Click or in the 
tree view.
The graph view is located at the bottom of the Waveform Setup and Carrier
nodes. For multiple antenna configurations, a tab for each antenna port
is displayed above the graph view. Click the tab for the antenna port
for which you want to view a CCDF graph. Click the CCDF tab to display
the CCDF graph.
The CCDF, Waveform, and Power Envelope graphs are minimized
in the initial view of the Waveform Setup node and the Carrier node. To
view the graphs, click and drag the border
above the CCDF, Waveform, and Power Envelope graphs.
The CCDF graph displays the probability (in percentage) that the generated waveform's calculated peak-to-average power ratio (measured in dB) is greater than or equal to a specified level. The table to the left of the CCDF plot displays the calculated peak-to-average values for the current waveform. For additional information, see Understanding CCDF Curves.
Click 
or 
from the main tool bar to generate an I/Q waveform and plot the CCDF graph
using the current channel configuration. Changes to the channel configuration
setup do not appear on the graph until you generate the waveform. The
status bar at the bottom of the screen shows waveform generation progress.
Use the buttons shown below to plot the Gaussian data, reference data, and generated waveform data to the CCDF graph. The graph's initial state shows only the Gaussian curve (blue) until you generate a waveform.
Click the button to toggle the Gaussian noise curve (blue) on or off.
Click the button to toggle the reference curve (red) on or off.
Click the button to set the current waveform curve as the reference curve.
