Power Statistics CCDF
Minimum power at RF Input –50 dBm (nominal)
Histogram Resolution

a
a. The Complementary Cumulative Distribution Function (CCDF) is a reformatting of a 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 accuracy of the Adjacent Channel Power Ratio will depend on the mixer drive level and whether
the distortion products from the analyzer are coherent with those in the UUT. These specifications
apply even in the worst case condition of coherent analyzer and UUT distortion products. For ACPR
levels other than those in this specifications table, the optimum mixer drive level for accuracy is
approximately –37 dBm – (ACPR/3), where the ACPR is given in (negative) decibels.

b. ACPR accuracy for this case is warranted when the input attenuator is set to give an average mixer
level of –20 dBm.
