The QAM signal is transmitted with a bandwidth of 8 MHz.
This means that you can only use the channel centre fre-
quency of the existing channel raster in the range of chan-
nels S21 … C69 (frequency raster 8 MHz). The frequency
raster is 7 MHz in the range of the lower channel ranges
(≤ channel S20)
. If one uses the existing channel 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 recommend 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” mov
ing up in steps
of 8 MHz.
