3. Frequency
The system can operate with different types of ODUs according to the RF band and
to the channel arrangement. There are ODUs that can manage only one shifter or
several predefined shifters.
In the Shifter field, select the suitable shifter.
In the Tx frequency field, enter the suitable Tx frequency (the Rx frequency is
automatically calculated by using the entered Tx frequency and the shifter).
The Rx frequency field will displays the calculated Rx frequency, but, by selecting
the Allow Rx Frequency Tuning check box this frequency can be changed in ±+5
MHz increments to implement the "Exotic" shifter configuration, if required.
4. Tx Mute
To mute the transmitter, select the Mute check box.
Note: In a 1+1HSB configuration in Single NE mode with 7705 SAR, in order to mute the
entire mw-link a "TX-Mute" command shall be applied to both Main and Spare radios.
5. Transmit Power Control Mode
Select the Mode: RTPC or ATPC.
6. RTPC settings
→ Tx power without Adaptive Modulation
If the ATPC is disabled, the Tx Power field is available. The Tx Power range is
displayed in the screen.
In this field, enter the new value within the allowed transmitted power range.
→ Tx Power with Adaptive Modulation
You can modify only the Tx power relevant to the lowest modulation scheme. In
this field you must enter the constant power, which will be used with the lowest
modulation.
Note: The same power value will be used by the other modulation schemes.
7. ATPC settings
The ATPC cannot be set with ACM (only with FCM).
→ ATPC Remote RSL Threshold
The value of the low power threshold can be changed by writing the new value
in the field. When the Rx power is equal to this power the ATPC algorithm starts
to operate.
