X and Y Input Channels
The X and Y channels can be selected using the input channel selection menus, which are accessible from the XY Scope's toolbar.
Scope Options
Mid/Side Mode
The Mid/Side Mode option can be useful for analyzing stereo audio signals and systems (i.e.
when the X and Y inputs represent the left and right stereo channels, respectively).
In Mid/Side Mode, a monaural signal will create a vertical line in the scope. Differences
in the two input channels (i.e. stereo separation) will cause the scope's trace to deviate
from that central, vertical line.
In Mid/Side Mode, the X channel is calculated as the difference between the X and Y
(or Left and Right) input signals and the Y channel is calculated as the sum of the two. In
both cases, the result is divided by two.
X = (X-Y)/2
Y = (X+Y)/2
