a
a. The Complementary Cumulative Distribution Function (CCDF) is a reformatting of the histogram of
the power envelope. The width of the amplitude bins used by the histogram is the histogram resolution.
The resolution of the CCDF will be the same as the width of those bins.

a. The dynamic range specification is the ratio of the channel power to the power in the offset specified.
The dynamic range depends on the measurement settings, such as peak power or integrated power.
Dynamic range specifications are based on default measurement settings, with detector set to average,
and depend on the mixer level. Default measurement settings include 30 kHz RBW.
b. This dynamic range specification applies for the optimum mixer level, which is about −16 dBm. Mixer
level is defined to be the average input power minus the input attenuation.
