The QAM signal is 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 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” moving up in steps of 8 MHz.
