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.

a. The dynamic range specification is the ratio of the channel power to the power in the offset and region
specified. The dynamic range depends on the measurement settings, such as peak power or integrated
power. This specification is derived from other analyzer performance limitations such as third-order
intermodulation, DANL and phase noise. Dynamic range specifications are based on default measure-
ment settings, with detector set to average, and depend on the mixer level. Mixer level is defined to be
the input power minus the input attenuation.
