3 Spectrum Analyzer Mode
3.10 TOI Measurement
Span:3dB RBW
Selects the ratio between span and resolution bandwidth.
Normally, Span:3dB RBW (Auto) selects a Span:3 dB RBW ratio of 106:1. If you
manually enter the ratio, the toggle on Span:3dB RBW changes to Man. This
enables you to manually select ratios more suitable for certain measurements.
When Span:3dB RBW is manually selected, it may be returned to the coupled state
by setting the toggle on RBW:3 dB RBW back to Auto. This may also be done by
pressing "Auto Couple" on page 2017 or by performing a Preset.
