The Stereo Waveform
Oscilloscope enables you to see your Music waveforms for test purposes, for
analysis purposes, or just for entertainment. The Oscilloscope software taps
into the output Digital Audio Data stream to show you graphically what you are hearing
from your system.
The Oscilloscope can be
operated in Auto Trigger Mode, where the trace is updated as fast as possible which is best for test and analysis purposes. The Oscilloscope can also be
operated in Single Trigger Mode where the trace is updated only when manually commanded
to update. The Oscilloscope can also be operated in Music Mode where the settings are optimized for viewing Music.
The Gain can be adjusted so
that very small signals can be displayed as well as very large signals. The
Sweep Rate can be adjusted so that low frequency signals are easily viewed or so
that high frequency signals are easily viewed.
The Oscilloscope can display
waveforms in many trace modes such as Left Plus Right, Left
Minus Right, Left Only, Right Only, Left On Right, and Dual Trace. The
Oscilloscope can operate in Persist Mode where successive traces are not erased
but are drawn on top of each other.
The Oscilloscope Trigger
Level, Trigger Delay, and Trigger Slope are adjustable to provide stable viewing
of almost any waveform. The Oscilloscope can trigger on the left or the right
channel in the Dual Trace modes.
The Oscilloscope has a front
end compensation filter that can be enabled or disabled. The filter has a
characteristic that emphasizes certain frequencies to produce a more interesting
output when viewing music. This compensation should of course be disabled when
The Oscilloscope screen is
fully integrated into the main screen display so that normal Stereo Workstation
activities can continue without interference.
Fortunately, the non-technical
person will not have to know anything about Triggering, Gain, or Sweep Rates
because the default settings of Music Mode are designed to display interesting waveforms for
someone that just wants to watch.
The following image shows a screen shot of a typical Music waveform as shown on the Oscilloscope screen.
The Oscilloscope is set to Auto Trigger using L Plus R Trace Mode where the left channel
is added to the right channel and then displayed. The
Scope is set to trigger on the left channel signal.
