What to Look for in an Oscilloscope

What to Look for Before Buying Oscilloscope

Before you take out your wallet, you have to keep some certain details you have to keep in mind. So, let’s take a look at these features.

Bandwidth

Let us reiterate; this is the most significant metric of an oscilloscope’s quality. Since bandwidth means it gives you a larger range of frequencies it can record, it essentially measures how accurately you can assess the waveforms from your inputs. So, bandwidth should be the first detail you note before you buy anything.

Sample Rate

Next, you’ll need to keep an eye out for how fast the machine can gather the data. Since you’re gathering more data faster, you’ll get much more detailed waveforms. They’ll also gather fast signals as well. So, do keep sample rates in mind as well.

Channel Number

When you’re working with bigger projects, you’ll need to analyze multiple signals at the same time. The more channels you have, the more waveforms you can analyze simultaneously. So, if that is important to you, you should consider it before you pick what to buy.

Memory

If you want precise analysis, you’ll need long streams of data. So, a good oscilloscope needs to have the memory to get you that data. As such, keep a note of their memory capacity.

Software and Other Features

Some units come with the relevant software to use with your PC for real-time analysis. These are extremely handy features to have.

There are a plethora of other features such as automatic measurements, interactive display, and intelligent trigger modes that have a massive effect on how you use the machine.

So, if you’re looking for the oscilloscope for automotive purposes, then you’ll need to see if the machine has relevant supplementary features.

Purpose

Keep in mind that there are a lot of purposes for an oscilloscope. For example, if you’re looking for the oscilloscope for audio, then you’ll need to see if your chosen unit can do so.

Main Characteristics of Oscilloscopes

You must understand the attributes you can expect from these machines. They are not the same. Some are meant for automobiles, while others are meant for laboratories.

Nevertheless, there are some universal characteristics that you must keep an eye out for. So, before we get down to the oscilloscope reviews, let’s have a look at these features.

Bandwidth Capacity

Whenever you want to buy a new oscilloscope, you’ll look at the bandwidth first. It is an indicator of the range at which the oscilloscope can accurately record information. The higher the bandwidth, the wider the range you can measure.

As such, it has a direct correlation with the capability of each unit. No matter what type of device you’re going for, the bandwidth is vital.

If you’re not sure if a device has enough of it, there is an easy rule to follow. Make sure it is five times higher than the maximum signal frequency.

If not, it can’t provide an accurate assessment of the wavelengths. Remember, the bandwidth is measured in megahertz (MHZ).

Sample Rate

The second most vital aspect of any oscilloscope is its sample rate. It is essentially the number of samples you can input into the device at a time.

So, a higher real-time sample rate means you can sample more of the input and render it into a comprehensible record.

As a result, more sample rate lets you record more volatile signals. Lower sample rates are also acceptable if your projects mostly focus on slow-changing frequency as opposed to fast-changing ones.

However, in a general sense, it is ideal for getting a device with a better sample rate than one without.

Since they can take more info, they offer the most accurate information. Usually, general oscilloscopes have a maximum sample rate of 1-2 GS/s. The rates only increase as quality does.

Vertical and Horizontal Sensitivity Range and Control

These devices output an easily understandable X-Y graph, where the vertical Y-axis represents the voltage level, and the horizontal X-axis represents the time base.

This ultimately creates a representation of the waveform calibrations of the devices. The range is how much the machine can represent within those graphs.

Control, on the other hand, refers to something else entirely. For vertical, the control refers to an option that allows you to calibrate the vertical deflection sensitivity.

This is handy if you’re dealing with a lot of varying ranges of the input amplitude. The horizontal sensitivity control refers to your ability to adjust external horizontal inputs.

Memory

These devices need to process and portray a ton of inputs. For long-running experiments, you might have to collect data for a long period.

However, if it is unable to store that data and relay it to you, you won’t get accurate results.

As such, memory is important. The more memory a device has, the more data it can store and show. As such, the memory unit is an integral part of an oscilloscope.

Number of Channels

If you want to work with these machines, it’s likely that measuring and evaluating one circuit point at a time isn’t enough.

That’s why these devices come with multiple channels that can help you compare and evaluate signal sources.

Each channel is differentiated, so the samples go to their rightful channel and record. Do note that using multiple channels can reduce your maximum sample rate.

Noise

Noise, in these terms, records to interruptions that muddle the reception of data. Poor oscilloscopes generate a high amount of noise, while the opposite is true for high-end units.

If you strive for accuracy, then a lower noise level is nothing short of vital to an oscilloscope’s creation and features.

FAQ’s of Oscilloscopes

oscilloscope frequently asked questions

Here we have some of the most commonly asked queries regarding oscilloscopes:

Do I need a good display?

If you want to assess the waveforms clearly from the machine, then yes.

Are 2 channels worth it?

It is if you don’t need to gather too many signals simultaneously.

How important is firmware update?

Very. Make sure you always keep your device up to date.

Can I update the firmware through USB?

Some units support USB updating. It is possible for those units.

Are they noisy?

Some are, some aren’t. It varies from unit to unit, but you can assume that larger devices are more likely to make more noise.

Conclusion

It took a while, but you’re now knowledgeable about everything you need to know about these devices. Keep the details in mind and consider them carefully. With enough care and consideration, you can buy the best oscilloscope for whatever work you’re doing. Once you do, analyze with finesse!
