Abstract

The invention relates to matrix switch equipment capable of being configured at will on the basis of the USBTMC protocol. The matrix switch equipment comprises a control module, a power supply, a switching network and a USB equipment interface, wherein an upper computer is connected with the matrix switch equipment through the USB equipment interface, the control end of the switching network is connected with the control module, the input end of the switching network is connected with test equipment, and the output end of the switching network is connected with a device to be tested. By the adoption of the matrix switch equipment capable of being configured at will on the basis of the USBTMC protocol, the matrix switch equipment can be conveniently connected with the upper computer through the USB interface and can be conveniently integrated with an existing automatic test system, matrix switches are configured according to different devices to be tested to so that different connection modes can be achieved, test efficiency is improved, test time is saved, and the application range is wider.

Description

technical field [0001] The invention relates to the field of automatic test systems, in particular to the field of control of matrix switch equipment during testing, and specifically refers to a matrix switch equipment that can be configured arbitrarily based on the USBTMC protocol. Background technique [0002] The matrix switchgear is an important part of the automatic test system and the key equipment to realize the automatic test. The matrix switch is mainly used for signal switching, and flexibly allocates system test resources according to the test requirements of the actual DUT (Device Under Test, device under test). With the development of LTE (Long Term Evolution, long-term evolution technology) and 802.11ac communication standards, the testing of MIMO (Multiple In Multiple Out, multiple input multiple output system) antennas is increasingly dependent on having a matrix switch device, so The versatility, ease of use, and scalability of matrix switchgear are becomin...
