What's inside a $13K Agilent Source Measure Unit capable of 15fA and 100nV resolution?
Plus triaxial cables, and low current measurement connection.

I think it's awesome that they'll send gear that they have very little chance of getting extra sales of, due to low demand and price, just because. I am sure it'll increase sales of lower priced products, I know ultimately it's all a marketing decision, but a good one in my not-so-humble ;-)

​@@TheChipmunk2008 This channel actually is VERY close to the target group. I think Dave once said that a quite significant amount of his viewers are professional engineers. And those people can easily become involved in the decision process of buying such equipment .. and lending out such a unit is cheaper than a magazine advert or something. Besides of that, they were probably using one of the demo units they lend out for evaluation to potential customers anyway (and the last one forgot that LED in there..) ..

That's why I love watching and listening to you Dave in your videos, You are clearly very knowledgeable in the world of Electronics but some of your phrases kills me. When you were talking about the TI OPA 1611 opamp (30:32) and saying you could 'Fart half way across the solar system and generate less distortion' while LMAO funny, pretty much tells you without any compromise the spec of that poor sucker. By the way, you must be doing something right for HP (They are still HP in my book, we mainly used HP at GEC in the 80s) to loan you not 1 but 2, $13K test units.... (Just wiping the drool off my chin there).. Thumbs up for everything Dave.... Oh by the way, the other video you made which featured Sagan opening your 'Mail on Monday' you revealed he was 3?... that meant he wasn't even a glint in the proverbial eye when you started your uploads.....boy has he got some catching up to do......

It's all simple business logic. It's most likely one of their demo units anyway, he is knowledgeable (maybe a little clumsy at times) so say there is a 5% (tops) chance of him seriously damaging it. Say it has an actual book value of $5000 (they pay the production/development cost, not the selling price) .. 5% of this would be $250. Let it be 500-1000 with all the shipping, handling, management ... ... you won't get an 1 hour advert video, which also targets EXACTLY the people you want to drool over it (MANY professionals with the power to buy something like that watch his channel) for this money anywhere else.

You mentioned the triax cables, and how shielded they are, and how expensive they are, but not that they're made out of special low triboelectric materials? And how if you're doing low current measurements, you must wait after moving the cables to get accurate measurements? In my experience, even tapping the desk that the cables are sitting on can be seen in low current measurements in the fA range. Pretty touchy stuff - literally!

I'd love to see how you use one of these things to characterize components. Say a complimentary pair of PNP/NPN transistors (PNP is harder to get good performance out of than NPN, can we see the difference?), a LED or even better a laser diode (how do they differ), and a MOSFET (maybe again a complimentary pair)? Given limited time, what would be most interesting?

Another problem with putting vias in pads like that is that the solder balls that you get on the opposite side prevents a tight fit with the solder paste stencil causing to much paste being applied and in turn causing solder bridges. This of course only applies to double sided mount boards.

Way late to the game here, but one of the other main advantages and purposes of the triax probing system is that you can have your circuit that is being tested to be at a significantly different base (ground) reference than the test gear. E.g. the circuit under test can have its ground potential floating at several hundred volts different than the Agilent B2912 and yet be able to still allow for femto-amp current measurements between hi and lo, since their chassis grounds are independent. Just had to add that tidbit of info.

The triax is used to eliminate leakage current more so than noise. Typical coax is 100MOhm between conductor and shield, so even with just 1V, leakage current is 1nA, making any attempt to measure below this useless.

I figure they reason they have to re-caliberate it is that when taking it apart you have to break the seal that guarantees the calibration to be correct and for them to be able to replace the seal they have to be absolutely certain that its 100% up to the right calibration specs, even though they know you won't go messing with everything, they just have to know for absolute certainty that nothing accidentally changed. The people that use anything that is calibrated like that place complete trust in it. I'd just take their insistence on re-caliberating it as evidence that they just take the trust their customers put in them very seriously and set high standards on just being sure.
