Embedded computer electrometric integrated instrument

Abstract

The invention relates to an embedded computer electrometric integrated instrument comprising a control unit, an input circuit unit and an output circuit unit. The control unit comprises a main control processor, a memory and a human-computer interaction interface; the main control processor is respectively connected with and controls the memory and the human-computer interaction interface; the input circuit unit comprises input circuit functional modules of various functional instruments, such as an oscilloscope module, a spectrum analyzer module, a logic analyzer module, a multimeter module, an LCR measuring instrument module, a cymometer module and / or a digital integrated circuit tester module; the output circuit unit comprises a signal generator functional module; and the control unit is communicated with various modules of the input circuit unit by buses and controls the modules to work. The electronic measuring instrument realizes the functions of basic instruments for users, such as a signal generator, an oscilloscope, a logic analyzer, a spectrum analyzer, a cymometer, a digital integrated circuit tester, an LCR measuring instrument, a multimeter, and the like, and the functions of all the instruments can operate in parallel.

Description

technical field [0001] The invention relates to an electric variable testing device, in particular to an embedded computer electric measuring comprehensive instrument. Background technique [0002] Existing general-purpose electronic measuring instruments are mainly discrete instruments, with single functions, no embedded operating system, and no combined expansion functions, such as signal generators, oscilloscopes, logic analyzers, spectrum analyzers, frequency meters, and digital integrated circuit testers. , LCR measuring instrument, multimeter, etc. When in use, two or more instruments with different functions are often required at the same time, which brings inconvenience to users. Contents of the invention [0003] The main purpose of the present invention is to provide a kind of embedded computer electrical measurement integrated instrument, realize signal generation, oscilloscope, logic analysis, frequency spectrum analysis, frequency meter, digital integrated ci...
