Oscilloscope Menu - Omnia .9 Installation & User Manual

FM MENU DISPLAY SETTINGS

Oscilloscope Menu

The Oscilloscope menu allows you to monitor a very wide variety of input and output points from various stages of
Omnia.9's processing sections on the built-in oscilloscope. In the above example, the single Display 1 is selected, with the
Instrumentation button engaged, as well as the Oscilloscope button.
The Delay control works the same here as it does previous and subsequent 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. However, 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.
