the lot.
So, something that cost, say, $20 US on eBay, I end up paying over
?100 UKP!? Has happened twice to me.
Then there are the US sellers who list "international shipping no
problem", do NOT exclude the UK.? But flatly refuse to communicate,
though take my money!?? That's something eBay is good at, getting my
hard earned back in those cases.
Oddly, DigiKey can send me a high value (100's of $'s) parts order
to my door, overnight, seemingly with impunity and minimal charges!?
I forget what they declare on the package.? And no, it doesn’t come
from a bonded warehouse in the UK, as it's smothered in stickers and
stamp markings indicating it did travel overnight by air!?? So it
can be done.
We (in the UK) also now get screwed by our own idiot government
since Brexit happened, moving anything between UK and EU (Including
Ireland) either way, now costs a fortune and takes an age, as there
are not enough people to handle the paperwork.? It's as if they have
not heard of doing things digitally.? Hence, there are sellers in
the EU who will now not sell to UK buyers.
Worse, a large proportion of our food is imported from, or via the
EU.? Result?? High prices, and very short "use by" dates.
"Modern Life" eh...? We're rapidly reverting to being "The Sick Man
of Europe" like we were back in the 60's.
And you don't want to know what we pay for fuel and energy in
general!
Regards to All.

Make sure to write 'no lithium batteries' on it or it might get returned.? Ask me how I know...
