Setting the frequency offset (fine tuning)
• If necessary press the
▶
button until “
0
” also appears in
the display.
• Use the keys
to set the offset (
-64
…
+64
).
• Use the
◀
/
key to return to the channel setting.
Note:
Using the Cassette HDMT 473 MX the menu “Setting the
output frequency” appears instead of “Setting the output
channel”.

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
(channels S2 … 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 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.
