Hi again,
I recently found out that the Bandwidths of the XCVR 2450 Daugtherboard are as
follows for the RX and TX side respectively:
Bandwidths (Hz):
RX: 15M, 19M, 28M, 36M; (each +-0, 5, or 10%)
TX: 24M, 36M, 48M
Can someone elaborate on these values please and how to decide upon which one to
use? As I can understand, this is dependent on the specific application,
however, I am puzzled as to why they are different since these values correspond
to the bandwidth allowed in the bandpass filter prior to transmission/reception.
These filters are programmable low-pass filters which operate at baseband. In general, you just need to set them wide enough for the signals you wish to deal with.
