Problems solved by technology

[0004] The first way is to calibrate through the vector network comprehensive tester. This method has high accuracy but cannot measure the end of the radio frequency line connected to the mobile phone, and the vector network comprehensive tester is expensive, which makes the calibration cost very high. And this method Unable to perform consistency correction for the deviation of the mobile phone comprehensive test instrument
[0005] Method 2. Calibrate through the gold phone. The specific gold phone is to select a mobile phone with better indicators in a batch of mobile phones. When testing, the gold phone is connected to the mobile phone comprehensive test instrument through the radio frequency line, and the radio f

Embodiment Construction

[0043] In view of the defects in the prior art, the embodiment of the present application proposes a calibration method for a mobile phone production test system, which is applied to a wireless terminal test system including a standard comprehensive tester and a radio frequency line, such as figure 1 shown, including the following steps:

[0044] Step 101. Test the radio frequency line by testing equipment to obtain the line loss of the radio frequency line;

[0045] Specifically, the test equipment can be: a receiver and a module with the function of a vector network analyzer. Of course, it can also be other equipment, as long as the line loss of the radio frequency line and the instrument difference of the standard comprehensive tester can be obtained. .

[0046] Specifically, the process of obtaining the line loss includes:

[0047] Connect the test equipment to the instrument connection end of the radio frequency line; send a signal to the radio frequency line through th...

Abstract

The invention discloses a method and a device for calibrating a mobile phone production test system. The method comprises: performing tests radio frequency lines through a test device, to obtain line loss of the radio frequency lines; performing tests on a standard general-purpose tester through the test device, to obtain instrument error of the standard general-purpose tester; and determining a calibration value based on the line loss and the instrument error, so that the standard general-purpose tester can calibrate the standard general-purpose tester and the radio frequency lines based on the calibration value, that is, the radio frequency lines and the standard general-purpose tester are calibrated through the test device. The device can rapidly measure while ensuring precision. The method and the device can be suitable for large-scale test wireless terminal systems.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a calibration method and equipment for a mobile phone production test system. Background technique [0002] In the prior art, it is necessary to test the radio frequency index of the radio frequency signal of the mobile phone. Only the mobile phone that meets the requirements can be sold in the market. In the prior art, the radio frequency index of the mobile phone radio frequency signal is detected by the mobile phone comprehensive tester, but in the When testing, the mobile phone comprehensive tester needs to connect to the mobile phone through the radio frequency line, and the radio frequency line also has signal attenuation. Therefore, when testing the radio frequency index of the radio frequency signal of the mobile phone, the radio frequency line needs to be calibrated [0003] However, in the prior art, there are the following two w...
