Notes:
1. Adjusting the RF Level such that it exceeds the nominal RF level when measured at
the APEX RF Connector may degrade RF performance.
2. For proper function of the internal RF Power Level detector, RF Outputs must be
TERMINATED with 75 Ohms. Unterminated RF Outputs may cause an RF Low Alarm to
be generated.
Alpha values for Annex A and B are as follows:
FEC Mode
Annex A DVB
Annex A DVB
Annex B DCII
Annex B DCII
Annex C*
Annex C*
*Annex C specifies Alpha = 13%. The APEX utilizes 12% for Annex C, which results in a
QAM signal skirt bandwidth that is slightly below the normal value for Annex C.
