Handheld intelligent signal generator

Abstract

A handheld intelligent signal generator structurally consists of a light touch switch circuit A, a central processing unit B, a reset circuit C, a crystal oscillator circuit D, a matrix key circuit E, a nixie tube display circuit F, a D / A (digital / analogue) conversion and amplification circuit G and a power and current protection and output circuit H, wherein the central processing unit B, the D / A conversion and amplification circuit F, and the power and current protection and output circuit H form a main circuit, the nixie tube display circuit G provides a digital readout function, and the reset circuit C and the crystal oscillator circuit D provide necessary support for a singlechip processing unit F. The handheld intelligent signal generator has the advantages of simplicity in operation, multifunction, small and exquisite volume, reasonable structure, convenience in carrying and suitability for one-hand operation, thereby meeting requirements of various laboratorial and industrial site instruments for debugging, detection maintenance and verification.

Description

Technical field: [0001] The invention provides a digital-display, intelligent industrial meter calibrator, in particular a hand-held intelligent signal generator. Background technique: [0002] Although there are many types of signal generators in the prior art, the common shortcomings in use are that the circuit design is unreasonable, the shape is too large, and the use of AC power supply is mainly reflected in the fact that the traditional signal generator is a desktop design, and the volume is too large. When used for on-site debugging, calibration or inspection and maintenance of industrial instruments and automatic control systems, it is difficult to carry, and it is extremely inconvenient to use AC power supply on the power supply, and it lacks voltage and current overload protection, so there is a problem with the signal generator. The use effect and service life have a great influence. Invention content: [0003] The purpose of the present invention is mainly to ...
