The solid cursor indicates the current configuration choice. The modem
automatically adjusts, but the default value is Average. Note that:
•
With Average, the unit sets the pilots and header to the average power
band of the transmitted constellation (QPSK, 8PSK, 16APSK, or 32APSK)
per DVB-S2.
• With Peak, the unit sets the pilots and header to the outer ring of the
transmitted constellation (QPSK, 8PSK, 16APSK, or 32APSK).
