BW
Filter Type
When CISPR RBW is selected, the RBW is set to normal RBW as
below. The VBW couples with RBW.
When Filter Type is set to Normal, Res BW is normally coupled to
Span.
Sweep time is coupled to RBW in a non-zero span. If Sweep Time is
set to Auto, then the sweep time is changed as the RBW changes,
to maintain amplitude calibration.
Video bandwidth (VBW) is normally coupled to RBW. If VBW is set
to Auto, then the VBW is changed as the RBW changes.
When 200Hz CISPR filter is selected and Quasi-Peak detector is
set to off, the sweep mode is FFT.
If CISPR RBW is selected, the marker counter and gated sweep
function are disabled.
