Embodiment Construction

[0055] In order to test the function of receiving FM signals, the present application provides a test method, device, medium and equipment for the function of receiving FM signals. In order to better understand the solution provided by the embodiment of this application, here is a brief description of the principle of this solution:

[0056] Firstly, a preset frequency modulation signal is transmitted by a preset frequency modulation signal transmitter, so that the intelligent terminal to be tested receives and plays the frequency modulation signal. The audio device records the FM signal played by the smart terminal to be tested and analyzes the frequency response and signal-to-noise ratio of the recorded FM signal. If the analyzed frequency response is within the preset frequency response range and the signal-to-noise ratio is within the preset signal-to-noise ratio range, it is determined that the FM signal receiving function of the smart terminal to be tested is normal; whe...

Abstract

The invention discloses a test method, device, medium and equipment of a frequency-modulated signal receiving function, and relates to the technical field of the mobile phone production test. The frequency-modulated (FM) signal receiving function is tested. The method comprises the following steps: emitting a FM signal in the preset frequency through a preset FM signal emitter, recording a FM signal played by a to-be-tested intelligent terminal, analyzing the frequency response and signal-to-noise ratio of the recorded FM signal; if analyzing that the frequency response is in the preset frequency response range and the signal-to-noise (SNR) ratio is in the preset SNR range, determining that the FM signal receiving function of the to-be-tested intelligent terminal is normal; if analyzing that the frequency response is not in the preset frequency response range and / or the SNR is not in the preset SNR range, determining that the FM signal receiving function of the to-be-tested intelligentterminal is abnormal. Therefore, the test can be accomplished without being judged through the auditory sense of the human eye, the test is judged according to the SNR and the frequency response range, the accuracy of a test result is improved when the automatic test is realized.

Description

technical field [0001] The present application relates to the technical field of mobile phone production testing, and in particular to a testing method, device, medium and equipment for receiving FM signal functions. Background technique [0002] The testing methods for frequency modulation signals in the prior art mainly rely on manual testing. After using the mobile phone to receive the FM broadcast, the test is carried out by artificially listening to the sound played by the earphone. Going to the next test requires repeating the above operation. Such a method has a very high labor cost and low efficiency. In addition, after the testers are tired of hearing, it is easy to cause inaccurate test results. Contents of the invention [0003] Embodiments of the present application provide a test method, device, medium and equipment for a function of receiving FM signals, which are used for automatic testing of the function of receiving FM signals. [0004] In the first asp...
