Problems solved by technology

[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 meter, multimeter, etc., only one specific function
However, in actual field applications, two or more instruments with different functions are often used at the same time. Users need to carry a variety of instruments when they work. Many instruments, large volume, and relatively heavy, all bring inconvenience to users

Abstract

The invention provides an electronic test comprehensive instrument, which comprises a casing with a cuboid structure, and oscilloscope interfaces and signal source interfaces which are disposed on oneside wall of the casing. A USB data communication interface, a USB indication lamp, a configuration switch button, a multimeter voltage/resistance test port, a multimeter common test port, a multimeter current test port, a power indication lamp and a USB power supply interface are arranged in sequence on the other symmetrical side wall. The upper surface of the casing is provided with two sets ofpin headers, and the casing is provided with a MCU controller, a power module, A/D sampling modules, and DA converters. The invention also provides an electronic test comprehensive instrument and anoperation method thereof. The invention realizes the functions of an oscilloscope, a signal generator, a power source, an amplitude frequency characteristic analyzer, a spectrum analyzer, and a multimeter, can simultaneously use multiple function modes, and not only has full functions, but can further develop a new functional module. The instrument is small, lightweight and portable, and is a newpocket instrument.

Description

technical field [0001] The invention relates to the technical field of electronic testing, in particular to an electronic testing comprehensive instrument and an operating method thereof. 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 meter, multimeter, etc., only one specific function. However, in actual on-site applications, two or more instruments with different functions are often used at the same time. Users need to carry multiple instruments during work. There are many instruments, large volume, and relatively heavy, which bring inconvenience to users. Therefore, it is imperative to develop a small and portable electronic test comprehensive instrument that integrates...
