Embodiment Construction

[0011] Such as figure 1 Shown is a system architecture diagram of a preferred embodiment of the communication device signal receiving sensitivity test system of the present invention. The communication device signal receiving sensitivity test system 10 runs in the test equipment 1 and is used to test the sensitivity of the communication device 20 to be tested. The test equipment also includes a through-axis signal line 12 for transmitting and receiving wireless signals. The communication device 20 to be tested is placed at any position in the test darkroom 2 , and the inside of the test darkroom 2 is equipped with a wave-absorbing material, which is used to shield the signal clutter around the communication device 20 to be tested. The test chamber 2 also includes an antenna 22 for transmitting and receiving wireless signals. The test darkroom 2 can be a standard test darkroom or a non-standard test darkroom. The communication device 20 can be a 3G mobile phone or any other s...

Abstract

The invention relates to a System and method for testing communication device signal receiving sensitivity, which is applied to testing equipment and comprises the following steps: a communication device to be tested is put into a testing dark room; testing parameters are set in the testing device; controlling the testing device to transmit a signal to the communication device to be tested according to the set parameters; calculating the bit error rate; when the bit error rate is in the designated value range, acquiring RSCP of the communication device to be tested at the time; and calculating the signal receiving sensitivity of the communication device to be tested according to the acquired RSCP and the power of CPRCH in the set testing parameters. The invention also provides System and method for testing communication device signal receiving sensitivity.

Description

technical field [0001] The invention relates to a sensitivity testing system and method, in particular to a communication device signal receiving sensitivity testing system and method. Background technique [0002] Signal receiving sensitivity is a basic index to measure the performance of communication devices. Therefore, the accuracy of the signal receiving sensitivity test is extremely important in all test items of the communication device. During the signal receiving sensitivity test, the communication device to be tested needs to be placed in a dark room for testing to maximize shielding from interference from other radio waves. The test darkroom can be divided into a standard test darkroom and a non-standard test darkroom. The standard test chamber must be a standard rectangle, the antenna for sending and receiving signals must be a horn antenna, and the size of the absorbing material used must be specially calculated. The non-standard darkroom can be a standard re...
