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.
