6.3 Demodulator
Statistics
The demodulator statistics shows a number of monitoring parameters of the
received carrier for each stream present in that received carrier in case of DVB-S2.
Figure 17 – Screenshot of the Demodulator Statistics overview.
6.3.1
FEC-rate and mod
This monitoring parameter displays the detected modulation and FEC used for
each of the DVB-S2 streams in the received carrier.
6.3.2 Frame
type
This monitoring parameter displays the detected frame type (normal or short
frames) that is used for each of the DVB-S2 streams in the received carrier.
6.3.3 Pilots
This monitoring parameter displays whether pilot tones were inserted for each of
the DVB-S2 streams in the received carrier.
6.3.4
BB frame count
This monitoring parameter displays the number of baseband frames that are
decoded by the demodulator board for each of the DVB-S2 streams in the received
carrier.
6.3.5
Uncor frame count
This monitoring parameter displays the number of uncorrected baseband frames
by the demodulator board for each of the DVB-S2 streams in the received carrier. It
indicates that the link margin is too low or that channel distortions caused by
saturation or non-linearity caused the decoder not to be able to correctly decode
frames.
