Complementary Cumulative Distribution Function (CCDF)
The CCDF measurement displays the CCDF and the Crest factor. The CCDF shows
distribution of the signal amplitudes. For the measurement, a signal section of settable length is
recorded continuously in a zero span. The measurement is useful to determine errors of linear
amplifiers.
The Crest factor is defined as the difference of the peak power and the mean power.
Beneath the measurement screen a table containing the number of included samples, mean
and peak power and the Crest factor is displayed.
The default settings of the CCDF measurement are listed in the table below.

In a transition from the base unit to the CDMA2000 BTS Analyzer option, external trigger sources are
preserved, all other trigger sources are switched to the Free Run trigger mode. Additional trigger
settings are preserved.
