Fig. 4-18 Display of the complementary cumulative distribution function (CCDF)
Alternate to the histogram display of the APD the Complementary C
umulative Distribution 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
Note: During an active statistic measurement the functions FULL SCREEN, SPLIT SCREEN and
selection of the active diagram via SCREEN A / SCREEN B are disabled.
