Change, BUC/LNB, Tx/BUC, SHF Power/Units Menu
6.12.4 Change, BUC/LNB, Tx/BUC, SHF FREQUENCY Menu
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
BUC Type has been set to a known Paradise BUC and the modem has the FSK communications option
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 Tx IF frequencies displayed or edited include the frequency shift of the BUC or upconverter
chain.
6.12.5 Change, BUC/LNB, Tx/BUC, SHF POWER/UNITS Menu
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 power instead of the IF carrier level.
It allows the user to set the system Gain or Loss after the modem, so that the modem can then display and
edit the Tx carrier level in terms of either the Tx Power or EIRP, measured in dBm or dBW. The system gain
or loss can be set from -99.9dB to +99.9dB. Options for TxPwr/EIRP &dBm/dBW are only available once
the System Gain has been set to other than zero. When zero the default units are TxPwr indBm.
This screen is not available on the L-Band modem with FSK when the Tx BUC Type has been set to a
known Paradise BUC and the modem / BUC configured to operate as a Terminal, as here the modem /
BUC work in a closed loop mode and compensate for whatever the system gain varies to be, in order to
keep the power measured at the BUC constant.
