Set OBW Span
[:SENSe]:OBWidth:FREQuency:SPAN <freq>
[:SENSe]:OBWidth:FREQuency:SPAN?
Enables you to specify the range of integration used in calculating
the total power from which the percent occupied bandwidth is then
calculated. The analyzer span will be set to the same value as the
OBW Span for the measurement. OBW Span should be set to
approximately 2 times the expected occupied bandwidth result.
If you have an adjacent channel, you should not set the OBW span
to 2X your occupied bandwidth. The OBW measurement first
computes all the power in the span and then 99% of that. Diamond
markers are set around the bandwidth, and the occupied
bandwidth results is displayed in the data window. If the power of
the adjacent channel is included in the calculation for the 100%
power, the OBW result will be too high. The OBW Span should be
set narrow enough to encompass the channel of interest and
exclude any unwanted adjacent channels.

OBW:FREQ:SPAN 10 MHz

Turn on/off Max Hold
[:SENSe]:OBWidth:MAXHold OFF|ON|0|1
[:SENSe]:OBWidth:MAXHold?
Enables you to turn maximum hold trace feature On or Off for the
measurement. Maximum hold displays and holds the maximum
responses of a signal.
*RST: Off
Example:
OBW:MAXH ON
