Abstract

The invention provides a multichannel 5G base station testing device and a multichannel 5G base station testing method. The test device comprises: a human-computer interaction control interface, a high-performance CPU processing unit, a baseband signal generation and analysis processing unit, a radio frequency transmitting extension set and a radio frequency receiving extension set; the human-computer interaction control interface is connected with the high-performance CPU processing unit, the high-performance CPU processing unit is connected with the baseband signal generating and analyzing processing unit, and the baseband signal generating and analyzing processing unit is respectively connected with the radio frequency transmitting extension set and the radio frequency receiving extension set through high-speed optical fiber interfaces. According to the invention, multi-channel testing is carried out on the uplink and the downlink of the 5G base station at the same time, so that thetesting efficiency is greatly improved, and the production period of the 5G base station is shortened; the remote control test mode can prevent testers from being in a base station operation environment for a long time, so that the harm to the testers is reduced; meanwhile, the multichannel testing device greatly reduces the production cost of the 5G base station.

Description

technical field [0001] The invention relates to the field of base station testing, in particular to a multi-channel 5G base station testing device and testing method. Background technique [0002] With the advent of the 5G era, the number of wireless base stations has increased sharply, and 5G base stations have multi-antenna characteristics based on Massive MIMO technology. During the production and use of wireless base stations, it is inevitable to conduct consistency tests on the radio frequency indicators of wireless base stations. Traditional The test method relies on a signal source and a spectrum analyzer, and can only test a single channel at a time, so the test efficiency is low. Especially in the base station production line, the single-channel test technology greatly reduces the production efficiency, and requires a lot of cost in the test process. Contents of the invention [0003] Aiming at the problems of low efficiency and high cost in existing base station...
