This topic describes the CCDF functionality using the graph in the Carrier view. Clicking under the tree view to display the CCDF graph.
The CCDF graph displays the probability (in percentage) of the generated waveform's calculated peak-to-average power ratio (measured in dB) meeting or exceeding a certain 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.
Any 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.
The CCDF and Waveform graphs are minimized in the Carrier node's initial view. To view the graphs, click and drag the border above the CCDF and Waveform graphs.
Select in the , shown as follows.
The CCDF Curve is as follows.

The CCDF Curve is as follows.
Each time you adjust parameters and generate a waveform, a plot is added to the graph. The graph retains your three most recent plots (in shades of gray), allowing you to make comparisons of waveform characteristics.
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.
