"Input frequency" - the frequency of the terrestrial or cable transponder in kilohertz.
When the tuner is locked to the DVB-T2 transponder with multi PLP modulation, the additional parameter "PLP number"
is displayed in the "RF input" table. When the "Modulation standard" set to DVB-C, the "Preamplifier power" parameter
is hidden and power for the RF preamplifier is switched off; instead of the "Input bandwidth" parameter the "Symbol rate"
parameter is displayed. Enter the value in kilo symbols per second.

Once the different data values have been entered, click on Update to conclude the input settings.
7.3.2. Input status table
The following information is displayed in the table “Input status” (Figure 12).
“Lock status” ”
Locked
” - the streamer module has synchronised with the input signal; "Unlocked” – the streamer module
has not synchronised with the input signal.
“Input level” - RF signal level at the module input. Level indication – approximate.
The values of the following parameters are displayed only if the streamer module has synchronised with the input signal.
“Modulation standard” – detected standard of the input signal. Possible values of the standard: DVB-S, DVB-S2 (sdi410C,
sda410C); DVB-T, DVB-T2, DVB-C (sti410C, sta410C).
“Frequency” – intermediate frequency (sdi410C, sda410C) or RF frequency (sti410C, sta410C) at the module input.
“Modulation” – modulation scheme of the input signal. Possible values of the
modulation scheme: QPSK, 8PSK (sdi410C, sda410C); QPSK, QAM16, QAM32,
QAM64, QAM128, QAM256 (sti410C, sta410C).
“Modulation mode” – OFDM modulation mode of the input signal (sti410C, sta410C
only). Values: 8k or 2k.
“FEC” – forward error correction.
“Guard interval” – guard interval of OFDM signal (sti410C, sta410C only).
“Symbol rate” – the symbol rate of the satellite transponder in kilo symbols per
second (sdi410C, sda410C only).
“SNR” – RF signal/noise ration 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.
