Back Off Power
Back off power from Max power in the EEPROM
Use_TPC_Power = 1
Power is determined according to the maximum power stored in the EEPROM minus the following back off. The
back off can be modified differently for each rate:

Using Regulatory Constraints in Closed Loop Tx Mode
Figure 12
Regulatory Constraints in Closed Loop Tx Mode
For EMI testing, there is an option to limit the transmitted power according to the EMI standards.
To use this mode:
1. Consider the regulatory (see
) and hardware (see
) limitations.
2. Select the Use regulatory constraints mode.
5.5.1
Regulatory Limitations
Regulatory limitations are imposed by the ETSI, FCC, and Telec standards for different channels and BW.
The reglimits.csv file is provided (in C:\Program Files\Lantiq\DUT\Regulatory_Constrains) with all the FCC, ETSI
and Telec limitation for all the channels. The DUT GUI uses the information in this table to define the max output
power allowed for each of the bands and frequencies. An example is shown in the following table.
