Abstract

The invention discloses an integrated audio and radio frequency test method and a system thereof. The method comprises the following steps: generating an audio test signal and a radio frequency test signal; while receiving the audio test signal, receiving the radio frequency test signal and respectively generating an audio feedback signal and a radio frequency feedback signal by a module to be tested; and obtaining and analyzing the audio feedback signal and the radio frequency feedback signal. The audio test signal and the radio frequency test signal are simultaneously loaded on the module to be tested, and the audio feedback signal and the radio frequency feedback signal generated by the module to be tested are analyzed, so that the module to be tested can simultaneously carry out an audio test and a radio frequency test, the test environment of the module to be tested is guaranteed to be consistent with the actual application scene when the module to be tested is installed on a terminal, the product quality can be guaranteed, and the test efficiency is improved; and the tests can be carried out in a working station, thereby saving the manpower cost and further improving the test efficiency.

Description

technical field [0001] The invention relates to the field of testing, in particular to an audio-frequency integrated testing method and system thereof. Background technique [0002] Today's portable devices have audio and RF components assembled together, such as speakers and antennas, which require testing during the production of the components themselves. [0003] In the public document with the application number 200710175254.7, a mobile communication terminal audio testing system and its testing method are proposed; in the patent document with the application number 200710202050.8, a mobile phone radio frequency testing method is proposed. The above two files realize audio testing and radio frequency testing respectively, but for products assembled with audio components and radio frequency components, two workstations are required for testing, the test cost is high, and audio and radio frequency cannot be tested at the same time. Completely simulate the end product req...
