Frequency setting

If the PEDQ 3005 QMX

cassette is used, the "Frequency setting" menu is dis

played instead of the "Channel setting" menu.

Bx 1
112.00 MHz

OUTPUT:

The QAM signal is normally transmitted with a bandwidth of 8 MHz. That

means that you can only use the mean channel frequency of the existing chan-

nel raster in the range of channels S21 … C69 (frequency raster 8 MHz). The

channel raster is 7 MHz in the range of the lower frequency bands (channels

C2 … S20).

That is why the frequency setting is used here. If one were to use the normal

channel raster in these channel ranges, this would result in interference (over-

lapping) with the 8 MHz QAM signal packages, thus causing transmission

problems.
