Select the desired QAM using the “+” and “-” buttons. QAM stages 16, 32, 64, 128 and 256 are available.
Note: If different QAM stages are available, it is advantageous to select the lower stage (e.g. if 256 and 64 are
available, select 64). If an exclamation mark “!” is shown beside the output symbol rate (i.e. the input data
rate is too large for the output data rate setting), the output symbol rate or the QAM stage must be increased
to ensure correct operation.

1.10 Selecting the QAM stage
The output signal QAM stage is selected using the “<” and “>” buttons.
1.11 Selecting the modulation signal for the QAM modulator
The modulation signal (mode) for the QAM modulator is selected in the QAM stage sub-menu .
The output signal QAM stage is selected using the “<” and “>” buttons.
Pressing the “Sub-menu” button activates the sub-menu; pressing the “Sub-menu” button again deactivates it.

The following settings are available:
Mode SAT Sig
Normal mode, the satellite input signal is transmodulated. If there is a fault on
the input signal, only fi ll bytes (0xFF) will be modulated
PRBS
Test mode. The QAM signal is modulated with the PRBS-23 sequence.
Normal mode is unavailable in this setting
CW
Test mode. Sine-wave signal for levelling using simple signal meters.
Normal mode is unavailable in this setting
