4.5.3.1 List of Available Channel Filters
The channel filters listed in the following table are available as resolution filters (soft-
key RES BW) after activation with the softkey FILTER TYPE.
For filter type RRC (Root Raised Cosine) the indicated filter bandwidth describes
the sampling rate of the filter.
For all other filters (CFILter) the filter bandwidth is the 3-dB bandwidth.
Operating Manual 1302.6163.12 - 03
NORMAL (3dB)
The resolution bandwidths are implemented by Gaussian filters with a set 3 dB
bandwidth. These bandwidths correspond to the noise bandwidth approximately.
For bandwidths up to 100 kHz, digital bandpass filters are used.
EMI (6dB)
The resolution bandwidths are implemented by Gaussian filters with the set 6 dB
bandwidth and correspond approximately to the pulse bandwidth.
For bandwidths up to 1 MHz, digital bandpass filters are used.
