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.
Key Access:
Allows you to select between automatic and manual adjustment of the

tracking generator's output attenuator. The Agilent E7401A can be

manually adjusted from 0 to 60 dB in 10 dB steps. All other Agilent
EMC 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 specified by the
On Off
for power sweeps greater than 10 dB.
Key Access:
When the source attenuation is set manually, the actual source

amplitude may be greater than the amplitude indicated by the source
amplitude. With source attenuation set to manual, source amplitude is
permitted to be set to values beyond output levels to accommodate the
full range of the analyzer capabilities. As a result, exercise caution
when connecting a power-level sensitive device to the tracking
