Options for LNB Type, and DC & References are only offered on L-Band modems.

Each option is defined in the following paragraphs.

The table below specifies the parameters for the listed LNB types:

Description

None

Std C

Std Ku

10.95-11.7G

11.2-11.7G

11.7-12.2G 12.25-12.75G

Low Frequency Limit	High Frequency Limit	Frequency Shift
Modem IF +/- limits around user set SHF Frequency Shift
Modem IF +/- limits around user set SHF Frequency Shift
3.635 GHz	4.200 GHz	* 5150 MHz
10.950 GHz	11.450 GHz	10000 MHz
10.950 GHz	11.700 GHz	10000 MHz
11.200 GHz	11.700 GHz	10250 MHz
11.700 GHz	12.200 GHz	10750 MHz
12.250 GHz	12.750 GHz	11300 MHz

As with the BUC’s, the difference between None and Other is that with Other the operator can configure the modem to supply a 10MHz reference and a DC PSU to the LNB. With None, these options are not available.

*Note the `Std C` LNB uses a high side Local Oscillator (LO), and the received SHF Frequency is LO - IF Frequency (not LO + IF as with most other bands). This is somewhat academic as from V3.85 onwards this is handled automatically and the modem displays the correct SHF frequency. Note however that with the LNB Type set to None or Other, there is no way to manually enter a SHF offset which uses a High Side LO.
