Best Digital Oscilloscopes

Although this kind of device is relatively new, there are still different models in the market. However, our personal opinion is that digital oscilloscopes are the best in this game. So, we are eager to present to you some of the top digital oscilloscopes from the market.

Rigol DS1054Z Digital Oscilloscopes

Rigol DS1054Z Digital Oscilloscopes

Any person who works with oscilloscopes knows how helpful probes can be. However, most brands fail to include a helping tool. This element causes slower processing, which ultimately costs you time and effort.

However, Rigol makes sure you do not have to face such issues. Hence they not only give 1 but 2 different probes. Both the tools are double passive modes, so, it packs more power.

Moreover, the DS1054Z has 50 MHz bandwidth with multiple channels. The four different channels enable a speedy transmission of data. As a result, real-time sampling becomes easy. It also means that this device follows the RTS system.

Since the model has 12 Mpt memory capacity, it can hold the data for a more extended time and display for longer as well.

Moreover, you can buy software and upgrade the memory to 24 Mpt whenever you want. So, dealing with more massive data sets becomes manageable, and with that, it can capture up to 30,000 waveforms.

The display is also large and spacious with ultra-vision technology. So, whatever appears on the screen will be clear as water. With this feature, you can reduce the chances of misreading completely.

It is a powerful machine, but you can carry it with ease since it is so lightweight. The durable plastic body allows the tool to be portable. However, you do not have to worry about it breaking.

What to Look for in a Digital Oscilloscopes

Now that you have a list of some of the best digital oscilloscopes, it is time to know more about each feature. Knowing the reason and usage of these features will help you decide.

Bandwidth

oscilloscope bandwidth

The higher the bandwidth, the better the output. So, if you have big projects and multiple signals, then choose a product that has at least 50 to 100 MHz bandwidth. Digital oscilloscopes tend to have more than or equal to 50 MHz anyway.

Size and Structure

You can buy mini oscilloscopes, desktop oscilloscopes, or regular oscilloscopes; the options are endless. So, depending on your work, you can go for any of them. However, you should know that a mini oscilloscope will have slower output, but they will be compact.

Channels

oscilloscope channel

Channels are vital for oscilloscopes. It determines whether you can do two jobs at a time. So, if an oscilloscope has only one channel, it is better to avoid that product. Moreover, some brands will also allow you to process both analog and digital signals. So, you get more versatility with one product.

Sampling Rate

The rate at which the device captures each signal to form a wave is the sampling rate. So, naturally, a higher sampling rate means faster output. However, oscilloscopes that are smaller in size will have a lower sampling rate.

So, if you do not want that, go for regular oscilloscopes. Also, memory capacity determines how fast the sampling happens. If the capacity is more, then the visuals will stay on the monitor for a long time.

Display

Digital oscilloscopes have a range of displays. You can get color displays, trigger displays, and even cursor modes. So, based on your needs, you should purchase the oscilloscope. However, always keep an eye for the resolution. If the screen resolution is terrible, then analyzing will become difficult.

Connectivity

There are multiple ways of connecting the oscilloscope, but wireless modes are LAN or Ethernet. However, these connections can have unwarranted disturbances. On the contrary, you can use USB cables as well.

Frequently Asked Questions

Below are some of the most commonly asked queries regarding digital oscilloscopes:

Can digital oscilloscopes be handheld?

Yes, it can be handheld.

How can I track a wave?

Some brands have monitors with cursors using which you can track.

Can digital oscilloscope function on analog?

No, but some brands do provide analog functionality.

What is the power source for oscilloscopes?

Oscilloscopes run on batteries.

Can I control the frequency input level?

No, the machine will accept frequencies within the given range.
