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.

Power vs. Time
Minimum power at RF input −50 dBm (nominal)
Absolute power accuracy
a
a. Absolute power accuracy includes all error sources for in-band signals except mismatch errors and
repeatability due to incomplete averaging. It applies when the mixer level is high enough that measure-
ment floor contribution is negligible.
± 0.30 dB (nominal)
Measurement floor −84.8 dBm (nominal)
Relative power accuracy
b
b. The relative accuracy is the ratio of the accuracy of amplitude measurements of two different transmit-
ter power levels. This specification is equivalent to the difference between two points on the scale fidel-
ity curve shown in the MXA Specifications Guide. Because the error sources of scale fidelity are
almost all monotonic with input level, the relative error between two levels is nearly (within 0.10 dB)
identical to the “error relative to -35 dBm” specified in the Guide.
± 0.16 dB (nominal)
