Problems solved by technology

[0004] At present, in the process of performing radio frequency testing on signal-approved LTE base stations, for different radio frequency test items and standards, it is necessary to manually install corresponding radio frequency links to meet the test requirements. Sometimes, it is necessary to complete a radio frequency test. Manually carrying multiple test links, this test method is not only inefficient, but also manually carrying test links will introduce measurement errors and affect the accuracy of test results
[0005] And in the process of manually carrying the test link, measurement errors will be introduced, which will affect the accuracy of the test results
Moreover, at this stage, the function of the RF conformance switching unit is single, and it is impossible to complete the test indicators of all standards for model approval.

Abstract

Embodiments of the invention provide a method and a device for a radio frequency test on a signal check long term evolution (LTE) base station. The device comprises a function link unit and an attenuation filtering unit. The function link unit is used for selecting and switching on a function link through a coaxial switch according to the rules of the radio frequency test of the signal check LTE base station, performing compensation on a to-be-test signal of the signal check LTE base station though the connected function link and transmitting the compensated to-be-test signal to the attenuation filtering unit. The attenuation filtering unit is used for performing attenuation and filtering on the compensated to-be-test signal through an attenuator and a filter which are switched on, and then transmitting the attenuated and filtered to-be-test signal to the function link unit. Through adoption of the method and device, the problem that different test items need different signal processing paths in radio frequency test on the LTE base station is solved, problems caused by setting up of test links by manual work in the test process is solved, and the test accuracy and test efficiency are improved.
