Problems solved by technology

Step-by-step settings are easy to miss or make mistakes, and even the settings are not the same when testing at different times, resulting in deviations in test results
Too many settings are also unfavorable for engineers who are initially exposed to audio testing
In addition, the efficiency of calculating and processing a large amount of test data in manual mode is also very low.
Generally speaking, the efficiency of this manual testing method is low, especially when a large number of products need to be tested in batches or consistency, such low efficiency is unbearable
[0008] In the prior art, there are still some instruments similar to the SYS2522A audio analyzer. The test method is manual, and the instrument needs to be manually set up step by step. Due to the large number of settings, the efficiency is low, and setting errors are prone to occur. , the problem of different settings before and after

Abstract

The invention discloses an audio index automatic testing device, which includes an audio analyzer for measuring the audio index of a device to be tested, and also includes: a user interaction unit for receiving test requirement information input by a tester, in which the test requirement information Contains relevant information about the test items requested by the tester; the instrument setting unit is used to automatically generate the instrument setting instructions of the audio analyzer according to the test requirement information; the instruction parsing and issuing unit is used to receive and analyze the described Set instructions, issue to the audio analyzer and control the audio analyzer. The invention can effectively improve the test efficiency and the accuracy of test results.

Description

technical field [0001] The invention relates to testing technology in the field of communication, in particular to an automatic testing device for audio frequency indicators. Background technique [0002] When realizing the test of the audio frequency index, it is usually to use the audio frequency analyzer to carry on at present. Among them, Audio Precision's SYS2522A audio analyzer is a leading product in the industry. Its function is relatively powerful. It is controlled by a computer and can be used to measure and test analog and digital audio and serial digital audio interface formats. [0003] All signal generation and signal analysis can be performed inside the SYS2522A audio analyzer, and the sampled signals used for waveform display and FFT (Fast Fourier Transform Algorithm, Fast Fourier Transform Algorithm) analysis are also stored in its internal DSP (Digital Signal Processing , digital signal processing) model. [0004] see figure 1 , the panel (not shown) of ...
