Each Radio Standard has the preset parameter set for the measurement.
When a standard is selected, the default value of the measurement parameters are
overwritten by those preset values.
When the standard is NONE, or the standard does not specify the firm RBW
requirement, then the table displays “auto”, and the following definition is used to
compute the proper RBW setting:
1.
Compute the guard-band = [Offset Freq A] - 0.5*([Chan Integ BW] + [Ref BW])
2.
Divide by 4.5. Call the result GuardbandGoalRBW
