Abstract

The invention discloses a line loss acquisition method, line loss acquisition equipment and a computer readable storage medium. Aiming at the defects that an existing scheme is inaccurate in line lossvalue and poor in flatness in same frequency band, the line loss acquisition method comprises the steps of computing an average line loss, dispersion and standard variation of each initial line lossvalue after the initial line loss values of a test connection device under a plurality of test channels in a test frequency band is detected, and then correcting each initial line loss value in the test frequency band to acquire the final line loss value. The invention also provides a terminal and a computer readable storage medium, which can ensure that each corrected final line loss value can bedistributed in a converged manner based on the average line loss as much as possible, so that the dispersion between the corrected final line loss values is reduced, and flatness and accuracy of thefinal line loss value in the test frequency band are enhanced. The condition that the radio frequency performance of the terminal based on the final line loss value can be more objective and accurateis ensured, and the production cost is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and more particularly, to a line loss acquisition method, device and computer-readable storage medium. Background technique [0002] With the development of communication technologies, users have higher and higher requirements on the radio frequency performance of terminals. Therefore, in order to ensure that the terminal can communicate normally after leaving the factory and has excellent RF performance, each terminal needs to undergo strict RF testing before leaving the factory. During the RF test, the tester connects the terminal to be tested with the tester through the RF cable and the fixture connection terminal, and then uses the tester to test various parameters that can characterize the RF performance of the terminal to be tested. Among them, the transmit power is a very important detected parameter. When testing the parameter of transmission power, the terminal to be t...
