The QAM signal is transmitted with a bandwidth of
8 MHz. This means that you can only use the channel cen-
tre frequency of the existing channel raster in the range of
channels S21 … C69 (frequency raster 8 MHz). The fre-
quency raster is 7 MHz in the range of the lower channel
ranges (channels S2 … S20). If one uses the existing chan-
nel raster here, this will result in interference (overlapping)
of the 8 MHz QAM signal packages and thus transmission
problems. For programming in this channel range, we rec-
ommend to calculate the output frequency of the QAM
modulator,
… starting with the upper output frequency of the Cas-
sette listed in the “Specifications” going back in steps
of 8 MHz, or
… starting with the lower output frequency of the Cas-
sette listed in the “Specifications” moving up in steps
of 8 MHz.
