Description

Technical Field

[0001] This invention relates to the field of communication testing technology, and in particular to a method, equipment, and computer-readable storage medium for testing line loss. Background Technology

[0002] In existing technologies, wireless products, such as Wi-Fi modules and Bluetooth modules, generally require power consistency calibration during the production testing phase. If the compensation for line loss in the testing environment is inaccurate, it will cause a deviation in the actual power calibration of the product. For example, if the compensation for line loss is too small, the actual power calibration will be too high; conversely, if the compensation for line loss is too large, the actual power calibration will be too low. This affects the quality of products shipped in batches. Therefore, all wireless calibration environments need to be tested for environmental line loss compensation to ensure its accuracy.

[0003] Currently, the line loss testing solution mainly consists of two steps: First, set up the test environment, calibrate the network analyzer, set the required frequency points on the network analyzer, manually connect the environmental RF cable to the test port of the network analyzer, use the network analyzer test environment, record the line loss values ​​of the required frequency points, and manually compensate the recorded frequency point line loss values ​​to the line loss file of the test tool's gold board mode; then, restore the test environment to the normal environment, run the line loss test mode on the test fixture using the gold board, and after the test is completed, generate new line loss values ​​to overwrite the manually entered line loss values.

[0004] As can be seen, the above-mentioned gold plate mode line loss test requires manual inspection of environmental line loss using a network analyzer. Furthermore, the calibration of the network analyzer, frequency setting, and writing of line loss values ​​all require manual operation. This process is cumbersome, requires high operator skills, has low execution efficiency, and operators cannot accurately or promptly judge whether the measured values ​​are reasonable or whether the RF environment is abnormal, resulting in a high error rate.

[0005] In conclusion, improving the efficiency of line loss testing, reducing manpower and material costs, and enhancing the accuracy and timeliness of anomaly detection have become pressing technical challenges. Summary of the Invention

[0051] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0052] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0053] Figure 1 This is the first flowchart of the line loss testing method of the present invention. This embodiment proposes a line loss testing method, which includes:

[0054] S1. Connect the wire to be tested to the test port of the comprehensive tester;

[0055] S2. The comprehensive tester performs line loss calculations at each frequency point in its environmental inspection mode, and the results of the line loss calculations are then compensated to the line loss file.

[0056] S3. Perform line loss testing in the metalworking line loss mode of the comprehensive tester, and overwrite the environmental inspection line loss in the line loss file with the new line loss file generated by the line loss test.

[0057] Optionally, in this embodiment, while automatic line loss compensation is possible when using a gold-plated automatic testing system for environmental line loss, the gold-plated mode requires manual inspection of environmental line loss using a network analyzer. The calibration, frequency setting, and line loss value writing operations of the network analyzer are all manual, which is cumbersome, demands high skill levels from production line workers, has low efficiency, and workers cannot judge the reasonableness of measured values ​​or the abnormality of the RF environment, resulting in a high error rate. Therefore, this embodiment proposes a fully automated method for inspecting the environment, testing line loss using a gold-plated system, and automatically writing the line loss data to a *.txt (text file), thereby greatly improving the efficiency and accuracy of line loss calibration and reducing the difficulty of operation for workers. Furthermore, this embodiment considers that in existing solutions, manually inspecting the environment and measuring line loss using a network analyzer can determine the reasonableness of the line loss value, which can be used to judge whether the RF environment is normal. However, this process depends on the individual skills of the workers. The automatic inspection and gold-plated testing solution of this embodiment can automatically determine the frequency point line loss difference within the frequency band, thereby efficiently and accurately identifying and intercepting abnormal states of environmental RF cables or RF devices.

[0058] Optionally, in this embodiment, firstly, the antennas and frequencies to be measured in the line loss mode are configured on the test tool; then, the test line loss gold board transmits the mode power to obtain the antenna and corresponding frequency power required for testing modules such as WIFI, that is, the line loss mode is fixed in terms of mode and rate; then, all the measured antenna frequencies and powers are written to the gold board file; finally, the test tool is set to the environmental line loss inspection mode, and the RF port is connected according to the software pop-up prompts of the tool. The comprehensive test instrument automatically measures the environmental line loss and automatically writes it to the line loss file *.txt. Further, the environment is reconnected to the aforementioned comprehensive test instrument, and the gold board is used to run the equipment line loss test mode to automatically test the environmental line loss, generate a new line loss file, and overwrite the environmental inspection line loss.

[0059] As can be seen, in this embodiment, production line workers use the equipped testing tools to automatically inspect environmental line loss, verify the measured values ​​through the testing tools, and automatically compensate for line loss, avoiding measurement and line loss input errors caused by human factors, thereby improving testing efficiency and accuracy. Furthermore, compared to existing solutions that require manual inspection of environmental line loss using a network analyzer followed by line loss testing using a comprehensive tester, this embodiment's automated testing solution only requires automatic inspection using a comprehensive tester followed by line loss testing. This reduces the skill requirements for employees operating the instruments and saves on the cost of using the network analyzer.

[0060] The beneficial effects of this embodiment are as follows: By connecting the cable under test to the test port of the comprehensive tester; the comprehensive tester performs line loss calculations at each frequency point in its environmental inspection mode, and compensates the line loss calculation results into the line loss file; the comprehensive tester performs line loss testing in its metal-machine line loss mode, and the new line loss file generated by the line loss test overwrites the environmental inspection line loss in the original line loss file. This application implements an adaptive line loss testing scheme, which greatly improves the execution efficiency of line loss testing, reduces manpower and material costs, and enhances the accuracy and timeliness of abnormal state detection.
