Setting the resolution / EMC bandwidth (RBW / EBW)

Here you can select the filter type and set the resolution bandwidth (RBW) or channel bandwidth (CBW) respectively.

 

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 (Scan) Spectrum 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.
