Dear insiders, I have some probes to identify (what is it exactly)

1.)  Wandel+Goltermann TK-3 BN 207/2  10Hz - 1MHz U<=3V, 100kHz: 20M 7pF / 1MHz: 1M 7pF

2.) (unknown)  P 851/75-93  a large black anodized Aluminium Case Probe, UHF jack

3.) (unknown)  P 851/50-93  same

thanks for informations.

The W&G ought to belong with one of their selective level meters, as they are the only W&G instruments I know which would benefit from a probe. In that case, it is almost certainly for a 75Ohm input. Which connector does it have?

All those numbers appearing with the P851s are well known Impedance values. So they are probes with integral minimum loss pads adapting 50 or 75Ohm sorces to a 93Ohm input?? I have heard of 93Ohm systems, but not of an instrument using that for input impedance.

thank you

Logic probe?

fine, then you can bring your H3013

Got this on the printer so my silicone cables don't get chaffed 

Takes about 22m of filament with 4 layers all round and 25% infill. In the zip file if anyone else wants to give it a go too.

Nice! So please answer me some questions, as I would give the technology a try before jumping into the hole headlong.
What did that cost you to make (Material)?
Did you find that model or did you have to do 3d-CAD?
What is the material?
How long did it take to print?

It is my design done in Fusion 360 maybe an hours work or a touch over by the time I tweaked it and added all the fillets.

Still printing as of 3.30am but loks like it is nearly done. The slicer said over 9 hours ao like all FDM prints it is not a fast process. Material in this case is PLA but ABS or PETG would be fine too and they are also tougher but come with their own issues.

Material cost say 22m of a 300m roll. Locally we pay about $20-22 AUD/roll so circa $1.60 AUD which is about 1 Euro. That plus some power.

You would never get rich making parts but it gives flexibility of design or now the model is done print another if needed.

Finally time to get some Zzzz after a very very long day and night

Gaze at the pretty neon glow and breathe serenely.

Amazing picture! Those Nixie tubes in dim light 

Can we have it on better resolution?

This should get you to the original photo:

I think it should be downloadable; if not and you want a copy let me know and I'll PM it to you or something.

-Pat

Got it! Thanks

@Martin.M: Isn't there some logo on the forward smooth area of the 'P851' probes?

You are most welcome!

I have a new wallpaper

I want to go to Martin's house and play with all his cool stuff. 

I wanted to ask Martin if he has an album of all his stuff. I've seen his Tektronix restoration blog, but seems like he has way more awesome stuff!

He's definitely got some great gear!

Blimey. One for Specmaster... Just took the PC case I bought to bits. It's only a Micro ATX but there's 1x 5 1/4" hole, 4x 3.5" disk bays, 4x 2.5" mounts and the board takes 2x NVMe SSDs. Expansion worries sorted

I’ve got a dwagon-cave!

*~...a cold, dank, dark dwagon-cave. And Martin has all those warm glowy valves & nixies...~*

Hey Martin! Can I come play too?!? I’ll even bring bacon we can cook over the Tektronix’ glow!!!

mnem
No, seriously. I have like 15 lbs of frozen bacon I’ve got NO IDEA what to do with; local food bank won’t take it because it’s past expiry date.  I’ve literally been eating bacon & ham for WEEKS... 

[bd139]

Wear it!

Whaaaaaat...?

[tautech]

Wear it!

And dwagons !

I like my women and I like my bacon but not in the same snack. 

[Martin.M]

at the workbench 1 I have left side a Tek549 Storage and a 533A.



the 549.




the right side of the table, there are a 535A and a 585A 
So there are 4 glowing Tek directly at the place.

Well, the PM 3218 arrived, about a week late as the vendor had a brain fart and went on holiday for a week...

Delivered by the Herpes, left on the doorstep in fact, despite requiring a signature, the screen bezel is now a 100 piece jigsaw puzzle, and the control panel is shaped like a satellite dish...



Some of the inner knobs are jammed, many are rotating the whole pot/switch, and there's a certain level of funkiness occurring when the panel is moved 

I always knew I'd have to re-cap it and generally check the innards, but this... the case is crusty af as well, looks like it was stored in a damp and draughty shed at the bottom of the garden for the last 20 years 

At least it works, at least in general...

A couple of pics to show off the dual timebase:


100KHz sinewave (allegedly)


1MHz squarewave

The squarewave looks horrible on my Tek 420 as well, not sure if it's my crappy makeshift connections or the sig gen (probably both  )


The vendor has told me they had it 'covered' with SHermes to the tune of £35, so will look at screwing some pennies out of them to cover the insult to the CRO gods

[med6753]

Wow, that sucks. How do those dipshits Herpes stay in business?  Although I'll bet the packaging wasn't that great.

Glad we don't have Herpes over here.

[Martin.M]

they are not careful with packets.

549 is the scope with the golden CRT

Yeah, that really sucks.
But the padding is the sellers job..

..or it's the job of Pitney Bowes: 
Waiting for an Agilent 3499a switch control system 5-slot mainframe shipped through ebays global shipping program and will be delivered by herpes locally.

(Danger of damage)²      

Well, hope is the last to die.
