Screen feels a bit small once you have the MSO on
Mso probe has an acvtive head and 0.1" pin header, and they supply single wire probe leads, not paired with gnd so could have inductance issues.
Us guy also thought it nuts thay they did a 2ch version.
Has HDMI out, which for some reason has option to diwnscale to VGA and 720xsomething-is there any hdmi device that would need that?
sorry, wrong thread - was talking about the Rigol!
