If it's on the back then it's more likely a Z-axis input
rather than another trace. This input allows you to modulate
the brightness of the trace (it's called the Z-axis because
it's like a third dimension - the "in and out" direction).
It allows you you do some interesting tricks (like turning
your scope into a tiny black-and-green TV if you like), but
generally isn't that much use.
