One of the devices frequently used in the electronics industry is the oscilloscope. Why is an oscilloscope needed in electronics repair? How are electronics tested using an oscilloscope? What is the most valuable oscilloscope for electronics? Let's examine the use of oscilloscope in electronics together. 

Why Do You Need an Oscilloscope For Electronics Repair?

As important as the heart rate monitor for people, the oscilloscope is as important for electronic repairs. The life of our devices can be voltage or current. We do not want our hearts to beat too fast or too slow, we want these voltages to be released at the correct speed or frequency. It is quite logical to use an electronics oscilloscope as we do not want any malfunction in our electrical signals. Obtaining such information about your electronic devices allows you to verify that it works as expected. And if not, oscilloscopes will help you diagnose and fix the problem. Whether you are an electrical engineer, test engineer, or student, you can use an electronics oscilloscope or work with an oscilloscope for production, repair, research or development.

How Do You Test Electronics Using an Oscilloscope?

The electronics oscilloscope allows you to double check that your device's signal is what you expect, both in size and frequency. As it provides a visual representation of the signal, you can see abnormalities or distortions that may occur. However, there are some things you should consider before starting the test. These are as follows.

 

  • Bandwidth:

    It is the frequency range that the oscilloscope can accurately measure. Oscilloscope bandwidths typically range from 50 MHz to 100 GHz. 
  • Sampling Rate:

    The number of samples the oscilloscope can obtain per second. As the number of samples per second increases, the waveform is displayed more clearly and accurately. 
  • Signal Integrity:

    The ability of the oscilloscope to accurately represent the waveform. You don't want to spend weeks trying to declare your device to be faulty and find the root cause when it's actually not a problem. Therefore, signal integrity is an important feature. 
  • Channels:

    It is the entrance of the electronics oscilloscope. They can be analog or digital. There are typically 2 to 4 analog channels per oscilloscope. 
  • Probe Compatibility:

    The probe is the tool used to connect the electronics oscilloscope to your tested device. There are a wide variety of passive and active probes, each made for special use cases. It is very important to find an oscilloscope compatible with the type of probe you need for your specific tests. 
  • Applications:

    Signal analysis, protocol decoding and compatibility testing software can greatly reduce the time required to identify and catch errors in your designs. Analysis software can help you find and evaluate vibration, create eye diagrams, and even define and measure crosstalk.

After all these settings are made, the connection between the electronics oscilloscope and the device is established. The oscilloscope, which is also connected to a display device, displays the signals of the electronic device. In this way, the signals are measured. If a malfunction is detected in the signals, repair work begins.

For this reason, the oscilloscope is a very important device in the maintenance and repair of electronic devices. For example; In the electronics repair such as digital clocks, an oscilloscope is used in operations such as monitoring the signal on the crystal ends, observing the signal on the processor outputs and understanding the signal in the driver's integration. 

Best Value Oscilloscope for Electronics

When it comes to using an oscilloscope in electronics, a physical proximity is required. There are several different types of oscilloscope. All of these types can be used in electronic circuits. Variations of the oscilloscope are as follows. 

Analog Oscilloscope:

The analog oscilloscope, which has the same working principle as tube televisions, has a principle that the electron beam occurring in the cathode ray tube is formed by the image that is applied to the phosphor screen by the input signal applied to the vertical and horizontal deflector coils. 

Digital Oscilloscope:

The digital oscilloscope, which is preferred more frequently than analog models, has the ability to transmit incoming signals with a faster and accurate result thanks to its advanced microprocessors. 

USB Oscilloscope:

USB oscilloscopes, which are more affordable than other types of oscilloscopes, do not have a screen on them, so a computer is definitely needed. 

Handheld Oscilloscope:

It is preferred because of the size of the hand-held, that is, portable, oscilloscope, because of its small size and being portable. Handheld oscilloscopes that can be used with battery or by charging are high accuracy devices. It is often used in field studies. 

Although it varies according to the electronic device and the conditions of the environment, it can be used for all types of electronics oscilloscope
