Embodiment Construction
[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0046] The present invention aims to overcome the deficiencies of the prior art and provide a method that can reduce human errors in the testing process, lower the entry threshold for testers, facilitate the company to track, manage and control product quality, and make full use of instrument resources. High test efficiency. In the case of changing the test frequency band and changing the test content, the system can complete the automatic test method based on instrument control for the wireless module test process. The invention can realize automatic testing of technical indicators such as communication sensitivity, output power, OBW (effective bandwidth), EVM (vector magnitude error), and power flatness of the wireless communication module.
[0047] Such as figure 1 As shown, the device provided by the embodiment of the present invention i...

The invention relates to a wireless module automatic test device based on instrument control. A code-scanning gun, a computer, a wireless connection tester and a radio frequency / microwave conversion platform are sequentially connected; the wireless connection tester is connected with a wireless test tool; and the computer is connected with the radio frequency / microwave conversion platform and the wireless test tool. The method comprises the following steps: recording information of a tested wireless module by utilizing the code-scanning gun; controlling the wireless test tool to supply power for the wireless module and collect short-circuit voltage to judge whether the wireless module has short-circuit trouble through the computer; carrying out initial configuration on the wireless connection tester, the radio frequency / microwave conversion platform and the wireless module, and reading radio frequency parameters of each channel of the wireless module; carrying out re-configuration and receiving reception success rate of each channel of the wireless module; and judging whether the wireless module has fault according to the radio frequency parameters and the reception success rate of each channel. According to the device and method, instrument resources are fully utilized, and thus production efficiency is improved, and human-made errors in the test process are reduced.
Description
technical field [0001] The invention relates to an automatic test device and method for a wireless communication module, in particular to an automatic test device and method for a wireless communication module based on an instrument control mode of a unified interface. Background technique [0002] With the vigorous development of the Internet of Things in my country, the demand for short-distance wireless communication modules has greatly increased. Especially for the modules used in WIA-PA technology, the usage quantity will also be very huge.
