specified 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. See "Specifications" for the available power sweep
range.
The output power of the tracking generator is swept according to the
sweep rate of the spectrum 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. Key Access:

Man tracking generator's switching attenuator. The HP ESA-L1500A can be
manually adjusted from 0 to 60 dB in 10 dB steps. When auto-coupled,
the attenuation function automatically adjusts the attenuator to yield
the source amplitude level specified by the
function. Set
(decoupled) for power sweeps greater than 10 dB.
