Version 09.00, December 2008 R&S ® FSL Spectrum Analyzer 33
Measurement parameters
predefined bands preset combinations of sampling rate (F
s
)
and nominal channel bandwidth (BW) in
line with standard
Frequency band
unspecified standard-compliant or user-defined F
s
/BW
ratios
Sampling rate (F

),
channel bandwidth (BW)
If one of the parameters is set, the other is
automatically set as required for the
selected standard. The frequency band
setting is taken into account.
