Audio Display Pop-Up
Menu
WFM5200 Waveform Monitor User Manual
The Audio pop-up menu enables you to select the audio input source and specify
whether a phase display or a surround-sound displays appears in a subtile to the
right of the level meter display.
To select the source for the Audio display, select Audio Input in the menu and
set a source. The number of available sources depends on which audio option is
installed. Choosing any given input will make that audio the monitored signal
regardless of which video input is active. Alternatively, choose Follows Video
to enable the mapping that allows changing the audio source as the video input
selection is changed.
NOTE.
Use the CONFIG menu to select the mapping of input to bar, the meter
type, and the Follows Video mapping of audio to video.
Headphone input maps audio pairs to the front panel headphone jack.
Analog Out Atten is used to adjust the levels to the rear panel analog outputs.
To add a 2-channel phase display to the audio tile, set Aux Display to Phase
Display in the Audio pop-up menu. A phase display is also called a "Lissajous"
display.
To choose the plot style of the Phase Display, select between the following two
entries in the pop-up menu:
Sound Stage has axes rotated at a 45 degrees.
X-Y has axes that are horizontal and vertical.
To choose the pair of inputs that is displayed in the phase display, select Phase
Pair and set a value. You can also select Custom, and then specify individual
channels for the input pair, using the Phase Channel A and Phase Channel B
entries.
To define when audio channel pairs are considered out of phase and the Audio
Phase alarm occurs, you should set the following two parameters:
Phase Err Corr: Defines the percentage of correlation error that must occur
before the Audio Phase alarm is triggered.
Phase Err Duration: Defines the duration of time for which the error must
occur before the Audio Phase alarm is triggered.
