frequency range when power sweep is on. (To do a power sweep at a
fixed frequency, set the analyzer to zero span at the desired frequency.)
The available power-sweep range is a function of the source attenuator
setting. For your instrument's available power sweep range refer to the
appropriate Specifications Guide for your analyzer.
The output power of the tracking generator is swept according to the
sweep rate of the analyzer. The output power is always swept from the
source power setting to a higher power setting (negative source power
sweep values are not allowed).
Power-sweep measurements are particularly useful in making gain
compression measurements or output power versus frequency
measurements.
When using the power sweep functionality, the actual source amplitude
CAUTION
will be greater than the source amplitude indicated. The source
amplitude value is the starting amplitude for a power sweep, so the
ending amplitude for a power sweep will be higher then the displayed
value. As a result, exercise caution when connecting a power-level
sensitive device to the tracking generator output.

E4411B can be manually adjusted from 0 to 60 dB in 10 dB steps. All
other Agilent ESA analyzers can be manually adjusted from 0 to 56 dB
in 8 dB steps. When auto-coupled, the attenuation function
automatically adjusts the attenuator to yield the source amplitude level
