Span/RBW
This soft key displays the ratio between the span width and the resolution bandwidth.
The default value is 300, meaning that the span width is approximately 300 times the
resolution bandwidth. The value is approximate because resolution bandwidth filters
come in discrete steps while span width can be set to any value up to the maximum
frequency of the unit. To change the ratio, select this soft key and use the keypad, the
Up/Down arrow keys, or the rotary knob to select a new ratio.
