why in spectrum analyzer bandwidth settings it is preferable the relation between Resolution Bandwidth (RBW) & Video Bandwidth (VBW) to be 1/3 ? means if the RBW is 30 KHz , it is preferable to have VBW with 10 KHz .
and if VBW filter is a Low passfilter , why lowering the value will slow down the speed of sweeping ?
