Kinda pricey....is it really worth 60 Euro to get a copy?
I am working with them since more than 30 years and they were always a good help to me.
So, I think, yes. Not really cheap I admit, but imo worth it's price.
Received my second 3478A yesterday. Was really pleased to find it's readings are dead on with my existing 3478A. Was a great deal at $80 shipped.
Nice catches, you'd be lucky to snare one of those here in the UK for less then £200 shipped and I doubt that they would be in as a good a condition that yours are.
Yes they look great and amazing that they agree to the last digit!

Which actually means they don't agree, because there would be a voltage drop across that jumper cable. Do they still agree if the voltage source goes to the bottom meter first?

Given the fairly well matched input impedances of 10Meg each likely voltage drop across the connectors and test cables at <0.5 microamp would be???

I doubt with the little current drawn by the meter and cable gauge it would be visible.

Yeah, I was just being a smart arse. You'd need more digits before a difference would show up.

If that "T1" is a transformer, the audiophools will pay $100s for it.
Look it up in Ebay: "Western Electric Vintage Electrical Transformers"
USB>Serial Interface for Maynuo 9710 electronic load, works well - photo shows battery testing run.

Engineer brand, great quality.
Designed myself a T-Shirt and ordered it:
Yeah, I need new t-shirts, this one probably sums me up nicely

really nice crisp and clear picture.
now I have to buy the polariser that fits the led lights and sensor.

Do you know the diameter of the threads in the camera (assuming C-mount)?
I ask, as there's a stable supply of Japanese made polarized filters on eBay for certain sizes. 38mm fits Amscope and similar brands for example (used to attach Barlow lenses and filters beneath the objectives on binocular and trinocular models).
I bought a DSLogic logic analyzer thinking it would be usb3.0 because it uses usb-c. But nope, it's actually usb2.0 ...
At least I bought the version with 256mb sram, so it should still be decently usable, just won't be using streaming mode much I guess.
EDIT: if you want to use dslogic plus with sigrok, you need the latest git version of sigrok and the firmware files here:

I will use a simplier way :

I have received my MC6845 chip for the fully static zero contention PC/XT clone system. Now I need to save up for the CY7C006 dual port SRAM as VRAM.
Original Thaler Corp VRE305 Voltage reference. I bought it from a seller in Israel for $35 shipping included. This is opposed to $75 for the new APEX VRE305 from Digikey.
My APEX chip is drifting well out of specification...about +100uV since Jan 2nd of this year. Previously the IC had been in an aging fixture for 5 months. During that 5 months it also drifted up...roughly +300uV. The specification is 6ppm per 1000 hours...it's pretty close to 1000hrs from Jan2 to now and 6ppm is 30uV. A factor of 3 high. 5 months would be 3600 hours or 22ppm or 110uV...again about a factor of three high. This is actually my 2nd APEX VRE305. The first one was replaced by APEX because its output voltage was a factor of 2 out of specification from the get-go. APEX was responsive to my complaint and sent the replacement FedEx to my home in Philippines. They only required that I mail them the old chip for testing.
I have heard that the original Thalar chips met their specifications, so I will test this one for a few months and we shall see what happens.
