Figure 14. Demodulator
status table
The following information is displayed in the table “Demodulator status”:
“RF level” - RF signal level at the module input. Level indication - approximate.
The values of the following parameters are displayed only if the module has synchronized with the input signal.
“Modulation standard” - detected standard of the input signal. Possible values of the standard: DVB-S, DVB-S2.
“Frequency” - intermediate frequency (for DVB-S/S2) at the module input.
“Modulation” - modulation scheme of the input signal. Possible values of the modulation scheme: QPSK, 8PSK (for DVB-S/S2).
“FEC” - forward error correction.
“SNR” - RF signal/noise ratio at the input of module.
“VBER” - bit error rate after Viterbi corrector. To get the signal without any errors at the output of the tuner, VBER shall not
exceed 2Е-4.
“PER” - ratio of the MPEG2 transport error packets to the whole number of packets. If the number of error packet is equal
to zero, the opposite value to whole number of packets is displayed. Packet counters are reset during RF input parameters
update.
“Input bitrate” - bitrate of the input signal.
