Description
Technical field
The present invention relates to electronic measuring technology field, particularly relate to a kind of oscillograph with memory function.
Background technology
Oscillograph is a kind of purposes electronic measuring instrument very widely, and it can become invisible converting electrical signal people can observable image, and being convenient to the change procedure that people study various electrical phenomena, is indispensable equipment during Electronics Engineer works.
Existing oscillograph can be divided into analog oscilloscope and digital oscilloscope.What analog oscilloscope adopted is mimic channel electron gun is to screen emissions electronics, and ejected electron line focus forms electron beam, and gets on screen, and the inside surface of screen scribbles fluorescent material, and the point that such electron beam hits will send light.Analog oscilloscope effect when showing high-frequency signal is the truest, best, but display low frequency signal ability is more weak, is limited by the bottleneck of bandwidth in addition, is replaced gradually by digital oscilloscope.Digital oscilloscope is data acquisition, and A/D changes, the produced high-performance oscillograph of a series of technology such as software programming.Display effect not as analog oscilloscope, but is with roomy, and feature richness, has become the main flow of test.
But, oscillograph in the market, cost is too high, or volume is comparatively large, and it is not very convenient to use, and existing oscillograph is if HH4310A/HH4311A, RS8 etc. are all without memory function, in engineering practice, there is single pulse signal a large amount of non-periodic, the appearing and subsiding of these signals is all paroxysmal, complete in the moment of Millisecond, delicate level or even nanosecond, engineering staff has little time observation signal at all and just disappears.
Summary of the invention
Based on the technical matters that background technology exists, the present invention proposes a kind of oscillograph with memory function, can storage pulse signal so that wave recurrence, and volume is little, easy to use.
A kind of oscillograph with memory function that the present invention proposes, is characterized in that, comprising: control treatment module, operational module, display module, memory module, A/D modular converter, signal input module and filtration module;
Control treatment module is attended operation module, display module, memory module, A/D modular converter and filtration module respectively, and signal input module is for accessing measured signal and connecting A/D modular converter and filtration module respectively;
In working order, by operational module, oscillograph is arranged; Signal input module is divided into two-way to be sent to A/D modular converter and filtration module respectively after receiving measured signal; A/D modular converter is sent to control treatment module after the signal received is converted to digital signal, filtration module is sent to control treatment module after the signal received is carried out low-pass filtering, is sent to display module respectively and memory module carries out image display and signal storage after control treatment module processes to the received signal; Control treatment module can be obtained the signal that stores in memory module and be shown by display module.
Preferably, filtration module adopts low-pass filter circuit.
Preferably, control treatment module adopts STM32 series processors.
Preferably, control treatment module adopts ARM9 processor.
Preferably, A/D modular converter adopts MAX118 chip
Preferably, display module adopts touching display screen.
In the present invention, oscillograph stores the signal collected, and wave recurrence can be carried out to the signal stored, solve non-periodic single pulse signal and occur instantaneously disappearing and cause engineering staff to have little time the problem of observing at all, be conducive to improving oscillograph performance and the scope of application.
Portable oscilloscope integrated level provided by the invention is high, is conducive to reducing volume and reducing power consumption.
In the present invention, operator is arranged oscillograph by operational module, to improve oscillograph operation flexibility, and can adjust oscillograph mode of operation according to operative scenario, to expand the scope of application.
