1. A method for performing radio frequency (RF) source-affected RF receiver testing on a platform having a plurality of RF dependent devices, the method comprising:
connecting a set of the plurality of RF dependent devices to an RF signal communication network;
connecting a plurality of acquisition antennas to the RF signal communication network;
connecting a real time spectrum analyzer to the RF signal communication network;
continuously monitoring an ambient electromagnetic state at the platform using the real time spectrum analyzer and the plurality of acquisition antennas;
operating an RF source to transmit an RF signal, wherein the RF source is one of the RF dependent device in the set;
estimating an operating parameter of each RF dependent device in the set using the real time spectrum analyzer;
identifying a signal of interest using the estimated operating parameter and the ambient electromagnetic state; and
identifying an affected RF dependent device using the signal of interest.
