2. To control the mode of representation, select it in the ​Mode combo box.
The "Viewport" bar indicates the following information depending on the selected
mode of representation:
"Mode" "Viewport" Yellow Bar White Bar
"i(t)/q(t)"
"r(t)/q(t)"

Note: There is no limitation to the length of the waveforms. Long waveform streams are
divided in packets of an displayable size and are then displayed packet-wise.
In the "Viewport" group box, the following fields are displayed:
"Min"
"Max"
"Range"
"Unit"
Begin of scope.
End of scope.
Delta between values in the "Min" and in the "Max" fields.
Tip: It also possible to set the "Min" value and the "Range" value, the
"Max" value will be adjusted automatically.
Units of the "Min", "Max", and "Range" values. If the unit is changed,
the values contained in the "Min", "Max", and "Range" fields will be
converted. Subsequently, the values in the new unit can be changed.
Mode
Controls the mode of representation.

Displays the actual waveform over time in two windows: the top one for
inphase, the bottom one for quadrature samples.
Displays the actual waveform over time in two windows: the top one for
amplitude, the bottom one for phase values.
The samples are depicted in the complex plane, transitions displayed
as vectors.
Complementary Cumulative Density Function
Spectrum (magnitude over frequency) derived from a Fast Fourier
Transform of the signal.
All sample points displayed in the complex plane.
