Hi Rob,
I know this sheet - Except the mentioned probes before, the maximum bandwith of the others are 300Mhz.
I would like to have at least 350Mhz probes for my (now)350(500)Mhz scope.
But when there are no alternatives, I´ll go for the 300Mhz versions from siglent.
(Already looked around, there are some "cheap" so claimed 500Mhz probes on the market, but they´re looking suspicious to me)
