Abstract

The invention discloses a fast antenna testing device and method based on hardware triggering. The device and method solves the problems of coordinated control of components such as a test turntable, a measurement instrument and a switch unit, and fast testing in a multi-probe antenna test in the prior art. The fast antenna testing device based on the hardware triggering comprises a main control computer, a vector network analyzer, a turntable controller, a triggering controller, a switch matrix, a receiving probe matrix, the test turntable and an antenna to be tested. By means of the fast antenna testing device and method based on the hardware triggering, communication delay is little, switching time of a switch is short, switching frequency is small, and total test time is short.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a fast antenna testing device based on hardware triggering, and also to a fast antenna testing method based on hardware triggering. Background technique [0002] For the antenna test, from the perspective of the hardware system, its functional block diagram is as follows figure 1 As shown, it includes a main control computer 5, a vector network analyzer 6, a test turntable 7, a turntable controller 1, a transmitting antenna 8 and an antenna to be tested 9, and each part completes the test work through coordination and cooperation. Taking the far-field test as an example to introduce the specific test process of the system: firstly, the antenna 9 to be tested is set up on the test turntable 7, and the transmitting antenna 8 and the antenna 9 to be tested are placed relative to each other at a certain distance; The signal that the vector network analyzer 6 produces is radiated out...
