> Trace C Operations
A -> C: Copies the contents of Trace A into Trace C. Doing so overwrites the
previous contents of Trace C.
B <--> C: Swaps the contents of Traces B and C.
Max Hold -> C: Shows the cumulative maximum value of each display point
over many trace sweeps.
Min Hold -> C: Shows the cumulative minimum value of each display point
over many trace sweeps.
A - B -> C: Subtracts the value of trace B from trace A and places the results
in Trace C. This function is very useful for observing the changes in values of
live Trace A compared to a trace stored in Trace B.
When trace math is active, a relative scale shows on the right side of the
graph, and is associated to Trace C. This allows the user to optimize the
display of Trace C without affecting the display of Traces A and B.

Relative Ref: Sets the value applied to the top graticule for the relative scale
that appears on the right side of the graph when trace math is active. Change
this value by using the rotary knob, up or down arrows, or entering the value
on the numeric keypad and pressing the dB submenu key or the
Enter key.
This entry is valid only when trace math is active
