Receiver
Additionally, in this section, you are able to set the dual RF receiver parameters including
the Satellite Frequency, Symbol Rate, LNB Frequency, and LNB Voltage (Polarization) with
accurate values. Then you can press the "Apply" button to save your settings.
 SATELLITE FREQUENCY (MHz): this is the satellite down conversion
frequency, every transponder has one frequency, and you can get this
parameter from the satellite program provider.
 SYMBOL RATE (KBaud): every transponder has one symbol rate; you can
get this parameter from the satellite program provider.
 LNB Frequency: this is the LNB's local oscillation (LO) frequency, every
LNB have one or two oscillation frequencies which can be obtained from the
LNB provider, or you can check on the LNB label. The value is between
5000 and 6000.
 LNB Power Supply: LNB voltage is the power that supply to the LNB in
order to receive satellite signal with different polarization. Generally 18V is
for Horizontal while 13V is for Vertical.
 LNB 22 KHz: Generally this is used to control 22KHz switch, typically used
for LNB with double L.O. in Ku band. "ON" is for high L.O and "OFF" is for
low L.O.
Sometimes the parameters may change; it is advisable to check through
