What is Analog Oscilloscope?


Oscilloscopes are devices used in measuring changes in an electrical voltage over a certain duration. Oscilloscope is one of the most fundamental and common device in the Electric Industry. There are different types of oscilloscope all of which have their own use. Being one of those types, Analog oscilloscope is the prime example of this device. Moreover, it is the easiest oscilloscope to use.

In this article, we will take a closer look at the analog oscilloscope: What are the pros and cons of the analog oscilloscope? What is the difference between Analog oscilloscope and the other types of oscilloscope? What are the use cases of an analog oscilloscope? You will find the answers to all these questions and more in this article.


History of the Analog Oscilloscope in a Nutshell

As we stated before, Analog oscilloscopes are the earliest type of oscilloscopes. In other words, they are the forefathers of all other types. Analog oscilloscopes were also called “ray oscilloscopes” back in the day. The reason behind this alternative naming was the cathode ray tube, an essential component of Analog oscilloscopes.


Uses of Analog Oscilloscopes in Today’s World

Although all the history we mentioned about Analog oscilloscopes might make them seem like they are somewhat outdated, that is definitely not the case. Analog oscilloscopes are still widely used all around the globe. It is also true that in recent years electricians prefer digital oscilloscopes to analog ones. However, there is still much use for them in our lives. Digital oscilloscopes are a little bit more expensive than their analog counterparts. Therefore, even in 2020, there are so many analog oscilloscopes around us. From colleges to middle schools, analog oscilloscopes are hugely used in education in order to welcome young students into the world of electricity.

Pros and Cons of Analog Oscilloscopes

One of the most prominent benefits of preferring the analog oscilloscope over a digital one is the affordable price. Analog oscilloscopes are considerably more affordable. That is why most educational institutes, schools and universities prefer analog oscilloscopes.

A considerable disadvantage of the analog oscilloscopes is their fragility. In a setting like a classroom, it is not easy to break or damage an analog oscilloscope. However, if you will need to move your oscilloscope often, analog is not a good option for you. 

The Difference Between Analog Oscilloscopes and Digital Oscilloscopes

The major difference between analog oscilloscopes and digital oscilloscopes is their capability. Analog oscilloscopes can measure and present a waveform in their original form. Meanwhile digital oscilloscopes can be used for much more bigger measurements with the help of the Analog-to-Digital Converter. Digital oscilloscopes basically take original waveform, sample it and then finally turn it into numbers.

Overall, although the emergence of the digital oscilloscopes changed the game considerably, analog oscilloscopes still withhold their place in our daily lives. Compared to their digital counterparts, they are much more accessible because of their competitive prices. They are classical devices which still can successfully perform many tasks. That is why analog oscilloscopes will be around for a long time.
