    • A method for determining failure modes of a transceiver (100) includes applying a control signal (121) to a transmitter (130) of transceiver (100). The power level of a transmit signal (131) is proportional to a predetermined voltage level of control signal (121), and is detected by a detector (132) which correspondingly produces a transmit power level indicator (133). A portion of transmit signal (131) is coupled to produce a coupled transmit signal (111) which is received by a receiver (110) of transceiver (100). Receiver (111) produces a receive signal strength indicator (112) corresponding to the power level of coupled transmit signal (111). Voltage levels of received signal strength indicator (112), transmit power level indicator (133) and predetermined voltage level of control signal (121) are stored in a memory means 125, and compared in a controller 126 to determine failure modes of receiver (110) and transmitter (130).
    • 一种用于确定收发器(100)的故障模式的方法包括将控制信号(121)应用于收发器(100)的发射器(130)。 发射信号(131)的功率电平与控制信号(121)的预定电压电平成比例,并由相应产生发射功率电平指示符(133)的检测器(132)检测。 发射信号(131)的一部分被耦合以产生由收发信机(100)的接收机(110)接收的耦合发射信号(111)。 接收器(111)产生对应于耦合发射信号(111)的功率电平的接收信号强度指示符(112)。 接收信号强度指示符(112),发射功率电平指示符(133)和预定电压电平的控制信号(121)的电压电平存储在存储装置125中,并在控制器126中进行比较以确定接收机(110)的故障模式 )和发射机(130)。
