APD Statistics
Amplitude Probability Distribution Statistics – Evaluates pulses statistically. Measurement done in zero
span, at the specified center frequency, with a specific APD dB resolution bandwidth.
– CCDF
Complementary Cumulative Density Function – The probability of the signal power being above a certain
level generated from the APD statistics' histogram results.
– Histogram
Results of the APD statistics measurement and the power levels detected over the APD specified dwell
time used to generate a CCDF results.
