The Complementary Cumulative Distribution Function shows the probability with which
the output signal will exceed the average power.
The level over the average power is plotted from 0 to 20 dB on the X axis; the average
power (RMS) corresponds to the origin. The probability of exceeding the average power
is plotted between 0.0001% and 100% on the Y axis. The recording depth is 8kSamples.
This signal is picked off at the output of the baseband main module ("Impairment" function
block), i.e. contained in the displayed signal is:
●
impairment of the signal as defined by the user and the addition of noise.
●
Fading of the signal as defined by the user
●
an added external (Baseband Input)
●
an added internal signal (from the second path).
