Test Equipment Anonymous (TEA) group therapy thread

I'm trying but I guess it ain't working. I have to run out and brave the disease stricken world so this will be my last post for now.

I'm convinced this scope has never seen any Gorilla hands and hasn't been touched since it left the factory nearly 60 years ago. The 1mV Vertical cal was dead nuts. 0.2V cal just needed a tweak. The sweep timing just needed a tweak too. The Trigger was fine as is.

100kHz/0.5v p-p. Vertical set to 0.1V/div, Sweep set to 5u sec. The camera introduced some parallax error. The sweep is indeed lined up across the entire screen.

I'll do the compensation tomorrow.

over here they required school kids to do indoor sports in large groups.
Even those who already have asthma and similar ailments.

And they openly said that they would sacrifice a couple of kids (and parents) ...

now I have some special love in my heart for these politicians

Forget the ballot box. It's broken. Between two-party systems and voter manipulation (social media and press that is) it's gone.

As I believe I have pointed out before, I am currently available to take the post of Dictator for Life. The downside is that you'll lose the Natural History Museum to become my London Pied-à-terre, the upside is (1) no taxes on test equipment, (2) 'green' tax rebates on second hand TE, (3) no matter how useless I might be, I'd do a better job than the current mob. Also the mandatory televising of the Trafalgar Square scorpion and snake pits will make, I'm sure you will agree, a welcome relief from the parliamentary channel, Eastenders and Big Brother.

I am more for blood eagle. Or keelhauling. You still have aircraft carriers that could be repurposed, don't you ?

I think I would make a pretty good kaishakunin.

Cerebus, it is not just school kids that are helping to spread this, but college and university students alike, they could continue their studies at home online. They are after all, having to do this in the campuses anyway, being confined to their rooms, learning online. The are required to there in order for the uni's to collect their rents from them, once again we see the economy put ahead of people's safety and common sense.

Indeed. The difference is that every community has several schools whereas the universities are relatively isolated, as are the students, who go home once a term, whereas schoolkids go home every day (and to their Gran's and their neighbours, and the local shops and so on). Even in the local community, there were times I went weeks at a time without leaving campus when I was at university. Universities compared to schools, are a trivial vector - that doesn't mean they should be ignored, but in terms of what's most likely to be damaging to the population as a whole it's the schools that need tackling first.

Yes, while a lot of this is true, they still have to get from to the university in the first instance, and then they have to make that journey back again at the end of terms etc. You might well have been a model student when you went, but sadly that is not the case these days. Many of them have taken part-time evening jobs to help fund their education and there are still groups that go out for exercise etc. We have a quite a large Uni here, and you can see groups of students going to and from their rooms on the campus and also many of them live in houses in the vicinity which are home to many students sharing rooms etc, only the more affluent students can afford their own room. These places are hot spots of infections and carriers just waiting to happen.

I have seen such groups of students, most without any form of face coverings, while on route to pick my son up from work when he is on the late shift at his place of work, otherwise he would have to walk among these students and increase his risk of contacting it above the risk he faces at work.

Road Trip to the middle of nowhere. Might be worth dropping the seller a message if anyone is keen eBay auction: #154269650090 $1 USD pickup only.

Good effort, Bean.   Just need to tweak the geography element.

From this end of the planet a bit of an epic and for some reason I feel safer here with our National Farce than that of the source country  Kansas is about 1500 Miles from everywhere in the USA 

I actually bothered to map it... 20 hours one way.      But.... a little too close to the heart of Dumbfuckistan for my tastebuds.

Tejas is a black hole.

I drove a van from the UK to Germany once to pick up an ex USAF gas turbine air start unit. That was a two day trip. Stopped by Helmut Singer' on the way and got some of his clearance stuff (yes it was years ago, Oct 2002)

You do not by any chance know Michael Ross out of Cambridge who was collecting gas turbines ?
He later emigrated to the US and his last whereabouts where Mamaroneck, upstate NY

No, name does not ring a bell. I was more active with turbines when I was down south. Only recently got one since I moved to Cambridgeshire and not had a chance to do much with it yet.

The TTi TG2511 arrived today and is currently baking by the fire.
It arrived in a most satisfactory box, which I think I will pack the Solartron 7150 into, ready to be shipped.
If any of the regular TEAtimers want it, I'll let if go for £60 + shipping, though I'll be putting it up for probably more like £75 or £80 in the BSW part of the forum.



Several kindly individuals stepped in to save me from myself today; I had the maiden bid on a Tek 754D, and the seller had it as collection only, or buyer organised shipping.
Fortunately I was spared the inconvenience of this by the bidding all happening in the closing minutes, and my £200 was thoroughly eclipsed by the final £570 price.
That seems a bit high to me, but w/e.



Back at work today, and the shit-show continues, this time at the vaccination station we're putting a supply in for.
Given that's all we're doing for it you'd imagine it's a simple job, and the possibilities for fuckups are surely small..?
Nope, the list of problems is longer than the list of things that aren't problems.

Welcome to The Council, it gets worse here every day,
You learn to shrug and turn away in the city where we play.

Oh, and one of the few remaining sparkies handed in his notice today. That will take us down to 7 men in projects, and 6 on maintenance, with 6 apprentices and 2 mates.
For a City Council with over 8 thousand employees (not counting schools), and idk how many buildings (not counting schools), with an area population of over half a million.
There isn't enough popcorn in the world for this...

@AVGresponding, Why is the TTi TG2511 currently baking by the fire, did it arrive drenched then or what??

Sorry, but I never realised that you work for the local authority, somehow, I formed the impression that you were a contractor working on a council project. If they keep leaving like that you could be out sourced too.

There's sometimes no reason to leave the campus. There's computers, booze, usually a shitty SU nightclub, one or more shops, local pizza place and floozies. Plenty of time to to cause trouble there

Not drenched, but was left on my doorstep by ParcelFarce in sub-zero temperatures.



It's not impossible; they hived off all the housing maintenance to a semi-private company under the Blair regime, long before my time.
They have just taken on two new apprentices, and there's a legal obligation involved in that so they wouldn't be doing it if it was at all likely to happen in the forseeable future.
The pay is one of the primary issues causing us to lose the young ones who don't mind all that tedious working away if it means doubling their wage.
There is a pay rise in negotiation, which will take us to almost the going rate. That negotiation has been running for three and a half years now though...

And there we have it, the poor staff of those places would then become the unwitting carriers of said virus, it would make zero difference if you were an internal rebel or an external one, thank god your not currently a student at uni say I

And didn't the Chancellor say in the budget that public sector workers would once again be having a pay freeze  I'm so glad that the standard's committee also froze the MPs pay even though they elected to give themselves a rise

OK, I'm back and I'm going to leave my mini rant and then go do something constructive like watch TV. 

The USPS is indeed totally broken unless you are Amazon and kissing Jeff's ass. The scope filter did arrive Saturday....finally. But today I get a Christmas card from my sister-in-law in Colorado. Mind you, this is first class mail. It is post marked December 20th in Denver. Today is January 4th. Do the math. I just talked with her and she said she actually sent the card a week earlier. So apparently it took about 5 days to go from Greeley, Colorado to Denver. 

I told her next time send out the cards in July.

OK, it's time for some TEA stuff. We are wandering too far into dangerous territory but I totally understand why. Not a good situation.

This is the test set up to verify vertical gain, timing accuracy, and trigger. FeelTech function generator as signal source. The Siglent is there as a cross check to the FeelTech to keep it honest. Once all that's done then I will switch to the Heath IG-4244 Scope Calibrator to perform the compensation.

Since I had to access both sides of the scope it was much easier to set it up on the kitchen table. It was too big for either bench to easily do that.

I got lost at the point what the kettle is for. Could you clarify please

Could it be for a well-earned cup of coffee I wonder? I have to say that the Sigilent looks rather precarious balanced on top of that Feeltech signal generator, its a good job that my big arse or the Dwagons  scaley tail weren't there

It would be scariest if he balanced the 503 on top of the Siglent..

You neglect that campus included all the necessities of life, to-whit Sex, and Drugs, and Rock-and-Roll. Although I might have spent a fair amount of time in the library and in lectures I probably spent more time in aggregate in the bar, doing sound or lights for a gig, or trying to have my wicked way with some ingenue with far too much good taste to associate with someone like me outside of a university.

Nah, the 503 would just crush the Siglent to bits.

Been experimenting with the FFT capabilities of my TDS420A using the TTi awg, and confirmed what I suspected.
It's usable, but slow af, and the cursor is limited (horizontal or vertical, not both).

Some jitter observed on the awg output, so I decided to check the 10MHz ref out, and omgwtfbbq it's terrible Muriel, wobbling all over the place, around 0.67% either side of the centre.
Looks like I need a better reference oscillator in the thing.

[bd139]

It's fairly shitty and slow on all digital scopes. Some are worse than others. Siglent is least bad

To be fair, given its age and limited sample rate, it's respectable. I wouldn't like to try and use it for serious SA type work though.

I'm sure it'll come in useful at some point, and saves me having to buy an SA that I'd probably use once a year if that.

Woohoo, lockdown again, means I get the roads to myself when I go to work!
