Embodiment Construction

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that although similar components appear in different drawings, they are given similar reference numerals. In addition, in the following description, when detailed descriptions of known functions and designs adopted may dilute the subject matter of the present invention, these descriptions will be omitted here.

[0016] figure 1 It is a functional block diagram of a specific implementation of a communication design between various modules in the multifunctional tester of the present invention. In the picture, all the modules use the same keyboard and LCD display. The keyboard and LCD display are connected to the control board 1 of the digital storage oscilloscope module, which is the main board of the multi-function tester. The remaining three tester modules are digital multimeters. Module 4, function signal generator module 5 and frequ...

Abstract

The invention discloses a multifunctional tester, which comprises a digital storage oscilloscope module, a digital multimeter module, a function signal generator module and a frequency meter module, and is characterized in that the control board in the digital storage oscilloscope module is used as the main board of the multifunctional tester , there are multi-computer communication modules and display calculation modules on it, which are used for data communication and display calculation with the digital multimeter module, function signal generator module and frequency meter module. The digital multimeter module, function signal generator module and frequency meter module pass through The main board communicates to obtain user input commands, and then interacts the output data with the main board to display the output data through the display screen. Thus, a multifunctional tester that is convenient for routine testing and covers common electronic testing instruments required for on-site monitoring is provided for electronic engineers, and a testing platform for routine testing is established for electronic engineers.

Description

Technical field [0001] The invention belongs to the technical field of electronic measurement, and specifically relates to a multifunctional tester. Background technique [0002] In the prior art, the test instruments commonly used by electronic engineers include: [0003] Digital oscilloscope: It is significantly different from the traditional analog oscilloscope and has unique advantages. At present, with the rapid development of science and technology, the capture, measurement and research of single signals have attracted more and more attention and attention. In the field of information, high-speed computers, high-speed data communications, and high-speed digital integrated circuits and their systems, they are faced with hardware, The software, as well as the sporadic failures and soft failures caused by the joint action of software and hardware, is an urgent need for a higher-speed DSO to solve these problems handily. [0004] Digital multimeter: The multimeter is definitely...
