Abstract:
1. A radio access point testing apparatus comprising: an access terminal function portion which includes a transmitter part and a receiver part of a communication terminal in a radio communication system, and which serves to test a radio access point; either of a receiver of one loop and receivers of two loops, for receiving forward signals that are transmitted from said access terminal function portion and said communication terminal; a transmitter for transmitting reverse signals that are transmitted to said access terminal function portion and said communication terminal; a path switch part for effecting switching so as to connect an input end of said receiver to an antenna or to terminate the input end, and for switching paths of the signal from said transmitter and the signal toward said receiver; and an access point controller which controls said access point; wherein said access point controller receives a test start command, terminates the input end of said receiver by said path switch part in compliance with the command, and connects a desired one of said transmitter and said receiver with said access terminal function portion, so as to control either or both of: (1) a receiver sensitivity measurement in which a packet error rate is adjusted into a predetermined range, and in which a reception sensitivity is obtained on the basis of transmission power of said access terminal function portion after the adjustment; and (2) a measurement path diagnosis which acquires a first reception power value of said receiver in the case of connecting said receiver with said transmitter part of said access terminal function portion, and a second reception power value of said access terminal function portion in the case of connecting said transmitter with said receiver part of said access terminal function portion, and in which failures of said receiver and the signal path are diagnosed depending upon whether or not a difference between the first reception power value and a predetermined first reception power expectation, and a difference between the second reception power value and a predetermined second reception power expectation lie within predetermined ranges, respectively.
