Bandwidth
Resolution Bandwidth defines the resolution bandwidth for the Spectrum meas-
urement. The resolution bandwidth is identical with the RBW set with the Analyzer
Settings softkey.
The nominal resolution bandwidth is the 3-dB bandwidth of the measurement filter.
From a list discrete bandwidths between 10 Hz and 1 MHz can be selected. The
frequencies in the list are given by 1x10
n
Hz, 2x10
n
Hz, 3x10
n
Hz, 5x10
n
Hz where
n=1 to 5. In addition the two values 1 MHz and Auto can be selected.
With the Auto setting the resolution bandwidth is automatically adapted to
bandwidth = span/50
(if this value is inside the allowed range).
Resolution bandwidths for the analyzer and the Power measurement can be set
independently (see also p.SEITENREFFORMATVERBINDEN 4.40).
