From which year does the LeCroy X-Stream patent date?
I don't know, there are various patents (not just a single one) but some must be from the late '90s or so as the first X-Stream scopes came out in 2001.
I found a patent from Tektronix that claims substantial improvements over the Agilent MegaZoom technology and the LeCroy X-Stream technology.
Well, Tek can claims a lot, what matters is what they bring to market.
Imagine that the technology in this patent would actually outperform LeCroy.
Yeah, don't hold your breath. Tek is pretty much the bottom end of all big brands, and has been for a very long time. They pretty much stopped being innovative when analog scopes became a thing of yesteryear, and as part of the Danaher family that is unlikely to change anytime soon.
Some people will hate that finding, as it's their popular brand =)
I don't care about brands, I'll buy whatever does the job best. Sometimes that's Keysight, sometimes that's LeCroy, or R&S, or something else.
I don't get the fanboi-ism for a specific brand. That's just silly.
One day we might even learn about a new patent from Rigol, that beats all previous technologies.
That would really make my day! =)
Well, I guess Siglent could try to patent its "sales price enhancing technique", but then Rigol can claim prior art. So it's not as if they weren't innovative
