Abstract

The invention disclosed a multifunctional tester, comprising a digital storage oscilloscope module, a digital multimeter module, a function signal generator module and a frequency meter module, which is characterized in that, the control plate of the digital storage oscilloscope is used as the motherboard of the multifunctional tester, and is provided with a multi-computer communication module and a display calculation module which are used to communicate with the data of the digital multimeter module, the function signal generator module and the frequency meter module and display the calculation. The digital multimeter module, the function signal generator module and the frequency meter module acquire the input commands of users by the communication of the motherboard, interact the output data with the motherboard, and then display the output data by the display screen. The invention has the advantages that the invention provides a multifunctional tester covering the common electronic testing devices acquired by the field monitoring which is convenient for the electronic engineers to do common tests, and sets up a testing platform which is convenient for the electronic engineers to do common tests.

Description

technical field [0001] The invention belongs to the technical field of electronic measurement, and in particular relates to a multifunctional tester. Background technique [0002] In the prior art, the testing instruments commonly used by electronic engineers are: [0003] Digital oscilloscope: It is significantly different from traditional analog oscilloscopes and has unique advantages. At present, with the rapid development of science and technology, the capture, measurement and research of a single signal have attracted more and more attention and attention from people. Software, as well as occasional faults and soft faults caused by the joint action of software and hardware, are troubled by complex problems such as soft faults. A higher-speed DSO is urgently needed to solve these problems handily. [0004] Digital multimeter: The multimeter is definitely the most commonly used measurement tool in the field of electronic measurement. Electronic engineers can use the mul...
