The Buyer’s Guide

USB vs digital device

This is going to be a major part of the choice. DSOs with their displays look pretty cool. They still eliminate the need to link to the PC, but they still sacrifice accessibility. USB o-copes are much easier, but if you just dip your toes into a hobby and don’t really know if you’re going to need a ton to warrant the additional expense, then it’s certainly worth going for a USB model.

Trigger modes

It involves triggering and getting the job of initiating a test. You may verify from this parameter what triggers the scan to start, or also whether there are any abnormalities. There are three simple trigger settings for each oscilloscope. Single: the scan takes place just once and thus at the first cause event. You need to click the right button to enable recovery to wait for another one.

Typically, there are 2 major trigger modes you may find in USB oscilloscopes:

  • Automatic – the scan restarts without the trigger;
  • Normal mode starts when the scan is triggered directly;

The sampling rate

It is the regularity of which the waveform components are seen by the o-scope. It determines how informative the details you will see will be, and how precise the information will be interpreted by the o-scope.

Similar to the camera’s frame rate, the larger the sample rate, the more accurate the data would be, enabling you to record even the slightest shifts in the waveform.

But, when you’re searching for an o-scope, make sure to consider the sampling rate, from the lowest sampling rate to the limit.

Although a high sampling rate has its advantages, a minimum sampling rate must also be known, in case you need to examine signals that are steadily evolving over a long period of time.

And as a side tip, you should use the rule of five to guarantee that the oscilloscope sampling rate is at least 5 times that of the peak frequency of the project you’re focusing on.

Bandwidth

Depending on the form of use for your scope, you will need to keep a close eye on the bandwidth spectrum since it defines the capacity of the oscilloscope to show the signal precisely.

If the frequency of the signal rises, the power of the oscilloscope to calculate the signal reduces precisely.

And thus, the wider the bandwidth spectrum, the higher the frequency you will analyze.

Therefore, in the same manner, as the sampling rate, you can use the rule of five to guarantee that the bandwidth of the oscilloscope is wide enough to calculate at least 5 times the bandwidth range that may be needed for the calculation.

This may also allow you to locate the definitive 5th harmonic and, thus, to decide the form of the signal.

Memory capacity

When you’re looking through the capabilities of a scope that you plan to purchase, be sure and keep an eye on the processing space it has, and even though it has a high sampling rate, it only implies that it uses further memory when capturing signals.

You can also ensure that the o-scope has enough memory space to capture the appropriate signal.

The probes

These are essentially the very devices that enable the USB oscilloscope to conduct accurate measurements.

And even a scope with a high sampling rate as well as a wide bandwidth will not be of many benefits without them.

However, it doesn’t mean that a single probe should be used for an o-scope. You should make sure that all attached probes are of the same range and are compatible with both the sampling rate and the bandwidth.

Number of input channels

The amount of outlets that the o-scope carries is what defines how much information it can handle and what plays such a significant part in pricing.

Bearing in mind your budget, make sure that you see if the oscilloscope you wish to purchase has an appropriate number of channels to enable you to conduct tasks that you need an oscilloscope.

Software

USB o-scopes take on different types of waveform properties depending on the signal that is obtained on the probes attached to some piece of equipment to test.

These properties vary from frequency, time period, amplitude, vibration, and several others. Taking the USB oscilloscopes via the probes, they are then extracted and sent to the PC via a USB link.

They can also translate sound and vibration signals to electrical impulses, which can then be conveniently viewed on the panel of your PC or the built-in screen of certain oscilloscopes.

In addition, due to USB 2.0 connections, you may also move data at an impressive pace. You can instantly grab and save waveforms to a computer where we theoretically have plenty of room, taking into consideration the amount of external storage gadgets that you can have.

Final thoughts

The gadgets mentioned above are some of the better USB o-scopes you will find on the U.S. market. And now you know what to check when buying a USB oscilloscope. Make sure to test the device (if possible) before making a final decision. Or, at least, read a few unbiased reviews of each specific model.
