The Transmit Power submenu includes the following options:

4.2.6.2.8.1.1 Transmit  Power 
In the AU, the Transmit Power parameter defines the fixed transmit power level 
and is not part of the ATPC algorithm.  
In the SU, the Transmit Power parameter defines the fixed transmit power level 
when the ATPC algorithm is disabled. If the ATPC Option is enabled, the value 
configured for this parameter serves for setting the initial value to be used by the 
ATPC algorithm after either power up or losing synchronization with the AU.   
The minimum value for the Transmit Power Parameter is -10 dBm (the ATPC may 
reduce the actual transmit power of the SU to lower values). The maximum value 
of the Transmit Power Parameter depends on several unit properties and 
parameters: 
„ 
The HW revision of the unit 
„ 
The Maximum Allowed Tx Power as defined for the applicable Sub-Band.  
„ 
The Maximum EIRP as defined for the applicable Sub-Band, together with the 
value of the Antenna Gain. In certain countries the Maximum EIRP of some 
equipment types cannot exceed a certain value. In these cases the Transmit 
Power cannot exceed the value of (Maximum EIRP – Antenna Gain). 
„ 
Maximum Tx Power parameter (in SU only) 
For information on how to view the Sub-Bands supported by the unit and the 
supported parameters’ values and options, refer to section 
4.2.2.4
The unit calculates the maximum allowed Transmit Power according to the unit 
properties and parameters listed above, and displays the allowed range when a 
Transmit Power parameter is selected. 
For each modulation level, the unit will use as transmit power the minimum 
between this parameter and the maximum Tx power allowed by the HW and the 
Country Code for the specific modulation level. 
The default Transmit Power is the highest allowed value.
