Proposal to develop Insulin sensor submitted to the powers that be.
Now need to forward this to our CEO thru channels just in case some midlevel management critter decides that it's too much work to take a stand ...
This would be an insulin sensor that could be used in a personal device? That would be a game changer for diabetics!

This one gets nearer to what I'm trying to achieve:

And there's a thread here on eevblog:
https://www.eevblog.com/forum/metrology/dmtd-board/?all
DMTD typically is all about measuring oscillator stability to ppt (1e-12) or better. The main point is: By mixing the DUT frequency with e.g. a 100Hz (10Hz, 1Hz) offset reference, the errors get multiplied by the ratio of reference to offset frequency (e.g. 100000 for 10Mhz / 100Hz), this way shifting picoseconds into 100's nanoseconds range, which can be easily measured by conventional counters. The TA520 is quite a luxury item here, as its 25ps resolution isn't required at all for these measurements.
The complete solution:
That thing has a major flaw: Gravity is not a force it only appears as such.

The picture just illustrates that there can be something beneath all known phenomena,
whatever their nature. Since we do not know whatever that might be.
So you just invented a new principle.

any good ?
he would trade for a Voltcraft 160 MHz AFG, I have a Peaktech 160 MHz AFG.
Would that be a good trade ?
Seriously dodgy. The title says TDS3052, some of the pictures are of a 3032, but others are a 3034?? And the language on the devices change between German and Russian?? So what is he actually selling? There are no pictures of a 3052.

It seems to be a case of the often claimed bandwith extension by SW hack. Would not risk it.
That still wouldn't explain how it suddenly turned into a 4 channel scope in one of the pictures and then back to a two channel model??

I'm a long-time follower of Sabine's YT channel, I'm aware of that.

yes, exactly.
The game has already been changed. There's already loads of these on the market for quite a while now. Why would another one be needed?

If so please point me to one. I am not talking about Glucose, but Insulin. Have been unable to find a personal Insulin meter. Will gladly buy one if the price is within reason. I do have a personal glucose and ketone meter, but that is not really sufficient.

That's about a
glucose sensor. Glucose ≠ Insulin, one's a simple disaccharide, one's a hormone.
FreeStyle Libre ® heißt das Flash-Glukose-Messsystem, das seit Ende Oktober für erwachsene Diabetiker verfügbar ist und direkt bei Abbott im Online-Shop bestellt werden kann.

I know. But I cannot see the sense in measuring the insuline. All friends of mine with diabetics (type I and II) are only measuring the glucose. None of them is measuring the insuline level. And one of them has a similar sensor system to the one described in the Ärzteblatt above.
Ifni save me... I'm going there.

Been there, done that - long time ago when I could use my eyes without artificial amplification to do such soldering. Last time I had a broken FPC, luckily some chinese seller offered replacement for little money.
Yeah, the FPCs are available cheap,
if you feel like tackling the assache of swapping over four .5mm pitch ribbon sockets, three IR photosensor pairs, and three diodes. 7 little bodge wires feels a treat in comparison, honestly.
You
can get them fully populated for ~US$24 each... but then you have no idea of the quality of the components, you have to play the fleaBay cesspool game, and with two cameras I'm now looking at $75 invested before I buy batteries and chargers...
...or I can spend a couple hours doing the bodge thing and at least see if that's all the little beastie needs before I plonk down real money on parts to fix a decade-old camera.
Really, the math wasn't that hard, especially since it sidesteps the whole border delays/duty/slow boat from China asshole tax.

There is this 3478A on eBay if anyone is looking for one https://www.ebay.co.uk/itm/274949249296
Dammit Specmaster I was hoping to keep that one a secret!
Already on my watch list and finished the day I get paid so...

They are not doing it because they can't, not without sending bloods off to "biochemistry".
Think of "insulin resistance" and the more familiar resistance. I give you a resistor and say measure its value, but you can only use current, you may not measure voltage. Think of glucose levels as voltage and insulin levels as current - they interact through the insulin susceptibility or resistance. You can't find that insulin resistance without measuring both.
