Here you can do the following:
1.
Set the resolution bandwidth (RBW) or EMC bandwidth (EBW).
2.
Enable automatic setting of the resolution bandwidth (Auto RBW).
3.
Set the entry mode (RBW Entry).

Select the filter type (Filter Type).
Normal and EMC filter types:
The normal filter types resolution bandwidth (RBW) or channel bandwidth (CBW) allows
you to select a narrow frequency range with the desired bandwidth from a wideband
spectrum and to suppress the remaining signal components.
In the task modes Spectrum (Scan) and RT Spectrum, it is possible to use EMC filters
instead of the normal filters. When using EMC filters the following bandwidths can be
selected: 10 Hz, 100 Hz, 200 Hz, 1 kHz, 9 kHz, 10 kHz, 100 kHz, 120 kHz, 1 MHz.
The available bandwidths also depend on the Fspan setting.
After selecting the filter type EMC, the text RBW or CBW is replaced everywhere in the
corresponding views by the text EBW.
