What districts are there when ondoscope and logic analyzer are testing signal circuit

Posted on May 24, 2013 by admin

The friend who uses the ondoscope should all know, the ondoscope has vertical resolution of great, can be sharp saw corrugate detail. And it have dog days / dose and second /assist us not to be understood dose,etc. turn button by waveformed observed that we needed better going. And the intersection of logic analyzer and 1 vertical resolution only, judge measured signal still ‘ 1 ‘ as logical value ‘ 0 ‘ according to threshold presumed. Sequence and state relation of the multiple paths that logic analyzer pays close attention to even more.

There are less numbers of channels of simulation of the ondoscope, there can generally be No. 2 to the passways of No. 4; And the logic analyzer can have a large number of digital channels to link with tested subject, can reach dozens of more than one hundred passways.

Two kinds of advantages that compatible that there are some ondoscopes in Tyke Company, for example: MSO4000 ondoscope has advantage of the two, there are analog channels that observe circuit-under-test detailed information, analog channels of No. 16 link with circuit-under-test. And the simple operation of extending the ondoscope on Read more

Ondoscope, since appearance, it most important, most frequently used electronic instrument one of. Because the technical development of electron, the ability of the ondoscope is promoting constantly, its characteristic and price are multifarious, the market is different. It is simple for ondoscope to seem to be, but how about choose, there are a lot of problems too. The experience for many years of the foundation of this text, combine marine industrial Science Technologies Co., Ltd. lectotype guide in Beijing, tell the question that you should pay attention to from several respects while choosing an ondoscope:

First, signal understanding you need to test

Do you want to know what is observed with the ondoscope? What is its typical characteristic of signal to be caught and observed of yours? Does your signal have a complicated characteristic? Is your signal a repetitive signal or single signal? You want the bandwidth of the metric signal transition transient, or how big is the duration of ascent? With which kind of signal characteristic do you plan to touch off burst pulse, impulse width, narrow pulse,etc.? How many signals do you plan to reveal at the same time? Read more

As the micromation intensity is improved constantly, component and routing technology obtain enormous development, such as miniature IC of the encapsulated high integration density of BGA outer cover, and the insulating interval between the conductors is lessened to 0.5mm, these are two examples among them. The design of routing of the electronic element, could well go on to the test in the production process, influence greater and greater. Now introduce several kinds of important rule and practical suggestion.

Through observing certain rules DFT-Design for Testability, testable design ,Can reduce preparation and implementation expenses of production test greatly. These rules have already passed and developed for many years, certainly, if adopt new production technology and component technology, they want corresponding expansion and adaptation too. As physical dimension of electronic product being smaller and smaller, two very noticeable problems have appeared at present: First, there are fewer and fewer nodes of electric circuit that can be contacted; Second, look like the on-line test In-Circuit-Test The application of these methods is limited. In order to solve these Read more

Though present server and PC favor the advanced high-speed processor more and more, but 20 low-grade or 30MHz processor is also contributing in actual life. Though these clumsy microprocessors are outmoded in design, history for many years, but they still occupy a tiny space in machinery, consumption electron and car current consumer.

Embedded processor these and what common points does it employ, have? Summing up has such several obvious characteristics: First, this kind of processor fully proves through a lot of products, people all understand very much, and developing can get extensive support, it is apt to design; Second, compared with existing advanced scheme, its clock rate is relatively slow, the speed of bus line is very slow too; Third, application system from selling the beverage-making machine to the avionic equipment automatically There must be very high reliability; Finally, cost including the design, manufacture and maintenance charge It must be low as much as possible.

There is a noteworthy characteristic, namely there is such a stable development trend at present, these embedded device and bus line clock rate are all improving constantly, it is Read more

1. Foreword

The detection technique is that a door employs very extensive technology. Will measure various jobs, various bodies in motion in a lot of fields, in order to guarantee the qualification rate of the products and safety produced, lived. The traditional detecting means is measured manually, useful mechanical type, optical or detection that the magnetic detecting instrument of electricity carried on too. Especially measure all according to actual working experience manually, if the block construction is complicated, not only has increased workers’ labor intensity, but also precision, efficiency will be thereupon reducing, not only it is not the rub check not to finish but also can’t realize on-line testing, increased the danger brought to staff member’s institute while measuring yet at the same time. So, with the change of science and technology, there certainly will be a kind of perfect detection technique, that is CCD technology. Here, with an embodiment based on that it is not rub check that CCD is online – -” draw high the intersection of wire rope and diametral online detector ” go on the discussion to CCD technology.

About ondoscope

The ondoscope is used for measuring the instrument of the shape of the alternating current or impulse current wave, made up of vacuum tube amplifier, sweep oscillator, cathode ray tube,etc.. Besides observing the waveform of the electric current, can also determine frequency, voltage strength,etc.. The periodic physics can turn into electrical effect ing can all be observed with the ondoscope.

The ondoscope is divided into digital oscilloscope and analog oscilloscope. What the analog oscilloscope is adopted is analogous circuit oscilloscope tube, its foundation is an electron gun The electron gun is to the emission of electrons of the screen, the emissive electron is focused on and forms the electron beam, and hit on the screen. The interior surface of the screen coats with the fluorescent material, in this way the point that the electron beam hits will emit the light. But the digital oscilloscope is the data acquisition, A/D changes, the high-performance ondoscope which a series of technology such as the programming of software make out. The digital oscilloscope generally supports the multiple menu, can offer many kinds of choice to users, Read more

Analog oscilloscope operation method

The analog type ondoscope reveals waveform and waveform stable principle
Reveal the undulate principle:
As the measured signal connects the Y-axis deflecting plate that the indication ondoscope Y-axis is the oscilloscope tube, such as the sinusoidal voltage, if the X-axis is not handed in
Turn into the signal, function as sine type upper and lower back-and-forth movements with time from the electron gun emitted electron beam in the vertical direction, it is high-frequency to be general, the reality seen is a straight line. If the same pluses the alternation signal only on the X-axis, that was seen is only a level
Bright line. The ondoscope is built-in all have a sawtooth wave signal voltage generator, function of it to can offer, add in X-axis while being special, from low to high to directly proportional to changing with sawtooth voltage, make electron beam from left to right in the intersection of level and square even sport, then vary with the the signal one at once getting back to on the left, begin another uniform motion from left to Right deviation, is called scanning sports, the corresponding one is called the Read more

I2C bus bar is in the electronic product, a kind of very common bus bars, its advantage is to only need two striplines, control on can connect a lot of IC in parallel ing. But because of many devices Device And open a way and collect it very much Open drain Framework,it is if you can’t converge, exclude from by mistake to if you can’t work, difficult not to last I2C. This text will propose some actual application cases, and use the logic analyzer Logic Analyzer Its every function, come to assist to get rid of the question.

The materials are noted down to use the operation type to store and go on for a long time

When I2C bus bar signal happens unusually, the ones that often can’t be defined know which device makes mistakes. So, unable by presuming the way to touch off to do the alignment that click of the question. The user will most likely consider that pick up back all waveforms analysis slowly first. But the logic analyzer basically picks up the signal in a manner to sample, whether the signal has changed, will all be with sampling and picking up the going on of movements, and is consuming the memory body constantly. And the operation type Read more
