Setting the resolution / EMC bandwidth (RBW /
EBW)
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 ) or EMC bandwidth
( Auto EBW ).
3. Set the Fspan -> RBW function On or Off .
4. 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
(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 .
