Oscilloscopes are one of the most important tools used by electronic engineers that allows them to visualize waveform signals on the device for further observation and problem-solving. The oscilloscopes are also needed in almost every electronic laboratory where electronic hardware is being tested. It is useful in multiple fields of studies including RF design, electronic circuit design, electronic manufacturing, servicing and repairing of electronic devices, and many more. Here are some of the many important factors of an ideal oscilloscope.

  • Bandwidth: Similar to the network, the bandwidth on an oscilloscope refers to the range of maximum level of frequency it can measure. The low bandwidth oscilloscopes have a comparatively shorter frequency response range than high bandwidth oscilloscopes.
  • of Channels: The number o0f channels on an oscilloscope is quite important. Traditionally, all-analog oscilloscopes have been operating with two channels. But, the newer digital models offer up to 4 channels for detailed results.
  • Sampling Rate: Sampling is necessary to reconstruct the signal perfectly. The sampling rate of an oscilloscope refers to the number of observations recorded by the device per second. Naturally, the device with a higher sampling rate will provide you with more accurate results.

We will be including all of the necessary information with each of our picks so that you can understand them completely. There is also a “Buying Guide” present later on in the article to help you with the same.

Buying Guide For The Best Oscilloscope

Selecting an oscilloscope can be a difficult task, especially if you do not have prior experience with these devices. The Oscilloscopes are very intricate devices and each variant is suitable for a limited set of applications. Thus, if you wish to buy one, you need to carefully pick the perfect option from the thousands of options available out there.

While going through the best oscilloscopes provided in our article today, you must be familiar with some technical specifications like the bandwidth, number of channels, and overall performance range of a device. But, specifications are simply not enough to get the perfect oscilloscope as most of the devices you have seen today feature similar properties. Thus, we are bringing you a specific buying guide for the best oscilloscopes so that you can get an idea about oscilloscopes in general and make the correct choice.

Analog vs Digital Oscilloscope

If you have been working with electronic devices such as oscilloscopes, you must know that the traditional oscilloscopes were analog. These analog devices would operate over 2 channels with being sensitive enough to calculate most signals.

The only major problem in the analog devices is the room for human error because of the visual scale and the limitation of record length. Now that there are digital variants available for an oscilloscope, you can easily get up to a 4 channel device that will be much more helpful in generating precise results. You will find the digital oscilloscopes even with 2 channels with similar accuracy.

Sampling Rate

The sampling rate of an oscilloscope refers to the reconstruction of a signal in the oscilloscope. In simpler words, the frequency of samples generated on the device per second. If the sampling rate is high, the accuracy of your results will be higher and more precise due to the larger amount of generated samples in a given time.

There are 2 types of sampling rates that are real-time sampling rates and equivalent times sampling rate. Out of which, you should only pay attention to the real-time sampling rate as only that affects the actual performance of the oscilloscope at the time of an experiment.

Bandwidth Capacity

The bandwidth of a signal is its intensity. Sound propagates in the form of waves with a certain highest and lowest intensity which is represented in MHz. To be able to measure this intensity, the oscilloscope should also have a similarly high capacity.

For example, if the signal you are measuring has a bandwidth over 100 MHz, it will not be detected by a 50 MHz oscilloscope, rendering it useless for the application. A high capacity oscilloscope on the other with a capacity of 200 MHz can easily measure these signals along with high-intensity signals up to its bandwidth limit. Thus, having a high bandwidth capacity oscilloscope allows you to perform higher experiments with promised results.

Record Length

The record of an oscilloscope is basically its capacity to store previous results. While performing an experiment, you will usually take a significant number of readings to avoid the inaccuracy in results caused by external factors.

In such a case, you will require all of your previous results to get to a precise conclusion. With a higher record length, your device will be capable of recording and storing larger numbers of results for you simultaneously. It is not crucial if you are a hobbyist but it is certainly a necessary factor for professional workers.

Conclusion

It does not matter whether you are a professional worker, an experimentalist, or simply a hobbyist who is looking forward to studying and understanding the workings of an oscilloscope as you will require a proper oscilloscope by your side. We have included a variety of different options on our list today so that you can find the perfect oscilloscope under your preferred budget range. If you have not found a decent option yet, try one of our top recommendations present below.

  • To put it in simple words, oscillometric aren’t the cheapest instruments. Still, options like the Siglent Technologies SDS1052DL Digital Oscilloscope are comparatively cheaper than most other options on the market. It is the cheapest device on our list today featuring a 50 MHz bandwidth range and dual-channel operation.
  • If you have a professional application in mind where you are going to measure large quantities of signals, the Hantek MSO5202D Digital Oscilloscope is the right choice for you. It is operated over 200 MHz bandwidth capacity over dual channels. Apart from that, it is better in terms of observation thanks to the large 7 inches WVGA LCD display with an 800 x 480-pixel resolution display.
  • Long-term functionality is often expected from high-end devices like an oscilloscope. Hence, our next recommendation would be the Owon MSO7102TD Digital Mixed Oscilloscope as it is a premium device featuring a 3 year long warranty period. It has 100 MHz bandwidth capacity and has a 16 channel logic analyzer while the device operates over 2 channels.
