Now that I have both a differential probe and a current probe from Micsig, I'm looking about the Power Analysis features of scopes and am wondering why Deskew Fixtures are expensive, as they look quite simple in design. As I'm a Siglent user I've looked for their fixture and saw on the forum that in order to calibrate those Micsig probes I have, the PCB has to be cut/adapted, and even so I believe it's overpriced.
After looking around, I realized all A-brands seem to sell "raw PCB" fixture devices, which look cheap but are very expensive (oh, by the way, why are all those devices sold as a simple PCB without any case? Doesn't look professional imho, but there must be a reason I don't really catch.
On Aliexpress I also researched for cheaper "clones", supposing some manufacturers there may have the idea of designing cheap ones but I didn't find any. That's puzzling for me too, why aren't any chinese manufacturer selling that? (after all they design and sell a ton of crap boards, this one shouldn't be difficult to make either).
I remember that there was at least one company in the Netherlands or Belgium that had created a homemade fixture but my memory is deficient and I can't recall the name of the website, I just think it was a long time ago (when I didn't guess what it was meant for) and they stopped selling it. Oh, it's probably Ashlabs, my memory came back... but they seem not to sell the fixture any more
