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.

摘要： A test method is for determining RF path loss between an RF source and an RF receiver. The RF source may transmit RF power values at a relatively fine granularity, and the RF receiver may generate RSSI values at a relatively coarse granularity and have an unknown hysteresis about each transition between adjacent RSSI values. Hysteresis edges may be determined about a given RSSI value transition at the RF receiver by sweeping RF power values transmitted from the RF source in increasing and decreasing directions. A relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values may be determined using the hysteresis transition edges. The RF path loss for a given channel may be determined based upon a given RSSI at a given RF power value and the relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values.

摘要： A test method is described for determining radiated radio frequency (RF) receiver sensitivity may include determining a bit error rate (BER) versus traffic channel (TCH) power level function for an initial channel, determining an estimated TCH power level for a subsequent channel based upon the BER versus TCH power level function and a desired BER, and measuring a BER of a subsequent channel based upon the estimated TCH power level. The method may further include comparing the measured BER to the desired BER and using a difference therebetween along with the BER versus TCH power level function to determine a next estimated TCH power level, and repeating measuring and comparing if the difference is greater than a threshold to thereby determine a TCH power level in the subsequent channel corresponding to the desired BER.
