Setting the channel / EMC bandwidth
(CBW / EBW)
Here you can do the following:
1.
Select the current filter type CBW or EBW (CISPR, MIL-STD-461-F).
2.
Set the channel bandwidth (CBW) or EMC bandwidth (EBW).
3.
Select Oversampling.
Normal and EMC filter types:
The channel bandwidth (CBW) filter type allows you to select a narrow frequency range
with the desired bandwidth from a wideband spectrum and to suppress the remaining
signal components.
Instead of the CBW filter two EMC filters according to the standards CISPR and MIL-
STD-461-F can be selected.
When selecting an EMC filter, following bandwidths are available:
• CISPR: 200 Hz, 9 kHz, 120 kHz, 1 MHz
• MIL: 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz, 1 MHz
The available bandwidths also depend on the Fspan setting.
After selecting an EMC filter type, the label CBW is replaced everywhere in the
corresponding views by the label EBW.
