ABSTRACT:
In a satellite transponder architecture employing digital signal processing, a power monitor samples the data stream of carrier frequency samples on board the transponder and computes a power level for each of the carriers. This provides accurate and high frequency resolution power measurements within the communications link. These measurements are useful for computing critical transponder characteristics such as the effective isotropic radiated power (EIRP), receiver sensitivity, uplink sensitivity, operating points and, in a system using a phased array antenna, the total and component powers for each beam. The power monitor eliminates problems associated with external measurement methods, and improves the overall accuracy and reliability.
