Line loss calibration method, device and system and computer readable storage medium

Abstract

The invention discloses a line loss calibration method, device and system and a computer readable storage medium. The line loss calibration method comprises the steps of: when it is detected that theradio frequency test system is in a first connection state, controlling a first port of the wireless communication tester to transmit a first signal with first preset power, and obtaining first receiving power of the first signal received by the power meter; when detecting that the radio frequency test system is in a second connection state, controlling the first port of the wireless communicationtester to transmit a second signal with a second preset power, and obtaining a second receiving power of the second signal received by the second port of the wireless communication tester; and calculating to obtain a line loss compensation value according to the first preset power, the first receiving power, the second preset power and the second receiving power, and calibrating the radio frequency test system based on the line loss compensation value. According to the invention, the automatic test of the line loss compensation value and the automatic calibration of the radio frequency test system can be realized, and the calibration efficiency and the accuracy of the calibration result can be improved.

Description

technical field [0001] The present invention relates to the field of radio frequency technology, in particular to a line loss calibration method, device, system and computer-readable storage medium. Background technique [0002] At present, wireless technologies such as consumer electronics, Bluetooth, Wi-Fi (Wireless-Fidelity, wireless fidelity), and cellular networks have become very popular. It is usually necessary to conduct radio frequency conduction tests on electronic devices using wireless technology to check whether their radio frequency performance meets the requirements. [0003] During the test process, there is often line loss. In order to ensure the accuracy of the test results, the standard sample calibration method will be used to test and obtain the line loss compensation value for calibration. Specifically, the tester selects a standard gold plate, and controls the standard gold plate to send a radio frequency signal to the wireless communication tester ac...

AI Technical Summary

Problems solved by technology

This calibration method is not only inefficient, but also has the problem of poor accuracy of test results due to the long-term use of the standard gold plate due to wear and tear.

Therefore, the line loss calibration scheme in the prior art has the problems of low calibration efficiency and poor accuracy of calibration results
