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 .
6.12.10 Change, 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.
If Yes is selected then the following screen is displayed:
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).
