content: I needed to work out what an I2C bus was doing wrong today...LeCroy didn't even bother to put I2C decode on it. The noise is because I'm using the passive X10 probes and my ground loop is tangled up in the VFD on another device.In my defence it was the only scope not in use and it was already on a trolley.

content: The name of my four pound hammer is "Gentle Persuasion".Just remember there is no limit as to how soft you can hit something with a hammer. I have a machinist's hammer though that I have had to reface as the steel it was made from was starting to flow and mushroom from use.

content: Huh. Looks like it's available on a wide range of scopes (presumably all with similar firmware). OK, a better question would be, is there any niche in EE where such a combination would actually be used? I can't think of any.

content: Not that I can think of, but it does make the scope more versatile, one for everything I suppose.Besides, they can then charge you for it, even if you never use it.

content: Quote from: c4757p on November 15, 2013, 06:53:01 pmMe neither. That's why it is a big paradox: people expect that the biggest  offers the most features and/or performance, so the scope should have the option/feature.. but you shouldn't really be using it, if you know what I mean

content: I didn't know I2C was available, ours only has 8b10b installed. When I'm not being an idiot it gets used for PCIe, SAS and FC. If we're looking for decode we tend to use an Analyser/Jammer though.
