3.3 Channel Power Measurement
When Res BW is set to Auto, the resolution bandwidth is auto-coupled to the span. The ratio of
Span/RBW is approximately 106:1 when auto coupled. When Res BW is set to Man, and the
bandwidths are entered manually, these bandwidths are used regardless of other instrument settings
Preset See "RBW Presets" on page 609
State Saved Saved in instrument state
Min 1 Hz
Max 8 MHz is the max equivalent –3 dB RBW, which means that the named RBW (the one shown on the
control etc.) can actually exceed 8 MHz if using a filter other than –3 dB Gaussian
Annotation A “#” mark appears before “RBW” in the annotation when it is switched from Auto to Manual coupling

More Information
When Res BW is set to Auto, the bandwidth selected depends on "RBW Filter Type"
on page 612.
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.
