Abstract

The invention provides a novel nonlinear analog circuit fault diagnosis device. The novel nonlinear analog circuit fault diagnosis device comprises: a shell and a sealing plate; an oscilloscope main body, wherein two sides of the oscilloscope main body are fixed between two sides of the inner wall of the shell, and the front surface of the shell is movably connected with a cover plate; and a through hole, wherein the through hole is formed in the back surface of the shell, and a cooling fan is arranged in the through hole. According to the novel non-linear analog circuit fault diagnosis deviceprovided by the invention, the oscilloscope main body can be cooled by starting the cooling fan, and external dust can be prevented from entering the oscilloscope main body by arranging the dustproofcover, so that the service life of the oscilloscope main body is prolonged, and the cooling effect is prevented from being influenced by dust attached to the cooling fan; when the dustproof cover isblocked, the dustproof cover can be detached, cleaned or replaced, the operation steps are simple, only the second connecting rod needs to be pulled, and the detaching efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a novel nonlinear analog circuit fault diagnosis device. Background technique [0002] Analog circuits refer to circuits used to transmit, transform, process, amplify, measure and display analog signals. Analog signals are electrical signals that vary continuously. Analog circuits are the basis of electronic circuits, which mainly include amplifier circuits, signal calculation and processing circuits, oscillation circuits, modulation and demodulation circuits, and power supplies, etc., and nonlinearity in communication terms, that is, nonlinear modulation in analog modulation systems, Nonlinear modulation is also called angle modulation. The spectrum structure of the modulated signal is very different from the spectrum structure of the modulated signal. In addition to spectrum shifting, many new frequency components are added. [0003] When the existing non-linear analog circ...
