The Figure 9 “Demodulator settings table” in devices with DVB-S/S2 input consists of the following parameters:
„SAT input“ - A parameter that can switch demodulator off or connect to any available RF input.
“User band” - parameter used in dSCR/SCR Switches.
„Input frequency“ - parameter is a frequency of transponder in MHz.
„Symbol rate“ - parameter is a symbol rate of transponder in kSym/s.

status table
The following information is displayed in the table “Demodulator status”:
“RF level” - RF signal level at the device input. Level indication - approximate.
The values of the following parameters are displayed only if the device 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 device 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 device.
“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.
