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 the specifications chapter in the calibration
guide for the available power sweep range.
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.
