Fig. 4.13 Display of the complementary cumulative distribution function (CCDF)
Alternate to the histogram display of the APD the Complementary Cumulative Distri-
bution Function (CCDF) can be displayed. It shows the probability of an amplitude
exceeding a specific value.
For the APD function the x-axis is scaled in absolute values in dBm, whereas for the
CCDF function the x-axis is scaled relative to the MEAN POWER measured.
Definitions:
Crest factor = peak voltage to rms
CCDF = complementary cumulative distribution function
During an active statistic measurement, the functions FULL SCREEN,
SPLIT SCREEN and selection of the active diagram via the SCREEN A / SCREEN
B hotkeys are disabled.
