Automatic test system and test method for digital measuring instrument

Abstract

The invention discloses an automatic testing system and an automatic testing method for digital measuring instruments. The automatic testing system comprises a testing host, the to-be-measured instruments and at least one standard instrument, wherein the to-be-measured instruments and the standard instruments are connected with the testing host, and the testing host is configured with a test program. The test program comprises a user interaction module and more than two testing modules connected with the user interaction module, the user interaction module is used for man-machine interaction between the testing system and a tester, man-machine interaction involves test case generation and importing, historical test case query and testing result check, and every testing module is connected with one to-be-measured instrument or standard instrument. The automatic testing system has the advantages that the automatic testing system is capable of achieving multi-combined automatic testing of the to-be-measured instruments and the standard instruments according to different testing environments by editing test cases through plain texts, so that testing environment setup is reduced, testing environment reusability is improved and an automatic testing applicable range is widened.

Description

technical field [0001] The invention relates to the technical field of automatic testing of digital measuring instruments, in particular to an automatic testing system and a testing method for digital measuring instruments. Background technique [0002] Automated testing is to run the automated test program containing test cases on the PC. The program configures the tested instrument and its auxiliary test instruments through multiple control links, reads data, controls the test system to send and receive test frames, and completes the test. The automatic acquisition and judgment of the results are repeated in this way, and finally the test results of the tested instrument are obtained. [0003] In the process of developing digital measuring instruments such as oscilloscopes, signal generators, and multimeters, some test indicators such as functionality and accuracy need to be continuously updated with product versions, and these indicators also require a large number of rep...

AI Technical Summary

Problems solved by technology

[0004] Common automated test systems need to establish a corresponding test environment for different functions of the tested instrument. Different tested instruments need a separate set of test environments and develop different automated test programs. In this case, the implementation of automated testing Higher cost and overhead

At the same time, common automated test systems require strong programming skills for writing test cases, which requires a relatively large investment of time and energy.
