A CSV file(configurationfile)per transmitter are created by the NOC engineer based

on the installation parameters such as line lengths, antenna type etc.

The TX output power level setting is contained in the CSV file.

The output power is adjusted by the ‘attenuation’ setting This value in the CSV file is

calculated by a formula to set the output power (not to exceed 30W EIRP). The

variables used in the calculation include PA Gain (Gpa), TX Antenna Gain (Gant), TX

filter insertion loss (ILflt), internal cable loss (ILint), external cable loss (ILext), and

transceiver output power (PTCVR).

EIRP (W) = 10^((PTCVR ‐ ILint+Gpa‐ILflt‐ILext+Gant)/10)/1000
