Automatic signal testing method, device and system

Abstract

The embodiment of the invention provides an automatic signal testing method, device and system, and belongs to the technical field of electronic product testing. The problem that manual testing is needed for existing signal testing is solved, automation of the signal testing is achieved, application range of the signal testing is enlarged, and repeatability of the signal testing is enhanced. Meanwhile, work efficiency is greatly improved. The method includes the steps that test instruction information sent by a user is received; a schematic diagram of a tested single plate where the tested signal is located and a pcb document of a printed circuit board are obtained according to the received test induction information; a test template is selected according to the schematic diagram of the tested single plate where the tested signal is located and the pcb document; a test node is selected from the test template according to the received instruction information of selecting the test node; based on the test node and the test template, test signals are obtained through a test probe; the test signals are analyzed to obtain test data and a test pattern. The automatic signal testing method, device and system are applied to signal testing.

Description

technical field

[0001] The invention relates to the technical field of electronic product testing, in particular to an automatic signal testing method, device and system. Background technique

[0002] In the development and production process of modern electronic products, various tests need to be carried out on the products, which are generally divided into three types: functional test, performance test and signal test. Among them, functional testing and performance testing are also called "black box testing", and the test results are discrete values, a set of arrays or judgment results, so they can also be called "one-dimensional testing".

[0003] Signal test is also called "white box test". The test result is the result of the measured physical quantity changing with time or space and their mathematical operation process. According to the test result, two-dimensional or three-dimensional distribution matrix information can be obtained, so "white box "Test" can more clea...
