Yes, they are saying that they don't spec for logic clock frequencies higher than 200 MHz but you need at least double this as the sampling rate; again, I am pretty sure that the MSO5000 samples the LA pins at 1 GHz, that's why there's a 1 nS jitter when you're looking at 200 MHz waveforms.

Thank you for your excellent work - very appreciated ^-^
Are we now looking into two deterrent designs and two deferent tests ? or are you working together on this project ?

The 2 projects are both LA probe leads that plug into the Rigol MSO5000 series scopes but they are completely different designs.
Mine came first. I have looked at S.Petrukhin's design and offered him my advice and what I believe is constructive criticism. I am not running a business (at least not one selling LA probe PCBs) and I don't feel like I'm in competition here.
[EDIT] I now realize that you were asking about Hydrabus' design vs S.Petrukhin's. I have a completely unrelated design here.

I quickly made a simple version myself which is easy to repeat by ordering PCB and accessories in a couple of clicks.. I was really helped by the guys in this forum, who studied and gave information about the standard device. @Gandalf_Sr especially helped-he found errors and suggested them to me. @hydrabus upgraded the board and made an independent version.

Good evening,
I just bought a rigol mso5000.
I came across this blog.
I went to the Chinese site:
https://easyeda.com/f33net/digital-probe-rigol-mso5000
I saw an opportunity to purchase components.
But I don't see an opportunity to buy the board.
I know it's a simple question but can you help me?

Hi!
I answered you on that site: you need to open the PCB in the Editor (see this name button) and select [Fabrication / PCB Fabrication file (PCB)] from the menu there. Then choose when ordering 5 pieces - they will cost $2 plus shipping.
