8 Channel Power Measurement
BW
Couplings
Sweep time is coupled to the RBW. As the RBW changes, the sweep time (if set to Auto) is changed
to maintain amplitude calibration.
Video bandwidth (VBW) is coupled to the RBW. As the resolution bandwidth changes, the video
bandwidth (if set to Auto) changes to maintain the ratio of VBW/RBW (10:1).
When the 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 analyzer settings.
