Best Digital Oscilloscope

In this digital era, electronic appliances are getting digitalized as well. So is the case in oscilloscopes. Hobbyists or professionals- everyone prefers digital oscilloscopes nowadays to test electric devices instead of analog ones. But what do they do actually?

Digital o-scopes are the most needed equipment to measure the voltage changes by translating the electric signals into waveforms. Voltage Malfunction, meaning an abnormal voltage reading figures out by, an oscilloscope. And detect the problems ratio on the screen. That’s why no electronic labs can run without it. 

Choosing the best digital oscilloscopes could be a shaking session. Especially for those who lack sufficient scientific knowledge.

Buying Guidelines to Select the Best Digital Oscilloscope 

Buying the best digital oscilloscope is not everybody’s cup of tea without sound technical knowledge. Well, it’s not rocket science either. By asking some easy questions to yourself, you can easily narrow down the list. However, based on those answers, you should look for the following aspects while purchasing this high-performance electric equipment. Let’s dig into the deep!

Bandwidth: First and foremost, check the bandwidth limit and relate it to your requirements. Also, check whether it supports your exact voltage range or not.

Waveform Update Rate: Certainly, it’s one of the most avoided yet most important features. Your digital monitoring device should not take so long to update the screen. Otherwise, you will end up missing an important signal in an emergency situation. 

Input Channels: We would recommend having a dual-channel digital o-scope at an entry-level. It would be enough to conduct all the professional-grade activities as well. Having more than two channels will only add some extra cost at this point.

Sample Rate: Based on the sample rate, an o-scope is labeled as to how fast it captures the waveform frequency. So, always go for a higher sample rate to obtain a more reliable result. Because the faster your device will collect samples in a single period, the more detail you will be viewing on the display.

Accuracy: How accurately your oscillometer can count on the voltage frequency? A good quality digital scope must have at least 3%-5% accuracy to detect every single change in the signal strength. 

Memory Depth: Although this feature will cost you a little more, make sure your digital waveform monitor has a standard memory depth. Otherwise, it cannot capture signals at a high sample rate. 

Size and Cost: Like any other electronic device, a scope should also be bought considering its size and cost-effectiveness. Whether the features do justice to the investment or not should be judged. Also, do you want a giant size to use on a desktop? Or you prefer a hand-held size? So, the size does matter, you see!

How Do You Use a Digital Oscilloscope? 

New in the world of electronics? Have very little knowledge about running oscilloscopes? No worries. Follow the tutorial below and you will learn the basic steps of using a digital oscilloscope successfully. Over time, you will be a master of scopes with adequate practice. So, let’s start the journey!

Step 1: Read the user manual carefully and identify the basic controls like a probe, screen, volts/div, time/div, vertical and horizontal position, etc.

Step 2: Now it’s time for setting up the device. First, turn it on. You will see a flat lime hopefully. If not, then you need to disconnect it from the probe. A dual-channel scope will display the inputs in different colors. You need to turn the volts/div button counterclockwise and turn the vertical position control. In this way, there will be a flat line in the display and the device will be ready for reading new inputs 

Step 3: In this step, the oscilloscope needs a steady signal. Once you connect the probe tip to the signal source, the signal should be displayed on the screen. Remember, it might need some adjustments by both the vertical and horizontal scales. 

Notice whether the wave is rising or falling off the screen or not. If so, adjust the vertical position to place it rightly. Then try edge triggering to set it to a particular level where you will only see waveform rising edge once in every period.

At this point, scaling, positioning, triggering- this should be your circle to follow until you get the exact reading.

Step 4: Finally, it’s time to measure. Though it depends on how many measurement tools your scope has, most digital oscilloscopes study frequency, voltage, and amplitude. If you want to use all the measurement facilities your device offers, check the user manual thoroughly.

Some scopes offer you to save, print, and store waveforms and analyze them later. Most digital oscilloscopes are including this latest feature these days.

This is how you can make the best use of a digital scope to accurately measure any electric signal.

What Is a Digital Oscilloscope Used for?

As you know, a digital o-scope is used for monitoring electronic or wave signals. Basically, it detects voltage variation over time. Besides, the follow-up signals are measured by a digital sampling oscillograph. 

DC Voltage: Whether manually or automatically, most of the latest DSO measures DC voltage. 

Frequency: As an ideal waveform monitor, digital scopes are famous for accurate frequency measurement. When you need to analyze the frequency of any signal, use it and have an automatic measurement.

Sound: Surprisingly, a digital storage oscilloscope can study sound as well. Just use a transducer to turn the audio files into voltage and connect it to a scope. Then rest assured to have an exact volume of sound metering on the monitor. 

Current: A digital scope is capable of monitoring current by using a current probe. Or else, you can measure it by assessing the voltage drop ratio.

Capacitance: You can use it to count the capacitance of an electric system as well. Though no direct measurement will be there. 

By capturing momentary data like voltage deviation, constant time, and frequency, digital scopes analyze them and display results with authenticity. 

FAQ:

What is the advantage of the digital storage oscilloscope? 

The primary benefit of using a digital storage oscilloscope is to capture instantaneous waveforms accurately. Also, you can reserve the data for reviewing later. The high-speed digital signal processing system of this device collects complex signals and calculates them.

Which oscilloscope is used in a digital storage oscilloscope? 

As a high-performance electric device, a digital storage oscilloscope uses the conventional oscillometer to reduce the added cost. By using this, it digitally analyzes the inputs.

How does a digital storage oscilloscope work?

The functional mechanism of a digital storage oscilloscope depends on the digital memory and Cathode ray tube. Based on the three modes- roll, store, and hold, a DSO collects data and stores the waveform in the digital format. 

What is the difference between analog and digital oscilloscopes?

The basic difference lies in the measurement method. An analog oscilloscope displays the originally captured waveforms. But in the case of a digital scope, the input signals are converted digitally by an analog to digital converter and then displayed. Therefore, digital oscilloscopes offer more accuracy. Also, you can store digital information for as long as you want in a digital o-scope.

How many types of acquisition methods are there in a digital storage oscilloscope? 

You will find three types of acquisition methods in a DSO. Real-time sampling, random repetitive sampling, and sequential repetitive sampling are the three basics for digital oscilloscope acquisition control through which digital signals are captured and stored.

Final Verdict 

Nowadays, a digital o-scope is an essential must to run any electrical engineer’s lab. To determine the exact electric signals, no other device can replace an oscillograph. We have presented some of the best digital oscilloscopes before you to make your buying journey more interesting. Choose wisely based on your needs.

For example, you can opt for YEAPOOK if you need a cheap one. In this regard, ETEPON wins the race with an unbeatable price range. As a hobbyist, Hantek DSO5072P or YEAPOOK ADS1013D will be a perfect pick. Count on Siglent Technologies for their amazing all-purposes digital oscillometers.
