• Connect the test receiver to the RF output or the test output of the head-end
station.
• Set the output channel / output frequency of the cassette (page 19) and adjust
the TV test receiver to this channel / frequency.
• Switch on the channel strip (modulator) if necessary (page 19). For each chan-

In order to prevent interference within the head-end station and the cable sys-
tem, the output level of the cassette must be decreased by 10 dB compared to
an analogous level at 64 QAM, and by 4 dB compared to analogue cassettes
at 256 QAM.
• Measure the output levels of the other cassettes and tune them to a uniform
output level using the appropriate level controls or software dependent on
the head-end station used. Please regard the assembly instructions of the
respective head-end station.
