LCR Cal Test PCB

[KungFuJosh]

I want to reproduce this as soon as possible.

You'll hopefully receive your PCB next week or the week after. Mike should have his (and my tested board) on Saturday.

Here's the results comparing my ST2832 and ST42 on V5 of the test board. Most tests were matched at 360mVrms (ST42 tested at about 358mVrms).

The DC bias values are based on 1kHz or 10kHz frequency for AC. It matters for some reason. 🤷

I think I did step DF test at 1Vrms. I forget, that was way back to yesterday.

Thanks,
Josh

Use your SDM3065X to measure the Thermisistor (2 wire), it should yield ~78F or ~25.6C.

Oops. A little late now, it's on the way to you. I'll try it out next time. 😉

No problem, we'll measure it when the PCB arrives!!

It's not ready yet, but Mouser delivered today and everything has arrived.
I ordered everything from your parts list 2 times, you never know how stupid you can be when soldering.

I always get at least 3 for the same reason...except even stupider: sometimes I don't pay enough attention when I test SMT stuff, and the parts might become airborne. 🤣 ...only lost 2 or 3 items on the last board I made.
