Math Descriptor Label
When a Math trace is ON, there is a descriptor label on
the display for it, much like for the channels, zooms, and
memories (reference waveforms).

The top line contains information about how the Math trace is defined
(in this case, it’s an FFT of Channel 1).

The 2
nd
line contains vertical scaling information.

The 3
rd
line contains horizontal scaling information.
If the descriptor label is a solid color (as follows), then
the Math trace is ACTIVE, which means that the
Horizontal and Vertical front panel controls are set to
adjust the Math trace, and not any of the channels. In
this case, the scale and position of the Math trace can be changed by
adjusting the horizontal and vertical controls on the front panel.
If the Math trace is not ACTIVE, and you wish to make it ACTIVE, simply
touch the descriptor label once and it becomes active and the Math dialog
opens.
Zooming Math
Math traces have zoom capability built in, so it is easy to change the scale
and position of the Math trace, as required. Zoom the channel as follows:
1. Touch the descriptor label to make it
active.
2. Then, use the front panel horizontal
and vertical controls to adjust
position and scale. The operation of
the knobs feels natural. Use the
following table as a guide.
NOTE: When Math trace is active, no
channel buttons are lit. This indicates that
the Math trace may be currently active.
