RBW
Defines the resolution bandwidth (RBW) of the spectrum. The resolution bandwidth
defines the minimum frequency separation at which the individual components of a
spectrum can be distinguished. Small values result in high precision, as the distance
between two distinguishable frequencies is small. Higher values decrease the preci-
sion, but increase measurement speed.
The RBW can be determined automatically by the R&S
EVSG1000, or manually.
AUTO mode
The RBW is determined automatically according to the sweep time
and frequency range.
