Problems solved by technology

The test fixtures for testing VPX signals in the prior art are all single customized printed boards. The problem is that the user needs to remove the backplane or sub-board module from the VPX chassis for testing, which leads to troublesome disassembly and assembly, and the test fixture The performance is simplified, the test range is limited, and all test points cannot be included. It is necessary to customize test fixtures for different signal points according to different users, resulting in low test efficiency and high cost.

Abstract

The invention discloses a VPX digital signal test device comprising a shell, transfer printed boards, and a signal transfer board. The transfer printed boards are inserted into printed board slots of the shell in sequence. The signal transfer board is inserted into a Vita plug connector of one transfer printed board through a Vita socket connector. A backplane signal is led out to the exterior of a VPX case for test through the transfer printed boards. Different transfer printed boards are connected with all signal test points. Radio frequency signals are transmitted to external test equipment through a radio frequency connector of the signal transfer board. The shell of the device is designed according to a Vita standard sub board module, and can be flexibly inserted into the VPX case. The VPX digital signal test device has the advantages of no need to disassemble the case, flexible and convenient test, high versatility, cost saving, and higher efficiency.

Description

technical field [0001] The invention relates to the technical field of VPX cabinets, an external device for detecting digital signals of VPX cabinets, in particular to a VPX digital signal testing device. Background technique [0002] VPX chassis has high-speed data acquisition, real-time signal processing and large-capacity storage functions, and has the characteristics of solid size, anti-interference, and vibration resistance. The usage of VPX chassis in the field of information and communication is increasing. Since the VPX chassis is connected by each sub-board to the backplane to complete the transmission and processing of various signals, in order to judge the characteristics of the connection signals between the backplane and the sub-board, it is necessary to configure a test fixture. The test fixtures for testing VPX signals in the prior art are all single customized printed boards. The problem is that the user needs to remove the backplane or sub-board module from ...
