Patent ID: 7995968

Claim:
A method of determining characteristics of a communication device receiver circuit within a scattered field chamber (SFC) that is receiving communications from a base station simulator, the method comprising: controlling movement of a mode stirrer device within the SFC to sequentially move the mode stirrer device to a plurality of different static positions, wherein the different static positions of the mode stirrer device are configured to differently mix polarizations of incident RF fields in the SFC; at each of a plurality of the different static positions of the mode stirrer device, varying the transmission power level from the base station simulator through a plurality of different transmission power levels; at each of a plurality of the transmission power levels, measuring a bit error rate and a received signal strength at which the communication device receives the communications from the base station simulator; and determining an absolute total isotropic sensitivity of the communication device receiver circuit in response to the measured bit error rate, the measured received signal strength, and the associated transmission power levels.
