6.12.9 Change, BUC/LNB, Rx/LNB, DC & REFERENCES Menu

	Rx/LNB:
	1:DC Supply[15V] 2:10M Ref[Off]
	Change, BUC/LNB, Rx/LNB, DC & References Menu
DC SUPPLY	The P310 L-Band modem can supply either 15V or 24V at 500mA to the LNB `up
	the coax` or `line powered`. The option available here are Off, 15V or 24V.
	CAUTION: Needless to say severe damage may occur if a DC supply (or the
	wrong voltage DC supply) is fed to a LNB not configured for being `Line powered`.
10M REF	The internal 10MHz reference may similarly be sourced from the modem `up the
	coax` to the LNB. The only option available here is On or Off.

6.12.10Change, BUC/LNB, Rx/LNB, SHF FREQUENCIES Menu

Similar to the BUC option, this screen is available on both 70MHz/140MHz P300 modems and P310 L-Band modems, and allows the modem to be set to display and edit the final SHF frequencies instead of the IF frequencies. When the LNB Type has been set to a predefined type (ie not None or Other) then this setting is done automatically and the menu option to manually set the frequency shift is not presented.

Set downconverter freq shift to display & edit Rx freq at antenna:[Yes] 1=Yes 2=No

Change, BUC/LNB, Rx/LNB, SHF Frequency Menu 1

If Yes is selected then the following screen is displayed:

Freq shift of downconverter:[13050 MHz]

(0-65535MHz) ??.??? (YES)

Change, BUC/LNB, Rx/LNB, SHF Frequency Menu 2

Once set all Rx IF frequencies displayed or edited include the frequency shift of the LNB or downconverter chain.

Note this manual entry of SHF Frequency shift always assumes a low side Local Oscillator (LO) and therefore displays the SHF Frequency = LO + IF. There is no means to enter a High Side LO, where the SHF frequency received would be LO - IF Frequency (unlike the situation where the modem is told it has a Std C band LNB, and knows that a high side LO is used).
