Persistence: This selection option is used to determine how long a data point (pixel) remains on
the display. The range of Persistence is 0% to Infinite. The default selection is 0%.
Attack: This selection option is the initial intensity that the data point (pixel) appears in the
display. The range of Attack is 1% to Maximum. The default selection is 50%.
Automatic Gain Control: This selection option is used to keep the display visible from very small
levels to very high levels.
Plot: This selection option is used to select one of two types of Lissajous displays. The
soundstage selection displays a Lissajous that is rotated so that the in-phase signals appear on
the vertical axis and out of phase signals appear on the horizontal axis. X-Y displays a Lissajous
with the left channel mapped to the vertical axis, and the right channel mapped to the
horizontal axis.
Configure Phase Bar(s): Phase bars are used to monitor the instantaneous phase relationship
between two channels of audio. On a vertical audio display the "+" marking indicates a phase
difference of 0°, and the "-" marking indicates a phase difference of 180°. A properly phased stereo
pair produces a phase pointer that moves within the green zone, whereas a reversed channel
produces a pointer that moves within the red zone.
Polarity: This selection option is used to set the phase bar polarity to Normal or Reverse. The
default selection is Normal.
Damping: The effect of higher damping in a phase meter is to show an averaged rather than a
peak value of phase. This selection option is used to set the phase bar damping to Fast, 1 to 10,
or Slow. The default selection is 5.
AES Validity Bit: The AES Validity Bit is used to detect pulse code modulation (PCM) audio or non
PCM audio. Non-PCM audio can include Dolby or other digital data.
