Problems solved by technology

However, the related technology has the following disadvantages: 1) the cost of professional measuring instruments is relatively high; 2) the loss value varies with different machines, instruments, cables and motherboards, so in the mass production process of mobile phones, It is necessary to use professional measuring instruments to measure the loss value of each set of machines separately, and measure each machine, each instrument, and each frequency band once, resulting in complex measurement operations and low efficiency; 3) The measured loss The value is a set of fixed values, which cannot be adjusted dynamically in real time. If the cable or instrument is replaced, it needs to be re-measured, which consumes manpower and material resources

Embodiment Construction

[0060] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0061]In order to solve the technical problems in the related technologies, the embodiment of the present disclosure provides a measurement method, the method includes: obtaining the reference loss value of the machine; using the reference loss value to calibrate a preset number of motherboards respectively, and obtaining the preset indicators of each motherboard When the calibration v...

Abstract

The present disclosure relates to measurement methods and devices. The method includes: obtaining a reference loss value of the machine; using the reference loss value to calibrate a preset number of motherboards respectively, and obtaining calibration values ​​of preset indicators of each motherboard; when the calibration values ​​of preset indicators of each motherboard conform to a normal distribution , calculate the difference between the target value of the preset index of each motherboard and the expected value of the normal distribution; adjust the reference loss value according to the difference to obtain the target loss value of the machine. The disclosure can dynamically adjust the loss value of each machine in real time without using professional measuring instruments to measure the loss value of each machine one by one, which can reduce the cost of measurement, simplify the measurement operation, and improve the efficiency of calibration and testing. Increase productivity.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a measuring method and device. Background technique [0002] In the calibration and testing process in the mass production of mobile phones, it is usually necessary to measure the loss of machines, instruments and radio frequency cables. A reasonable loss value can greatly improve the yield rate of calibration and testing. [0003] In related technologies, professional measuring instruments such as power meters and other measuring instruments are mainly used for measurement at present. However, the related technology has the following disadvantages: 1) the cost of professional measuring instruments is relatively high; 2) the loss value varies with different machines, instruments, cables and motherboards, so in the mass production process of mobile phones, It is necessary to use professional measuring instruments to measure the loss value of each set of machines se...
