Abstract

The invention discloses a method and a device for testing a radio frequency index and a wireless index of an active antenna system. A probe-type test hood based on a near field coupling mode is adopted to test the radio frequency index of the tested active antenna system. The method comprises test hood single body calibration, test hood environment calibration, radio frequency index test, putting the tested active antenna system into the test hood, wherein the test environment is the same as the calibration environment, and carrying out radio frequency test on the tested active antenna system through a radio frequency port of a test probe after compensating the test environment according to the calibrated calibration result. The invention provides the comprehensive testing method at the same time. A space radio frequency (OTA) test is respectively adopted to test spatial characteristic of the active antenna system; and the near field coupling mode is adopted to test the radio frequency index of the active antenna system. The advantages of two testing methods are fully combined, and the defects and problems of the two testing methods are overcome and solved, thereby optimizing the test efficiency and the test cost.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for testing radio frequency indicators and wireless indicators of an active antenna system. Background technique [0002] The traditional base station equipment itself has a radio frequency port. The test of the radio frequency index usually adopts the conduction test method, and the reference point of the test is the radio frequency port of the equipment. [0003] Active Antenna System (AAS) is a base station communication subsystem that integrates multi-channel transceivers and base station antennas. It is an integrated device of antennas and multi-channel transceivers. The interfaces between them are internal interfaces. It is difficult to directly test the RF port, which brings challenges to the test of the active antenna system. [0004] To test the active antenna system using the conduction test method of traditional base station equipmen...
