DISPLAY AND METER OPTIONS
♦
The
Multiband
category allows the oscilloscope to display the outputs of each of Omnia.7’s multiband
AGC’s. The total number of available bands is dependent upon the number of bands used in the current
preset.
¸
The output of each individual band of the multiband AGC can be selected by choosing one of the
Solo
Band
patch points.
¸
The
Post Multiband
patch point is the summed output of all bands including all processing preceding
the multiband AGC’s.
♦
The
Monitor Output
category allows the
Speaker Source
and
Headphone Source
audio to be displayed
along with the
Speaker Output
and
Headphone Output
audio.
When the oscilloscope is selected as the current type of instrumentation, controls for adjusting its display are
provided in the Display Options menu. It may be necessary to scroll down to view these controls.
♦
The
Delay
control works the same here as it does in other display sections.
♦
The
Oversampling
control enables or disables the oscilloscope’s 4x oversampling function. Without
oversampling, some peaks may pass through without being displayed, giving an inaccurate view of the
signal. This is most critical when monitoring the MPX Output or the L/R Pre-emphasis Output. Howev-
er, since oversampling consumes more CPU resources, it is turned off by default.
♦
The
Phosphor Persistence
control adjusts how long latent images remain on the screen. A setting of 0
provides no image delay at all and offers the greatest amount of visual detail for the current information
on the scope.
Higher settings allow images of signal that has already passed through the scope to remain on the screen
for progressively longer periods of time. Setting this control all the way to the right keeps the image from
fading at all, useful for catching peaks.
♦
The
Gain
control adjusts the Y scale of the oscilloscope and moves the grid relative to the signal.
♦
The
Lines
control adjusts the offset of the reference lines as measured in dB.
♦
The
Zoom
control allows you to choose between a 1x, 2x, and 4x view of the X scale, similar to setting the
sweep time of a traditional oscilloscope.
