Radio frequency automatic test system for wireless communication base station

Abstract

The invention provides a base-station radio-frequency automatic test system which comprises a radio-frequency analyzer, a network analyzer, a signal source, a power meter, a severer equipped with automatic test software and a radio-frequency unit comprising coaxial radio-frequency switches as well as filters and attenuators of different specifications. The base-station radio-frequency automatic test system is arranged inside a large-size test cabinet. The operation of the system is under the centralized control of a high-performance workstation. The test software is designed to complete various base-station test items specified in the standard according to user's needs. The base-station radio-frequency automatic test system covers the whole range of the test of various radio-frequency parameters of base station of various communication systems, and maximizes the degree of test automation. Additionally, the base-station radio-frequency automatic test system has the advantages of wide coverage, full test types, high automation degree, easy operation, friendly interface, flexible configuration, convenience for updating along with the modification of the standard, automatic correction function, high test accuracy, and capability of networking several scattered labs via a local area network (LAN) and achieving the effect of test data sharing.

Description

technical field [0001] The present invention generally relates to a test system, and more specifically relates to a radio frequency automatic test system for a wireless communication base station. Background technique [0002] A base station (abbreviated BS) is a high-power multi-channel two-way radio transmitter fixed at a specific location. It is used for low-power channel two-way wireless communication such as mobile phones and mobile phones; the basic function of the repeater is a radio frequency power booster, a radio transmission relay device that enhances the signal during wireless communication transmission; In the mobile communication system, the repeater is located between the base station and the mobile station, and relays and transmits the two-way radio frequency signal between the two, which is used to fill the blind area covered by the base station or extend the coverage area. Unlike the base station, the repeater has no baseband processing circuit, does not d...

Problems solved by technology

[0003] For the RF test of base stations and repeaters, traditional methods often rely on manual connection to switch RF channels, or use standard program-controlled switch units produced by equipment suppliers such as Agilent, R&S, etc.; use manual connection to switch RF The shortcomings of the channel are obvious, that is, the test time is obviously prolonged, which is easy to cause human errors and the repeatability of the test results is not good; if the standard program-controlled switch unit is used to build the radio frequency unit of the base station repeater, its disadvantages are The complexity of the system is too high and the investment is huge, so that the test cost remains high; in addition, manual testing is easy to introduce some human error factors, and the test data results are closely related to the technical level, operation proficiency and subjective factors of the testers. high degree of certainty
