In this menu, you can choose the channel or frequen cy setting for the adjust-
ment of the RF output. The channel setting covers the range of channels S21 …
C69, the frequency setting covers the range from 42.0 MHz to 860.0 MHz.
The QAM signal is normally transmitted with a bandwidth of 8 MHz. This
means that you can only use the channel centre frequency of the existing
channel raster in the range of channels S21 … C69 (frequency raster 8 MHz).
The CCIR channel raster is 7 MHz in the range of the lower frequency bands
(channels C2 … S20). Therefore the frequency setting is used here. If one uses
the existing channel raster of 7 MHz in these channel ranges, this will result in
interference (overlapping) with the 8 MHz QAM signal packages, thus caus-
ing transmission problems.
For programming in these channel ranges and in the frequency ranges below
them, we recommend starting with channel S21 / 306 MHz going back in
steps of 8 MHz (see frequency table on page 30), or reducing the bandwidth of
the QAM output signal by removing stations using the software PSW 1000.
