The embodiment of the invention provides an AAU test method and device and a multi-probe wave-absorbing camera obscura, and the method comprises the steps: obtaining a target calibration result corresponding to a current test frequency point of the multi-probe wave-absorbing camera obscura according to a pre-stored corresponding relation between the frequency point and the calibration result, wherein the calibration result is a calibration result obtained by calibrating a test environment; compensating the test environment according to the target calibration result; in the compensated test environment, testing an active antenna unit (AAU) to be tested through the test probes of the multi-probe wave-absorbing camera obscura, and obtaining the radio frequency index and the wireless index of the AAU to be tested, wherein the AAU to be tested is arranged in the multi-probe wave-absorbing camera obscura, so the problems that in the prior art, when an AAU tests the wireless performance through a standard far field or compact field, the field index requirement is strict, the construction cost is high, testing is complex, and the AAU cannot be applied to batch production testing can be solved.
Description
technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, relate to an AAU test method, device and multi-probe absorbing dark box. Background technique [0002] Traditional base station equipment (complete machine + metal filter) has a radio frequency port at the output end of its own metal filter. The test of its radio frequency index usually adopts the conduction test method, and the test interface is at the radio frequency port of the equipment. [0003] After the emergence of the new form of Antenna Filter Unified (AFU) antenna, the dielectric filter replaces the traditional metal filter and the dielectric filter has been moved up to the antenna. At this time, the "whole machine + filter module" cannot be tested for RF indicators at the conduction station. [0004] At the same time, in order to meet high-speed and large-capacity application scenarios, 5G networks require more accurate active beam coverage. This re...
