The phase display plots audio input signals in a Lissajous phase display. This
display may be configured to show the signals in either soundstage (the default)
or X-Y (oscilloscope) format. The display also provides a bar graph of left
channel, right channel, and left plus right channel sound levels. The scales of the
bar graph display may be configured for Nordic PPM or DIN 45406 dB, or VU
units. For information on configuring the phase display, see Configuring the
Audio Option beginning on page 1–1.
