The core of the main window is the two diagram panes that will display the
results of your measurements. Each of them may show different measurement
result views. When you have started OPERA™ for the first time, the diagrams
display an incidentally chosen diagram type. Otherwise, the system will recall
the last diagram type you have displayed before you closed OPERA™.
On the right side of each diagram information about the measurement settings
is shown. The content of the display varies depending on the algorithm you
have chosen.
At the bottom of the main window you will find the slider which is used to
move the cursor in the time domain of a diagram. At the moment the slider is
not active since no measurement has been performed yet. After having
performed a measurement, drag the slider with the mouse and scroll through
the signal. Other options to move the slider are to click into the grey area
besides it, or to click once onto the slider to give it the input focus and then
move it with the cursor left and cursor right keys.
The meaning and operation of all menus will be explained in detail later on
while presently focussing on those items that are required to perform a first
measurement. To that purpose the measurement algorithm "
available on all OPERA™ Systems will be used. "Scope" does nothing else but
performing data acquisition, signal preprocessing and displaying the time
signals like an oscilloscope.

To select a measurement algorithm, select the menu Measurement|Algorithm
Parameters... After doing so a dialog like the one shown in Figure 4.25 will
appear. This dialog will show all algorithms currently installed on your OPERA™
system.
