For QPSK Tuner:
- LNB Local Oscillator (L.O.) Freq:
enter the frequency of the LNB in MHz.
- Satellite Freq:
edit the satellite down link frequency in MHz. The IF frequency will be
calculated automatically.
- Symbol Rate:
enter the QPSK symbol rate.
- LNB Voltage:
select the correct LNB voltage output of the F-connector: Off, 13 V, 18 V. <A>
- LNB 22KHz:
activate the LNB 22 kHz control signal to the LNB: On or Off. <B>
- Note:
please contact the local satellite operator for the satellite frequency and symbol rate.
<A> Normally, 13V switches the LNB to receive Vertical/Left hand polarization
while 18V receive Horizontal/Right hand.
<B> Normally, 22KHz control signal switches the LNB to receive high band if any.
For QAM Tuner:
- Constellation:
enter the modulation mode of the QAM signal.
- Frequency:
enter the frequency of the QAM signal in MHz.
- Symbol Rate:
edit the symbol rate to the proper value in KBaud.
For COFDM Tuner:
- Frequency:
enter the proper frequency of the COFDM signal in MHz.
For DVB-S2 Tuner:
- LNB Local Oscillator (L.O.) Freq:
enter the frequency of LNB in MHz.
- Satellite Freq:
edit the satellite down link frequency in MHz. The IF frequency will be
calculated automatically.
- Symbol Rate:
enter the QPSK/8PSK symbol rate.
- LNB Voltage:
select the correct LNB voltage output of the F-connector: Off, 13 V, 18 V. <A>
- LNB 22KHz:
activate the LNB 22 kHz control signal to the LNB: On or Off. <B>
- Note:
please contact the local satellite operator for the satellite frequency and symbol rate.
<A> Normally, 13V switches the LNB to receive Vertical/Left hand polarization
while 18V receive Horizontal/Right hand.
<B> Normally, 22KHz control signal switches the LNB to receive high band if any.
