5. Set the input signal spectrum inversion setting (I/Q), which allows the operator
to track and selected inverted or non-inverted digital signals.
When set to Auto, received digital signals are tracked and inverted for correct
selection, as required. When set to Inv (inverted), the received digital signal is
always inverted. Conversely, when set to NonInv (non-inverted), the received
digital signal is never inverted.
6. The 22 KHz Control is only applicable for dual-band LNB applications. It sets
whether or not the 22 KHz tone is available. The selections are On, Off, or Auto
(if downlink frequency is greater/less than the crossover frequency, the 22KHz
tone is automatically set to on/off). The default is Off.
7. The LNB Power setting determines if power is provided via the input to an
external LNB connection.
You can set the LNB Power to Off, 18-H, 13-V, H-NIT, or V-NIT. The default is
18-H. If LNB Power is set to V-NIT or H-NIT, the signal polarization is
automatically read from the NIT. Power will not be applied to the LNB if LNB
Power is set to Off.
Note: LNB power must be on if DiSEqC is required.
For more information, see LNB Power Settings, on page 4-25.
8. Enter the Network ID of the uplink signal the receiver is to receive when using
this preset. You can obtain the network ID from your service provider. The
default is 1.
9. Set the Local Oscillator Frequency #1 (LO Freq 1), which sets the satellite
antenna LNB local oscillator #1 frequency. For C-Band application, set to 5.15
GHz. For Ku-band single LNB, enter LO Freq and set LO Freq 2 and Crossover
Frequency to 0.0. For Ku-band dual LNB, enter LO Freq 1, LO Freq 2 and
Crossover Frequency. The default is 10.75 GHz.
10. Set the Local Oscillator Frequency #2 (LO Freq 2), which sets the satellite
antenna LNB local oscillator #2 frequency. This option is only used in dual-band
LNB applications. LO Freq 2 must be greater than LO Freq 1. The default is 0.0
GHz.
11. Enter the Crossover Frequency. This is an internal threshold frequency used for
selecting the LO1 or LO2 frequency, depending on the current downlink
frequency settings. This option is only used in dual-band LNB applications. The
default is 0.0 GHz.
