Abstract

The invention provides a filtering switchover testing device, and belongs to the technical field of test, measurement and control. The filtering switchover testing device solves the problem that switchover measurement and filtering of output signals or input signals of spaceflight equipment can not be realized. A filtering integrated circuit board is arranged inside a shell. A connector head and a connector base are embedded in the left side face and the right side face of the shell respectively. Data connection ends of 62 testing ports on the left side are connected with data connection ends of the connector base through data lines respectively. Data connection ends of 62 testing ports on the right side are connected with permanent connection ends of 62 toggle switches through a data line respectively. Normally-closed ends of the 62 toggle switches are connected with data connection ends of the connector head through a data line respectively. Normally-open ends of the 62 toggle switches are connected with 62 first data input and output ends of the filtering integrated circuit board through a data line respectively. 62 second data input and output ends of the filtering integrated circuit board are connected with data ends of the connector head. The filtering switchover testing device is suitable for testing and protection of input signals or output signals of a device.

Description

technical field [0001] The invention belongs to the technical field of test measurement and control. Background technique [0002] Aerospace and industrial equipment often interfere with the output or input signals of aerospace and industrial equipment during system testing, and it is impossible to test the output or input signals of aerospace equipment, so a test filter adapter is urgently needed. Contents of the invention [0003] In order to solve the problem that the test switching and filtering of the output or input signals of aerospace and industrial equipment cannot be realized, the invention proposes a test filtering switching device. [0004] The test filter adapter device of the present invention includes a connector head, 62 toggle switches, a filter integrated circuit board, 62 test ports on the left side, 62 test ports in the middle, 62 test ports on the right side, and a connector seat and shell; [0005] The filter integrated circuit board is placed insid...
