oscilloscope

  Oscilloscope is one of the most useful test tools used for designing electronic circuits, manufacturing electronic components, testing, servicing and repairing.

An oscilloscope is a test instrument that displays a voltage waveform as it changes over time. After the multimeter, it is probably the tool that most people who work with electronic circuits own in one form or another. Oscilloscopes are an important tool in the electronics engineer's or tester's arsenal. An oscilloscope is a piece of electronic test equipment that allows you to see waveforms, making it much easier to see any problems that occur in an electronic circuit.

Due to their advantages, oscilloscopes are an essential piece of electronic test equipment for any electronics lab or electronic hardware testing area, whether in general electronic circuit design, electronics manufacturing, service, repair, or anywhere electronic circuits and ... the waveform on them should be checked.

The name oscilloscope is because it allows the observation of oscillations. Sometimes the name cathode ray oscilloscope was used. The reason for this was that cathode ray tubes were used to display waveforms. Today, of these testing tools only to

It is called an oscilloscope or just a scope.


Types of oscilloscopes

In general, there are two types of oscilloscopes: analog and digital. The controls of both types are basically the same. Note that the digital range may hide some of the controls in the LCD display menu instead of using the button. The first types of oscilloscopes were analog, but with the advancement of digital technology, almost all new test instruments today are processor-controlled and use digital signal processing to provide excellent waveform displays.

Not only are oscilloscopes available in standard boxes, but some scopes are designed to connect to computers and use their display and processing to assist. Most are USB oscilloscopes that connect via USB links, but other types are available via other bus systems or for use in rack systems such as PXI and older VXI systems.


Oscilloscope application

Although oscilloscopes are easy to use these days, it helps to understand how these items of electronic test equipment work and what controls they have and how they work. There are even on-screen softkeys, so a lot can be done. Usually the most used controls are common to all domains from any manufacturer, so moving from one domain to another is often relatively easy.

Every oscilloscope requires a probe to connect to the unit under test. The performance and use of these scope probes make the best of real test instruments, so knowing which probes to choose, how to set them up, and the limitations is essential to truly understanding the measurements being made.


Oscilloscope components

Screen The first thing you notice in an oscilloscope is the large screen used to display the waveform. This may typically take up about a quarter of the front panel space or even a bit more. It's often good to have a fairly large screen, so it's easier to see the different elements of the waveform.

There are different types of connectors on the front panel. There is usually one entry for each of the channels to be displayed. Often an oscilloscope has more than one channel. Many oscilloscopes are dual-channel, so they can display two signals at the same time and allow comparison of waveforms. Other inputs may include a trigger input that activates the trace on the oscilloscope based on this signal.


Oscilloscope training

Oscilloscopes are useful for seeing very fast changes in voltage over time, things we couldn't measure with a multimeter. Usually, when you measure with an oscilloscope, you see a line running from one side of the screen to the other. This line is actually a plot of voltage versus time, where voltage is measured along the y-axis and time along the x-axis. When you connect to your signal, you should see the flat line turn into some kind of waveform.

Adjust your timing so that you can see the separation between the oscillations, adjust the voltage and vertical position so that the waveform oscillates within the limits of the plate. The wave may be barely visible. If it doesn't, turn the trigger level switch until it does, you'll see a trigger level indicator move up and down the screen as you turn the trigger level knob.

Note that when the trigger level exceeds the height of the waveform, the signal becomes unstable. A trigger level is essentially a voltage level that your oscilloscope compares the incoming signal to, allowing it to stabilize a repeating waveform or record voltage spikes on the screen. Setup can be quite complex, there are cases where people use external trigger sources and specify specific trigger modes. However, for most applications you will find that this is not necessary, and simply setting the trigger level to some voltage within the range of your input signal is sufficient.
