Convenient PXIe module debugging tool

Abstract

The invention discloses a convenient PXIe module debugging tool comprising a tool board card. One end of the tool board card is provided with first sockets capable of being docked with a PXIe case backboard socket. The other end of the tool board card is provided with second sockets capable of being docked with a PXIe module. The first sockets and the second sockets are connected in a one-to-one correspondence way so as to lead out all the signals of the case backboard. The beneficial effects of the convenient PXIe module debugging tool are that all the signals of the case backboard are led out through the tool board card without difference, the attenuation of the signals is controlled through the integrated circuit, the line width and the line length of the high-speed difference signals between the case backboard and the PXIe module are matched by the switch, the service life is prolonged by using the steel protection structure design, then the debugged PXIe module is inserted in thetool socket to be debugged and the signal of each position of the PXIe module can be clearly, rapidly, conveniently and accurately tested through the test instrument so that the module debugging timecan be shortened, the debugging efficiency can be enhanced and the development progress can be accelerated.

Description

technical field [0001] The invention relates to a convenient PXIe module debugging tool. Background technique [0002] At present, the PXIe system composed of PXIe modules has become the standard platform in the field of test and measurement due to its advantages in execution speed, test accuracy, and bandwidth performance. However, to build more types of PXIe systems, it is necessary to develop more types of PXIe module. At present, when debugging PXIe modules, because there is no ready-made debugging tool, the PXIe module to be debugged can only be directly inserted into the corresponding slot in the PXIe chassis, and then the module is powered on. If you want to test a test point signal in the module, you need to use Hold the test leads of multimeters, oscilloscopes and other test instruments and extend them into the chassis, touch the probes of the test leads to the test points of the PXIe module circuit board, and read the voltage, waveform and other data of test instr...

AI Technical Summary

Problems solved by technology

[0003] Directly insert the PXIe module to be debugged into the corresponding slot in the PXIe chassis for debugging without using the debugging tool. The disadvantage is that it is difficult to determine the position of the test point. When the circuit board needs to be tested, there are a lot of test point data. It is very inconvenient to insert the test leads into the narrow space in the chassis every time. The test efficiency is low and the test error is large, which seriously restricts the debugging progress of the PXIe module.
