I planned to use JLC, but the verification girl insisted it's a "5-board" one and the price was almost 100 USD. I failed to correct her that it was "2 designs only" board. Finally I had to change to another vendor who does not understand impedance part.
Anyway, the board is being shipped to me now. And I also purchased 2 LMH7324 directly from TI (FedEx from Texas) which is expensive but should be genuine.
Hoping for the best result.

Got them. Although the PCB manufacturing is really not good.
ebclr:
Do you have any spare set of boards to sell/share
whowe:
I would like to share them, but I'm in China. Oversea shipping is costy.
And what's worse, is that I might have made a mess. It's not working, yet.
Could be bad PCB manuafacturing, could be bad soldering, or maybe partially wired USB cable. I don't know yet.
Will update later, mmm, when I figure out what's wrong there.

:-DD the various silkscreen jokes on that PCB are great!

Check this problem.
Without connecting any satellite adapters. Some channels are high, some are low. Especially the D6, it has a 32MHz (not accurate) pulse. Don't know where it picks up from.
As a reference, a put a 10MHz sine ware on Analog Channel 1. See the screenshot.
