:SENSe:FREQuency:SPAN
Description
This command gets or sets the frequency span of a sweep. If the frequency span is altered, the start frequency the stop frequency and the center frequency are changed accordingly.
If the specified parameter is out of the allowable setup range, the minimum value (if the lower limit of the range is not reached) or the maximum value (if the upper limit of the range is exceeded) is set.
