Paradise P300 specifications Change, BUC/LNB, Tx/BUC, SHF Frequency Menu

6.12.4Change, 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.

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

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

If Yes is selected then the following screen is displayed:

Freq shift of upconverter:[13050 MHz]

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

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

Once set all Tx IF frequencies displayed or edited include the frequency shift of the BUC or upconverter chain.

6.12.5Change, 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.

Modem +13.7[Gain]=SHF [EIRP] in [dBW] 1:System Gain 2=TxPwr/EIRP 3=dBm/dBW

Change, BUC/LNB, Tx/BUC, SHF Power/Units Menu

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.
