2.8 Bandwidth-efficient assignment of cable channels with low bandwidths
(SelecPlex

®

)

Channels with low bandwidths are the result of filtering out stations which are
not required. These “narrow” channels can then be arranged in one channel to
save space. To do this, activate the “Setting the output frequency” menu (assign-
ment outside the official channel raster).

—> The required bandwidth (in kHz) is roughly equal to the symbol rate

(kSymb/s) plus 20% in MHz.
