Best Aliexpress Oscilloscopes

by Tollo Francis

An oscilloscope is a versatile electronic instrument that can be used for a range of critical measurements. These instruments are also known as o-scopes in short. Oscilloscopes come in a range of sizes, shapes, and prices. When trying to find the best oscilloscope for your lab, it is important for you to look at the features that they come with. Are you feeling too lazy to check out from a huge list? I have done the research for you and put together a list of the best oscilloscopes from my favorite eCommerce site – AliExpress. In AliExpress, you will find a huge collection of excellent oscilloscopes at affordable rates. Continue reading for an exciting journey.

What are oscilloscopes used for?

Oscilloscopes are instruments that are mainly used for graphing an electric signal as it varies over time. Most of the oscilloscopes that we get produce a two-dimensional graph that lets you do a number of things. With this device, you can see how electric signals change over time. These devices are used in the medical industry for various measurements. Doctors use this instrument to monitor brain activity through EEG, muscle activity through EMG, and the heart through ECG.

How does an oscilloscope work?

An oscilloscope looks like a TV from the golden days. A traditional oscilloscope also works almost the same way as the traditional Cathode Rat TVs that we had as kids. In a TV, electric beams hit the back of the screen that is coated with a special chemical called phosphor. When the beam hits it, it lightens up to form a picture. You do not realize the time intervals that go in between, and we are hit back with pictures on the screen. This process keeps repeating itself again and again, and so we see the pictures moving on our TV screen.

An oscilloscope works in a similar fashion, but instead of pictures, it draws wave shapes. When the circuit in an oscilloscope senses any sort of electron movement, it does two things. It measures the path of the electrons and the intervals between them. This process takes place at a lightning speed.

What should you look for in an oscilloscope?

There are several things that you need to consider before you make your choice. Here are some things that you must check out before buying an oscilloscope:

  • Analog or Digital
  • Bandwidth
  • Sample rate
  • Memory depth
  • Resolution
  • Accuracy
  • Triggering capabilities
  • Input ranges and probes
  • Form factor

Consider all of these factors before you finally make your choice.

What bandwidth should you choose for your oscilloscope?

You should choose an oscilloscope with a bandwidth that is at least five times higher than that of the fastest digital clock rate in your system under test.

What is the main advantage of an oscilloscope?

Unlike other devices, an oscilloscope gives you real-time reading. You get the right reading as soon as you connect your oscilloscope to a power source. Other devices only give you voltage readings.
