Rescale Memory or Math Function Traces
Unlike channel traces, memory (M1 - M4) or math function (F1 -F2) traces can be rescaled directly
without having to create a separate zoom trace. The same set of controls used to rescale zoom traces
appear on the Zoom right-hand dialog, or on one of the trace setup dialogs. This applies to any trace that
is created as a math function (Fx) trace, including those that are generated through analysis options.
You can, however, create a separate zoom trace from a memory or function trace by drawing a selection
box around a portion of the waveform. In this case, you choose one of the zoom locations in which to draw
the trace, Z1-Z4, but the source trace remains at the original scale.
