Sweep and Function Settings
BW
Sets the parameters such as RBW (Resolution Bandwidth) and VBW (Video
Bandwidth).
RBW
Sets the resolution bandwidth (RBW) to distinguish two signals whose frequencies
are close with each other.
Remarks:
⚫ Reducing RBW can gain a higher frequency resolution, but will also prolong the
sweep time (when sweep time is set to Auto, it will be affected by both RBW and
VBW).
⚫ You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,
refer to descriptions in "Parameter Setting".
Note: When "Detector Type" is "Quasi Peak", or the "Filter Type" is
"EMC", the available values of RBW can only be 200 Hz, 9 kHz, 120 kHz, or 1 MHz.

: If option RSA3000-BW1 is installed, the available range is from 1 Hz to 10 MHz.
RBW Mode
Sets the coupling mode of RBW.
Remarks:
⚫ When you set RBW Mode to "Auto", RBW is in auto coupling state. Its value
changes with the span (non-zero span), and the value is determined by
span/RBW ratio. You can set RBW Mode to "Manual" or directly set the RBW
value to change the coupling mode.
⚫ When you perform the Preset operation, the coupling state is Auto.
