5.10 Meas Setup
(Complementary Cumulative Distribution Function—CCDF)
When Power Stat CCDF has been selected in the Measure menu of the Spectrum Analysis
mode, this key displays the appropriate measurement setup menu for the complementary
cumulative distribution function (CCDF).
Power Complementary cumulative distribution function (CCDF) curves characterize the
higher-level power of the signal. It provides the distribution of peak-to-average power
ratios versus probability. A CCDF curve is defined by how much time the waveform spends
at or above the specified power level. The percent of time the signal spends at or above this
level defines the probability for that particular power level.
