2.2.2 DVB-S2 L-Band Modulator Setup Procedure
The modulator parameters are specific to the receiving satellite you are using. Make sure you
have all the parameters you need to set-up the modulator.
Configure the basic parameters for the Ellipse L-Band modulator.
To set up a link with the following parameters:
■ DVB-S2 Scheme / 8PSK 2/3 FEC and modulation type
■ Symbol Rate: 10,000,000 symbols per second [sps]
■ L-Band frequency: 950,000 Hz
■ LO frequency: 14,000,000 Hz
■ Spectrum inversion: Direct
■ Carrier and Modulator operation mode: C+M Manual Restore
1. Navigate Root > L-Band Modulation and Up Converter on the front panel.
2. Select Modulation Scheme to display the Modulation Scheme menu.
