3.9 SEM Measurement
Res BW
Sets the resolution bandwidth used to calculate the power in the reference channel.
The Channel Resolution BW can be set manually or put into auto mode.
MSR Auto RBW:
In the MSR Mode, resolution bandwidth is predefined for each radio format. When
carriers are configured with multiple radio formats, the narrowest RBW is selected.
