Setting the Resolution Bandwidth
The Resolution Bandwidth (RBW) sets the filter response of the analyzer’s IF stages. This is defined as the
width of the filter response at its 3 dB (50%) point from maximum. Increasing the RBW allows faster sweep
times while decreasing the RBW allows you to view lower noise levels.
1. Press the BW icon on the main menu bar, or press the Bandwidth key on the instrument front panel, to
display the Bandwidth menu below:
2. Select Auto RBW mode or press in the RBW parameter field and use the keypad to enter the desired
bandwidth, then select the appropriate terminator from the fly-out menu.
