Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a radio frequency environment automatic calibration device. Background technique [0002] With the development of wireless communication technology, the functions of communication equipment are becoming more and more complex, and higher requirements are put forward for the radio frequency testing of wireless communication systems. Especially for 4G and 5G communication systems, the number of radio frequency indicators is large and the requirements for indicators are high. Multiple test environments need to be set up. Moreover, the number of antennas has increased from two antennas to four antennas, eight antennas, and even more than 64 antennas. During the test, the specific performance requirements in the wireless channel environment are higher each time. At present, the test system for measuring wireless devices in the channel environment basically adopts the...
