Anyone looking for a €1000 plastic case? https://www.ebay.de/itm/114972031453

McBryce.

You would be too late for a Telequipment Oscilloscope Type D1011 front and back outer cover, which sold for £100 even though “I have no means of testing this unit”   .

There are lies, damned lies, statistics - and ADC/DAC specs.

There is a Keithley 2602 SMU offered by zhoefler in the bay. Starting bid: 1190,- EUR (NAWTS)

https://www.ebay.de/itm/403162060138



I give up. What is a system source device used for?
A digitally controlled power supply that can also measure it's voltage/current with 6 1/2 digits. And it's "4-quadrant" so +- on voltage and current - which also makes it an electronic load.
A true "swiss army knife". And two of them in one case! These range up to 20V/ 1.5A and 200V/0.1A. Also, they are priced like a small car...
These are the original non-letter units, long out of service. I have a similar "A" unit, but these are out of service as well. Only the newest "B" units still get service from keithley AFAIK.

Edit: I should add that they are superior to a normal DMM, as since they are power supplys you can set the current to zero - as long as you are inside the +-200V compliance range "no" current will flow in/out of the device - which makes them a lot higher impedance (infinite in theory) than the 10Meg of the usual DMM.

For anyone with faded or faint engraving this might be worth a look. eBay auction: #401120957438 available in other colours too.

I have done a fair bit of trawling around for my Height Gauge refurb to go over the engraving and it came up very well regarded across a lot of sites and discussions. Same sellers product range is well worth a look too lots of interesting pliers, small hammers and bits mainly aimed at jewelry but plenty of cross over and they stock Xuron and Lindstrom.

Tube inbound so there will be pics and follow up in a couple of weeks.


How timely, I need to do just that on my 575. Missing red/black/blue paint on the test pod, was wondering what to use... cool that there exists convenient pens rather than having to a whole can of paint.  Looking forward to your feedback.
Would need the colour to be custom mixed though, to match the surrounding / non-faded paint... hoping the companies who do these pens also offer a customization service.

The 2602 is a dual channel model.
Those devices combine several devices in one case which is very useful for automation. It saves also a lot of bench space.
The 2600 series has:
- precision power supply
- true current source
- electronic load
- arbitrary waveform generator
- DMM (5.5 digit I think)
- I or V pulse generator

I've attached a data sheet of the 2600 series for convenience.

So if I wanted to measure the current required to make a fruit flies wings vibrate this would be my "go to" instrument?  ;D

If you are going to play "What is it" try this one. Its a part I have and yes that is an SMA connector on the end.

A pitot tube?

Beware! We had quite a few of these "always on" - after only a year a considerable number had gone bust; not only faded but missing lines and various glitches  :wtf:
In general, blue OLED have the shortest lifetime of the "phosphor", yellow has AFAIK the longest.

You used to be able to get that stuff in every colour under the sun, probably still can if you search hard enough but it's become a little hard to find presumably because of lot of engravers of labels and the like switched over to that laminate with the colour pre-built-in in the middle layer. Or, you could raid your kid's crayon box, or the PM's speechwriting materials.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

LOL see that's how you get out of jams here in the TEA thread. If anyone finds what they perceive as a "mistake" (which happens quite often here) you just say it was done deliberately for {some reason} or for {some sort of test}. Who can say you're wrong?  :-DD

Hmm OK, will search hard then ! I fear I might have to get paint custom mixed though, in the end, as I find it highly unlikely that some thing off the shelve would match the Tektronix colour closely enough to blend perfectly with the remaining/good parts of the face plate.  I fear this could become a bit of a rabbit hole for me...

It looks like it's got 2 distinct "ports" / tubes to let the air in. And it's Robert so unless he is pervert and is on purpose trying to mislead us, then it's probably an aircraft part.  So.. some sensor in an aircraft that takes air in. But it's not an air speed / Pitot tube sensor. So.. maybe a sensor for an altimeter ??

Yep these days multi coloured/layered plastics and metalized films have really seen proper engraving hard to find. Lasers Rule >:D

Are you sure Boris can hold a Crayon or does he more likely eat them?

As we've ruled out pitot tube (and presumably anything close and pressure related) then my list would include liquid cooled load/terminator, a flow cell of some sort, or (low probability from the connections) some sort of GDT type lightning arrestor.
