Abstract

The invention discloses a sensitivity test method and a system based on a frequency modulation (FM) receiver of a mobile terminal. Sensitivity of the FM receiver of the mobile terminal is measured through a signal generator and a wireless general-purpose tester, sensitivity test is conducted by that an audio analyzer is replaced by an audio function of the wireless general-purpose tester, so that a testing person can quickly test the sensitivity of the FM receiver when conducting a radio frequency (RF) test item so as to improve test efficiency and bring great convenience.

Description

technical field [0001] The invention relates to the field of mobile terminal testing, in particular to a sensitivity testing method and system based on a mobile terminal FM receiver. Background technique [0002] Mobile terminals have become very important tools for people, such as mobile phones or tablet computers, and the corresponding mobile terminals have more and more functions. At present, the existing mobile terminals basically support the FM receiver function, and the FM receiver's One of the more important measures of performance is sensitivity. The sensitivity test of the FM receiver belongs to the RF test item, that is, the test item of the radio frequency part. [0003] The sensitivity test of the existing FM receiver usually uses a signal generator and an audio analyzer to test the sensitivity of the FM receiver. When the testers are doing RF test items, that is, the test items of the radio frequency part, there is no audio analyzer, so that the testers cannot...
