    • A test method is for determining RF sensitivity of an RF receiver (132) for a plurality of channels extending over a frequency band(s) using an RF source (131) coupled to the RF receiver by an RF communications link (133). 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 nonpredictable RF sensitivity.
    • 测试方法用于通过RF通信链路(133)使用通过RF接收器耦合的RF源(131)来确定在频带上延伸的多个信道的RF接收机(132)的RF灵敏度。 多个通道可以包括具有可预测RF灵敏度的通道和具有不可预测的RF灵敏度的通道。 测试方法可以包括测量具有可预测的RF灵敏度的一个或多个信道的RF灵敏度,以及基于此产生具有可预测RF灵敏度的信道的部分RF灵敏度功能。 该方法还可以包括测量具有不可预测RF灵敏度的信道的RF灵敏度。 另外,可以基于部分RF灵敏度功能并且基于具有不可预测的RF灵敏度的信道的测量的RF灵敏度来为多个信道生成整体RF灵敏度功能。

    • 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 RF 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.
