BTW Nuclear torches (flashlights) actually exist:
https://www.survivalgear.nl/us/betalight-betalight-torch.html
They loose half their brightness in 12.5 years. Availabilty and licence requirements vary by country. I have a couple of betalights. One allows me to find the light switch amongst all the TE in the loft space.

At university the original build of the Student's Union/Refectory building used big betalights for all the emergency exit signs in the building. The Student Union had the official university builders in to remodel the big room used as a venue and in the process those builders skipped all the betalights, cracking some in the process. I bubbled them up to the university's radiological protection officer. Aside from all the trivial sources you'll find in any University we had a sodding huge 60Co source buried 20 feet below and behind the science block, so his job was more than a 'tick box' effort. He was a decent sensible bloke who was quite reasonable to deal with, but (rightly) completely intolerant of people who were stupid with regard to flaunting the rules. I'd love to have been a fly on the wall while he tore them a new one.

Indeed, I was throwing someing in a WEEE skip a few years ago and saw a radar T/R tube in there. It was a tritium doped type. I dug it out and gave it and advice to the skip "owner". The problem was not the amount of radioactive materal but the fact it had a warning trefoil on it. scrappies have had it hammered into them to call the authorities if the fnd anything with a trefoil. This was becuse of a couple of incidents wth larger sources. A multi-million dollar clean-up of a foundery grabs more attention than somone getting radiation burns. The T/R tubes declared initial activity was 1Bq below the quantity were it could be disposed in land-fill. There is a requirement tha the radiation warnings are removed and you have to make sure it's landfill not incineration and there is a limit to how many per cubic mer of waste. The responsible person decided not to belive me or my reference to the current disposal route, they paid  consultant to dispose of it. I'm 100% certain they scraped the markins off and put it in a skip going to land fill.
Not an option for Beta lights, theay thousands of time higher activity than the landfill limit. Either storag for 125 years or tritium recovery for them.
To keep on topic, some test equipment and a fair few radio bits use betalights.  To be honest a bit of tritium gas from a broken betalight would not bother me too much (ventillate room and drink lots of beer (it increases water exchange in body reducing the biological hlf life of any tritium that bound to water.)
The Nickel 63 foils used in some lab instruments and chemical / explosives detectors are a bigger risk. They corrode shedding particles, and the low energy beta is hard to detect but can cause a lot of biological damage.

Who was it that said that the Type 310A was a hot box? They weren't kidding. This little SOB has only been on 15 minutes and already throwing off tons of heat...even with the covers off.

I've noticed a few issues. The trace "blooms" and goes out of focus if you crank the intensity up. Probably needs HV checked and adjusted. The 50mV Vertical range is FUBAR. Trigger seems a little odd in the way it operates. Already mentioned scale illum dead. But considering the filthy mess it was this is pretty damn good.   :-+

Nice. I remember SINIX on some university computers ...

I wonder just how many of the newer scopes would do that when they reach the same age, probably zero  :-DD

Yes indeed. I've decided I'm going to keep the SDS1202X-E until it snuffs it. I reckon ~5 years and it'll brick itself irrecoverably somehow.
:bullshit:
After a bite weren't you ?  :P  :horse:
Oldest units I have 'out there' are a bit over 7 years and still going strong. Not X-E though but some earlier and much less well featured incarnation.
They weren't fan cooled though which IMO are more of a ticking time bomb.  :popcorn:

I use Malwarebytes, it has almost zero impact on the speed of my PC and is constantly scanning in the background and will often pop a report in the bottom right of the screen giving the results of its back scans. Take a look at this, I used to have the free one but it was only basic and then I upgraded to the premium single user with a voucher after I had an email from a scammer who claimed they had details of my passwords etc and demanded payment in bitcoins or else. Probably got my details from one of the hacks on various companies systems. Passwords have been changed as a precaution though. Malwarebytes also includes anti ransomware as well.
Malwarebytes doesn't score well in tests compared to others.

It's not undocumented, you just haven't got the right version of the manual* for your later PSU, I've had to change quite a few toggle switches in boat-anchor grade HP stuff, they often fail open circuit.

*I have the same problem, the manual I possess is never the right version for whatever revision of TE I'm working on, followed by lots of head-scratching trying to work out all the design changes due to obsolete Ge components or elf"n"safety non-improvements.  :phew:

True! There probably is a proper manual somewhere. 

This toggle failed with "no toggle" but with a suitable set of pliers it can be told to switch on, so while it failed while being open circuit it did not do so for good. Of course I'm replacing it -- just had to find a non-metric switch. They all are for 12mm holes these days, but I need just below that, 11.90625 mm or 15/32". (the calipers say 11.9mm, I don't have better than that, but bc gives that many decimals for said fraction.. )

Also, modding to DPST from SPST is a Good Thing. I like that. I'd just want it to be documented in my manual.  :-DD

Edit: The revision Keysight publishes does not mention the DPST switch...

Today's score: A 500VA 1:1 220V toroid transformer for isolation purposes. Free. Haven't checked it out, but hauled it home. It never hurts to have an isolated mains supply. I'd really have liked for it to have a centre tap, but alas. At the price, though, I'm happy.

That was the first thing I suspected when spotting your pic of its trace. Burn in first then adjust the HV.

That nickname was kind of self inviting. I've "invented" it too, about the same time I called XENIX "Sehnix".

Well of course. Who knows how many years this scope sat unused and collecting dust/dirt. It's going to have a few issues that will need to be addressed. But once I get done it will perform as near as I can get it to factory specs limited only by the equipment I have available to calibrate it.     

And I already fixed one issue. It was an operator error. Since the scale illumination control also functions as the power off/on switch the max intensity for the scale light bulbs is full anti-clockwise, not full clockwise as is normal and you would expect. The bulbs are fine.  :-+

I give up. After multiple attempts to convert the translated QRV-HB100 article to .pdf without copying it to a fucking Word document first, I cut my losses and just zipped the .html. :palm:

EDIT:   And now I see that the problem was Gurrgle all along; they have some DRM crap in the document so it will only open in a new window at Google Translate. The .html below is useless. |O

I am fine if you have fun.  8) What I wonder, however, is in which holy grail Tek museum all these beautifully and fully functional instruments will land. And, who is gonna come and visit these museums ? My first guess: Old farts as we are ourselves.
Best example: Wellenkino (largest collection of tube based Teks in perfectly working order I know of). Awesome but futile. I love it.  >:D

Nope. The problem was Gurrgle all along; they have some DRM crap in the document so it will only open in a new window at Google Translate. Doesn't matter what fucking browser. Doesn't matter what print to .pdf plugin either; I tried several.

Correct, I can at least open the document from your zip file, in a new window any form of printing results in page 1 only and then at almost double the size so only the left side prints to pdf  :palm:

Blowing like a right SOB here today and not wanting to be 7m up a ladder so grabbed the boi as he was passing in his digga and worked outta the bucket.

Not been formally shown how to do the powerline bindings however it looks fairly close to what was unwrapped.  :phew:

No, it opens a new window/tab, then reloads the original page from Google Translate; not the local document. Try and print it to .pdf; you'll see what we're talking about.
