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.
