摘要： A method for testing a radio frequency (RF) receiver may include measuring a plurality of bit error levels for the RF receiver at a given RF frequency. The method may further include applying a Huber function to the measured plurality of bit error levels to generate a bit error ratio (BER) estimate for the RF receiver. The method would also include using the BER estimate to generate a sensitivity for the RF receiver.

摘要： A test method is for determining RF sensitivity of an RF receiver for a plurality of channels extending over a frequency band(s) using an RF source coupled to the RF receiver by an RF communications link. The plurality of channels may include channels having a predictable RF sensitivity and a channel(s) having a non-predictable RF sensitivity. The test method may include measuring an RF sensitivity for one or more of the channels having the predictable RF sensitivity, and generating a partial RF sensitivity function for the channels having the predictable RF sensitivity based thereon. The method may further include measuring an RF sensitivity for the channel(s) having the non-predictable RF sensitivity. Additionally, an overall RF sensitivity function may be generated for the plurality of channels based upon the partial RF sensitivity function, and based upon the measured RF sensitivity for the channel(s) having the non-predictable RF sensitivity.

摘要： A test method is for determining total isotropic sensitivity (TIS) of a mobile wireless communications device using an RF source controllable to a plurality of source values having a relatively small uncertainty associated therewith. The mobile wireless communications device may includes an antenna and a RF receiver coupled to the antenna and outputting an RSSI value having a relatively large uncertainty associated therewith. The method may include measuring a sensitivity of the RF receiver, and measuring an antenna gain pattern for the antenna based upon controlling the RF source to respective source values causing the RE receiver to generate a same target RSSI value as the RF source and wireless communications device are angularly moved relative to one another to thereby reduce the relatively large uncertainty of the RSSI value. The TIS may be determined based upon the measured sensitivity of the RF receiver and the measured antenna gain pattern.
