Measuring method and device

Abstract

The invention relates to a measurement method and device. The method comprises the following steps: acquiring a reference loss value of a machine; respectively calibrating a preset number of mainboards by using the reference loss value, and obtaining a calibration value of a preset index of each mainboard; when the calibration value of the preset index of each mainboard conforms to normal distribution, calculating a difference value between a target value of the preset index of each mainboard and an expected value of the normal distribution; and adjusting the reference loss value according tothe difference value to obtain a target loss value of the machine. According to the invention, the loss value of each machine can be dynamically adjusted in real time, a professional measuring instrument does not need to be used for measuring the loss value of each machine one by one, the measurement cost can be reduced, the measurement operation is simplified, the calibration and test efficiencyis improved, and the production efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular, to a measurement method and device. Background technique [0002] In the calibration and testing process during the mass production of mobile phones, it is usually necessary to measure the loss of machines, instruments and RF cables. A reasonable loss value can greatly improve the yield of calibration and testing. [0003] In the related art, professional measuring instruments, such as a power meter 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) since the loss value varies with different machines, instruments, cables and motherboards, 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, and measure...

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
