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 10.0 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.
