Jig plate for testing signals of multifunctional vehicle bus (MVB) and wire train bus (WTB)

Abstract

The invention discloses a jig plate for testing signals of a multifunctional vehicle bus (MVB) and a wire train bus (WTB). A WTB connector, an MVB connector, a bayonet nut connector (BNC), a test circuit, rectangular connectors, a logic analyzer probe, a universal meter probe and a power supply connector are arranged in the plate; the MVB connector and the test circuit are in two-way connection with the first rectangular connector; the WTB connector is in two-way connection with the second rectangular connector; the BNC connector, the first rectangular connector and the second rectangular connector are in two-way connection with a matrix switch; and the universal meter probe and the power supply connector are in two-way connection with the first rectangular connector. By utilizing the jig plate, the problems that probe accessories and the like of instruments and meters cannot be reliably interconnected with a bus connector and test data cannot be acquired quickly, precisely and efficiently during test in the prior art are solved, the speed of routing of a test signal, the test efficiency and the test precision are improved; and the automatic test is realized.

Description

technical field [0001] The invention relates to an MVB and WTB signal test device, in particular to a MVB and WTB signal test fixture board. Background technique [0002] At present, instrumentation (such as oscilloscope, logic analyzer, multimeter and function signal generator, etc.) Not the same, because the measurement object is the MVB / WTB bus signal, the probe accessories of the instrument cannot be reliably interconnected with the bus connector, and the test data cannot be obtained quickly, accurately and efficiently during the test process. Oscilloscopes, logic analyzers, function signal generators, multimeters, and test power supplies are required for performance testing. If you manually operate a single instrument for measurement during the test, MVB / WTB bus signals are not easy to connect to the instrument, and the wiring is complicated. There are disadvantages such as difficult line switching, relatively large manual error and low test efficiency. Contents of t...

Problems solved by technology

[0002] At present, instruments and meters (such as oscilloscopes, logic analyzers, multimeters, and function signal generators, etc.) have various accessory interfaces (such as rectangular interfaces, SMA interfaces, BNC interfaces, and various accessory probes, etc.), and there are various ways to introduce signals into the instrument. Not the same, because the measurement object is the MVB / WTB bus signal, the probe accessories of the instrument cannot be reliably connected to the bus connector, and the test data cannot be obtained quickly, accurately and efficiently during the test process. Oscilloscopes, logic analyzers, function signal generators, multimeters and test power supplies are required for performance testing. If you manually operate a single instrument for measurement during the test, the MVB / WTB bus signal is not easy to connect to the instrument, and the wiring is complicated. Disadvantages such as difficult line switching, relatively large manual error and low test efficiency
