Chapter 3 - Operational Information
DVB-S / DVB-S2 AUTO Modes (ADV and PRM option)
The RD-70 Advanced and Premium demodulators support automatic modulation and coding
mode detection. When the unit is configured for DVB-S or DVB-S2, the minimum
configuration required is L-Band frequency and symbol rate. In DVB-S mode, selecting
QPSK_AUTO or 8PSK_AUTO from modulation mode will automatically detect the coding
scheme for DVB-S modulated carriers. For DVB-S2 modes, selecting AUTO-CCM from the
CCM configuration will automatically detect the modulation and coding scheme for DVB-S2
modulated carriers.
DVB-S / DVB-S2 AUTO Modes (LB option)
The RD-70 with L-Band demodulator (LB) option supports automatic detection of modulation
type and symbol rate on two RF inputs. In fully automatic mode, the minimum configuration
requirement is L-Band frequency. The demodulator is running in fully automatic mode when
the type is set to 'AUTO' and the symbol rate is set to '0' or 'AUTO'.
Notes about demodulator:
Please note that some carriers may not fully acquire if they fall outside of the

allocated resources available by the hardware. Please reference the demodulation

DVB-S2 - Recommended use of Pilots
The use of DVB-S2 pilots within the modulated carrier are recommended under certain
conditions. With the following configurations, Pilots are recommended:
High order modulation schemes: 16APSK and 32APSK
●
Low code rates QPSK: 1/4, 1/3, 2/5, 1/2, and 3/5
●
Low code rates 8PSK: 3/5, 2/3, 3/4, and 5/6
●
Low symbol rates: <5 Mbaud for free running DRO LNB
●
Low symbol rates: <3 Mbaud for Phase Locked DRO LNB
●
How to use RF Profiles (LB option)
The RD has capability to create profiles from the current running RF configuration and load
it at a later time.
To create a profile:
Enter the desired RF parameters required for the profile
