Hi all,
In this book (1986 edition) I'm reading on scopes, in the section on manufacturer's claims for bandwidth, it states: "The rated bandwidth of the highest quality oscilloscopes is quoted as that frequency at which the full screen response has fallen by 3db. Other manufacturers quote the -3db figure for half screen height deflection, whilst one North American manufacturer who shall remain nameless quotes the bandwidth at the -6db point for quarter screen height deflection. Let the buyer beware."
So who's this nameless and shameless scope maker? Anyone know?
