to change the video bandwidth within the active function area, ranging from 1Hz to
20 MHz, which is stepped by 1, 2, 3, 5 and 10. The resolution bandwidth can be changed with the
number keys, step keys and knob. The shaded character indicates the currently selected mode. When set
as Auto Off, press [Video BW Auto Man] to select Auto On and return to auto mode.

More description:
comprising [Gaussian] and [Flattop]. In general, the signal/spectrum uses Gaussian
filter, i.e., use filter approximate to the Gaussian shape to complete filtering of Res BW. If the flat top
filter is used, the signal/spectrum analyzer adopts filter approximate to the rectangular shape to complete
filtering of resolution bandwidth. The response time of flat top filter is about 3 times of that of the
Gaussian filter. The sweep speed of the flat top filter is smaller than that of the Gaussian filter. The flat
top filter has better selectivity than the Gaussian filter and therefore is more capable of distinguishing two
signals with unequal amplitude.
