Description

Test system and method of mobile terminal {SYSTEM AND METHOD FOR TESTING OF MOBILE PHONE}

The present invention relates to a test system and method for testing the performance and operation of a portable terminal.

A portable terminal is a device capable of transmitting and receiving voice or data using a communication circuit composed of a plurality of integrated circuits (ICs) and electrical elements.

Such portable terminals will be released only to terminals that meet certain performance criteria through performance measurement after assembly is completed.

In the production site and A / S site of such a portable terminal, a dedicated performance test apparatus is used to measure the performance and call quality of the terminal, and in operating the terminal performance test apparatus, a control PC is usually used.

According to the terminal performance test system and the method according to the prior art, since the performance test apparatus uses a dedicated interface, a dedicated GPIB (General Purpose Interface Bus) board must be connected to the control PC for remote control from an external control PC. . In addition, a GPIB to RS-232C converter box must be used externally to use a universal serial interface in the control PC.

The control PC transmits a control command to the terminal performance test apparatus through the GPIB port, and loads a test execution program stored in the mounting memory of the terminal performance test apparatus to perform a test.

Therefore, in order to measure the performance of the portable terminal, the output signal of the communication circuit is blocked from being transmitted to the test apparatus through the RF connector.
