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
−18 dBm. Mixer level is defined to be the average input power minus the input attenuation.
c. The sensitivity is specified with 0 dB input attenuation. It represents the noise limitations of
the analyzer. It is tested without an input signal. The sensitivity at this offset is specified in the
default 30 kHz RBW, at a center frequency of 2 GHz.
d. The relative accuracy is a measure of the ratio of the power at the offset to the main channel
power. It applies for spectrum emission levels in the offsets that are well above the dynamic
range limitation.
e. The absolute accuracy of SEM measurement is the same as the absolute accuracy of the spec-
trum analyzer. See “Absolute Amplitude Accuracy” on page 34 for more information. The
numbers shown are for 0 - 3.6 GHz, with attenuation set to 10 dB.
