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.
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.
The set point of the ATPC regulation (ATPC RSL threshold) must be chosen
considering the link budget. For example if the set point is too high, the remote
transmitter will permanently remain at maximum power. It is recommended to
choose a value at least 15 dB above the 10-6 BER threshold.
In ATPC+ACM the RSL threshold must be set properly in order to ensure that
the maximum throughput capacity is met while ATPC is working. The typical
minimum margin compared to the highest modulation 10-6 BER Threshold, is
somewhere between 7dB (low modulation) to 11dB (high modulation). These
values are for information only and are radio configuration dependent.
Min ATPC Tx power and Max ATPC Tx power
The Min Tx power and Max Tx power, within the Tx Range in the ATPC
management, can be written in the relevant field.
