All About Analogue Oscilloscopes


Oscilloscopes, also known as scopes, are electronic test instrument devices that are used to measure voltage. Oscilloscopes are very significant devices for electricians. It can help their lives on so many levels. They are the most capable devices to understand what is wrong with an electronical system. Oscilloscopes are almost capable of solving every voltage related problem of electricians by itself.


There are different types of these amazing devices nowadays with varying capabilities. Electricians nowadays utilize digital oscilloscopes which is the most common type of oscilloscope today, easy to carry Portable oscilloscopes, very convenient to use USB oscilloscopes and more in a daily basis. However, before all of these fancy and capable oscilloscope types, there was one who made this all possible, Analogue Oscilloscopes.

What is Analogue Oscilloscope?


Analogue Oscilloscope is the predecessor to all the oscilloscope types. The first recorded use of oscilloscope dates back to first quarter of 20th century. Analogue Oscilloscope also known as Cathode-ray Oscilloscope paved the way for many advancements in the field of electricity.

Even though analogue oscilloscope seems somewhat outdated beside brand new digital and portable oscilloscopes, they can still measure voltages properly for an electrician any time of the day. Moreover, although they are almost over hundred years old, analogue oscilloscopes still has a faster reaction time than any mechanical measuring device.

What are the features of Analogue Oscilloscopes?


An analogue oscilloscope contains a cathode ray tube, a timebase, a horizontal amplifier, a vertical amplifier, and a power supply.

Since Analogue Oscilloscopes are the earliest type of oscilloscopes, their capabilities are somewhat overshadowed by the new types of oscilloscopes. Yet, Analogue Scopes have carried out their task of measuring signal voltages for years with success. So, every person working in the field of electricity know their value and acknowledge that analogue oscilloscopes carried their field to the next level.

Looking at the physical features of analogue oscilloscopes, it is easy to say they are heavy and static devices. They have a screen that displays the waveforms and a control panel to adjust the values.

What are the differences between Analogue and Digital Oscilloscopes?digital-oscilloscope-analog

There is an obvious technological era difference between analogue scopes and digital versions. This also accounts for the difference in size and portability of the two. Like most of the electronic devices, Oscilloscopes were also very heavy and hard to carry back in the day.

Besides the obvious physical differences between these two types, their capabilities differ as well. Digital Oscilloscopes have digital storage inside them for storing the previous measurements. Then digital scopes use these previous data to automatically analyze the newer ones. The digital storage also caused changes, in the form of new buttons, in the control panel of digital scopes.

Digital oscilloscopes have different versions that are easily carriable, which was never an option for Analogue ones. This aspect of digital oscilloscopes is so good for electricians working in the field.

These the two devices have many more differences considering one is almost 50+ year old than the other. However, you need to keep in mind that without the analogue oscilloscopes guiding the electricians through dark times, there would be no digital oscilloscope. So even though analogue oscilloscopes have lost their place as the most prominent type of scope, they will always be remembered as the first oscilloscope.

I’m doing research for a long time about this stuff. Finally, I found someting useful. Thanks a bunch for this great article. I’m waiting for more!

wojzniak v.

thanks for the insights esp. about the differences between the digital oscilloscopes and the analogue ones. Can you guys reach me?


Wow, finally i found my article that i want. Thank you soooo much. Its very helpfully!


I have always wondered about oscilloscopes. It was a very useful article. Thanks!
