Problems solved by technology

The reason is that the consistency of the parts we manufacture mobile phones does not meet the requirements of our technical specifications, which will affect the quality of mobile phone calls, call environment and other issues, these problems will directly affect our work, life and study
In practice, the mobile phone RF test system produces power loss due to factors such as lines, fixtures, connectors at the instrument end, antenna matching, etc., which will directly affect the results of mobile phone calibration

Embodiment Construction

[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0040] Such as figure 1 As shown, the process of making a calibration machine is as follows: first select a mobile phone with good RF performance, set the calibration tool to make a calibration machine mode, the calibration tool sets the mobile phone according to the frequency band, channel and power level set by the user, and reads the The real power corresponding to the mobile phone, after reading the real power, check whether the mobile phone has other channels, if so, set the frequency band, channel and power level of the mobile phone again, and then read the corresponding real power again until the detection There is no other channel for the mobile phone, and the real power is stored in the address specified by...

Abstract

The invention relates to a method for automatically calculating compensation for a mobile-phone radio frequency testing system. The method comprises the following steps that S100, a mobile phone is made into a calibration machine by using a calibration tool, and true power of the mobile phone is written into the calibration machine; S200, the true power of the calibration machine is read by using the calibration tool, and testing power of the calibration machine in the mobile-phone radio frequency testing system is measured by using a general-purpose tester; S300, compensation for the mobile-phone radio frequency testing system is calculated, and compensation for the mobile-phone radio frequency testing system is equal to the value obtained by subtracting the true power of the calibration machine from the measured testing power of the calibration machine in the mobile-phone radio frequency testing system. By means of the method for automatically calculating compensation for the mobile-phone radio frequency testing system, the situation that calibration results of the mobile phone are affected because the mobile-phone radio frequency testing system produces power loss due to circuits, clamps, connectors on the instrument side, antenna matching and other factors can be avoided, and more precise radio frequency calibration of the mobile phone is achieved.

Description

technical field [0001] The invention relates to a mobile phone radio frequency test system, in particular to a method and equipment for automatically calculating the compensation of the mobile phone radio frequency test system. Background technique [0002] Mobile phones have gradually become a necessity in people's lives in today's society, and people have become increasingly inseparable from their mobile phones. With the development of technology, mobile phones are also changing with each passing day, from 2G to 2.5G to 3G... However, no matter how the mobile phone is updated, in the current mobile phone manufacturing process, RF calibration must be performed. The reason is that the consistency of the parts we manufacture mobile phones does not meet the requirements of our technical specifications, which will affect the quality of mobile phone calls, call environment and other issues, these problems will directly affect our work, life and study . In practice, the mobile ...
