More Information
When Res BW is set to Auto, the bandwidth selected depends on "RBW Filter Type"
on page 600.
Only certain discrete resolution bandwidths are available. The available bandwidths
are dependent on Filter Type or EMC Standard. If an unavailable bandwidth is
entered with the numeric keypad, the closest available bandwidth is selected.
In some PowerSuite measurements, in the LTE-Advanced (both FDD and TDD) and
5G NR modes, when Res BW is in Auto, the resolution bandwidth is predefined
based on the corresponding bandwidth of the single carrier, as shown in the table
below. In the Multi-carrier case, the narrowest RBW among the active carriers is
used.
