Good point. I used to have an old cro with one of those,
now I've got one of those new fangled Tektronics digital
ones. It's got a lot of useful functions (voltage & freq
measurements on the screen etc) but that's one thing it
doesn't have. You wouldn't happen to have a circuit to
build the external version, would you?

TIA :))
