Cheaper than most, this instrument has everything you need to get started with Oscilloscopes. This handheld unit has the ability to measure signals up to 200 kHz which is good enough for many applications including audio. The unit comes with a 1x/10x BNC oscilloscope probe and allows you to measure signals up to 50 Vpeak.

While admittedly not perfect, some reviews say that it can be a bit finicky, most people agree that this is an excellent buy for the money, and can more than fulfill the needs of most hobbyists looking for their first oscilloscope!

Specifications:

  • 200 kHz Bandwidth
  • 1 MSps Sample Rate
  • 2.4” LCD Display

Complementary Products

As you build out your electronics lab with an oscilloscope purchase here are a couple of products that you might find useful:

Koolertron Dual-Channel Arbitrary Waveform Signal Generator

This signal generator can generate a variety of signals that can be input to and studied with the oscilloscope.

The Koolertron uses a Dual-channel Direct Digital Synthesizer and TTL electric level output to generate precise, stable, low distortion output signal. Waveforms include Sine waves, Square waves, Triangle waves, Sawtooth waves, Pulse waves, white noise, user-defined waveforms and more.

HANTEK Oscilloscope Probes

An additional set of reliable, cost-effective probes and accessories that can be used with your oscilloscope.

These probes feature a robust design and are usable with oscilloscopes having bandwidth up to 100 MHz. The Hantek probes have a Modular Construction with a Coaxial Design and Coaxial Reed Switch. An Accessory Pack includes 8 Marker bands, 2 Tip locating sleeves, 2 Mini Alligator Clips and Ground leads, 2 Interchangeable Probe Clip Tips. As well the probes have the 1x and 10x attenuation options.

Is an Oscilloscope worth buying?

If you’re interested in working hands-on with electronics – building and testing circuits, then it definitely is worth it. The first instrument I bought when I started my electronics lab was an analog oscilloscope made by Hewlett Packard. While it lacks the bells and whistles of a modern digital oscilloscope, it is an amazing machine.

Are Cheap Oscilloscopes worth it?

Oscilloscopes are measurement instruments and the lower the cost, the lower the quality of the hardware and the measurement accuracy. Cheap oscilloscopes make sense in two situations:

  • You’re a beginner and want a starter scope to learn and work with
  • Measurement accuracy is not a major concern. For instance you want to want to see if there’s a 10 MHz signal and you’re not concerned with measurement precision – just that it’s approximately 10 MHz

What can an Oscilloscope do that a Multimeter cannot?

A multimeter is a handheld instrument that is used to measure voltage, current, resistance and continuity. An oscilloscope is a benchtop instrument that enables the measurement and display of time varying signals.

Here is a summary of what an oscilloscope can do that a multimeter cannot:

  • Measure multiple time varying signals simultaneously and display them as voltage versus time
  • Measure the frequency content by performing a fast fourier transform operation on the signal
  • Perform protocol analysis on signals

What is the Best Oscilloscope for Beginners?

If you’re starting your journey into the world of electronics, the YEAPOOK ADS1014D is a great beginner instrument. A cost-effective product that’s packed with features including a built-in DDS signal generator.

The 100 MHz bandwidth allows you to measure digital signals on Arduino and other hobbyist development boards. The scope has two channels which allows the measurement of clock and data lines simultaneously as is often required.

Is a 50 MHz oscilloscope enough?

A 50 MHz oscilloscope is good enough you want to accurately measure square waves that have a maximum frequency of 10 MHz. A 50 MHz scope will allow you to observe signals up to 50 MHz, however the measurement accuracy will decrease as the frequency is increased beyond 10 MHz.

How do you choose an Oscilloscope?

There are many criteria and features and it is easy for a buyer to become quickly overwhelmed with specifications, definitions and numbers. We’ve done the heavy lifting of going through technical specifications of various products and through our experience using oscilloscopes, have narrowed things down to six major considerations. Here is the final list with an explanation of why they matter in our analysis.

Bandwidth

this is one of the most important specifications of an oscilloscope. If the bandwidth of an oscilloscope is 100 MHz, that means that it can measure signals with frequencies between DC and 100 MHz. Input signals at frequencies higher than the bandwidth cannot be measured accurately.

Sample Rate

This is a measure of how fast the scope samples the input signal. A good rule of thumb is for the sampling rate to be at least five times the maximum input signal being measured. With our top pick Siglent Scope you can see that the sampling rate is exactly 5x the bandwidth while in the case of the Hantek it is 10x the bandwidth. The higher the sampling rate, the better the resolution of the measured signal and the greater the likelihood that glitches and other intermittent events will be reliably captured.

Form Factor

This depends on the use case for the oscilloscope. Do you want to use it in your lab or take it on the road? As the form factor changes, there are a number of performance tradeoffs that can be made to keep the product affordable.

Typically, a larger unit such as the Siglent benchtop is able to accommodate more sophisticated electronics, larger internal processors, screen size and has better usability. As well a portable unit with specifications comparable to a benchtop will be more expensive. This is indeed the case with the Hantek relative to the Siglent.

Memory

This allows the oscilloscope to store data samples associated with the input signal. Put simply the larger the size of memory the longer your captured waveform can be. The longer the captured waveform the more likely you are to catch intermittent events. However, as the memory is increased so also does the amount of processing required to access it. As the processor then turns its attention to accessing this memory, there is a risk that it will miss other intermittent signals. So there’s really no free lunch here!

Number of Channels

This is important as it represents how many signals can be captured simultaneously. You may for instance want to use your oscilloscope to observe one or more control signals as the power is turned on. You may want to look at time delays between two signals. A single channel won’t do in this case. The oscilloscopes we have presented in this review have either 1 or 2 channels. However, there are scopes with 4 and more channels.

Usability

This is an important factor to consider when purchasing any product. Aside from a few quirks here and there, all the scopes we have listed in this review are quite user friendly.

Price

This is always a consideration when purchasing any product. In this article we have presented products at four price thresholds with performance that is consistent. If you are committed to learning about electronics and building out your lab then it makes sense to go with the Siglent. Alternatively if you’re just starting out and don’t want to make a $300+ commitment, then the JYETech unit is a good option.

Summary

An oscilloscope is a must-have tool for anyone working with electronic signals. Whether you are a hobbyist or a professional, an oscilloscope is one of the most useful pieces of test equipment.  In this article we have recommended four different oscilloscopes, each of which have unique attributes and score very high when you consider their specific use case.
