Problems solved by technology

[0002] Nowadays, mobile phones have entered thousands of households, but few people know that mobile phones have to undergo countless tests before leaving the factory to ensure the stability of their functions. Among them, the radio frequency parameter calibration test is one of the more important tests. The test is to ensure the stability of the radio frequency of the mobile phone, and try to avoid the situation that the signal of the mobile phone is weak or even no signal under normal network conditions; the existing radio frequency parameter calibration test is due to poor contact of the line, fixture, and connector at the instrument end, and improper antenna matching. Factors such as these affect the results of mobile phone calibration and the pass rate of mobile phone RF calibration comprehensive test

Embodiment 1

[0035] figure 2 It is an operation flowchart of a production line calibration comprehensive test method of the present invention, in figure 1On the basis of determining the type of the production machine, when the production machine is a GSM mobile phone, the step S3 also includes a process: reading the maximum value of the radio frequency power of each frequency band in the radio frequency power table of all frequency bands of the production machine, And extract the maximum value of the radio frequency power among all the maximum values. Only read the maximum RF power value from the mobile phone that has the greatest impact on the calibration comprehensive test results as the judgment condition for whether the production machine passes the production line calibration comprehensive test, which can greatly speed up the work efficiency, and at the same time ensure the power consistency of the production machine to avoid Batch rework caused by calibration power exceeding standa...

Embodiment 2

[0045] image 3 It is a schematic diagram of a production line calibration comprehensive testing device of the present invention, the calibration comprehensive testing device 10 includes a control terminal 1 for presetting the range of radio frequency power parameters of the production machine, a calibration comprehensive testing instrument 2 for calibrating the production machine, and a A detection tool 3 that reads the maximum value of the RF power of the production machine and compares the maximum value of the RF power with the preset range of RF power parameters.

[0046] Because the present invention directly reads the maximum value of radio frequency power that is not interfered by the test environment inside the production machine, it can avoid power loss due to factors such as lines, fixtures, instrument end connectors, antenna matching, etc. in the mobile phone radio frequency test system. Affect the result of mobile phone calibration, leading to the problem of calibr...

Abstract

The invention discloses a production line calibration comprehensive test method and a production line calibration comprehensive test device. The comprehensive test method comprises the steps that S1: radio frequency power parameter range of a production machine is preset; S2: the production machine is calibrated; S3: the maximum radio frequency power value of the production machine is read; S4: and the maximum radio frequency power value and the radio frequency power parameter range are compared, and the production machine passes production line calibration comprehensive testing if the maximum radio frequency power value is within the radio frequency power parameter range. Production line calibration comprehensive test pass rate of the production machine can be enhanced.
