4.14.1 / 5
It’s the best PC based automotive oscilloscope for buyers who need multiple channels.

For those who need the best automotive oscilloscope with a lot of channels, the Hantek 1008C is a great option. It’s a PC-based oscilloscope with a programmable waveform generator, ideal for most home automotive applications.

The functions of the Hantek 1008C are what set it apart from other automotive oscilloscopes. Along with the waveform generator, it has a built-in FFT function and basic mathematic functions, too. It also comes with 20 automatic measurements and auto cursor tracking functions.

Compatibility is the only major drawback of the Hantek 1008C. The included software can only be installed on Windows 8 or 10 PCs. Since the product is discontinued, it’s also no longer being updated. If this isn’t an issue for you, however, it’s certainly the lowest per-channel cost you’ll find in an automotive oscilloscope. 


  • 8 channels 
  • Programmable wave generator
  • Automatic cursor tracking and measurements
  • Store, record, and playback dynamic waveforms
  • Software is easy to install and use


  • Needs PC to operate (Windows 8 or 10)
  • Not usable for all automotive functions

The Hantek 1008C is the best PC based automotive oscilloscope for buyers who need multiple channels, though its limited software compatibility may be an issue for some users.

4.84.8 / 5
It’s the best automotive oscilloscope for professionals.

For professional-level diagnostics, the Rigol DS1054Z Digital Automotive Oscilloscope is the best digital automotive oscilloscope on the list. It has the wide waveform capture rate, deep memory, and full-color display you need for a thorough, accurate analysis.  

The Rigol DS1054Z is surprisingly easy to use, considering how many features it offers. A large 7” display with high pixel resolution lets it show readings from all 4 channels on the screen at once. This speeds your diagnosis and makes it easier to find inconsistencies between circuits. 

The only disappointing thing about the Rigol DS1054Z is that the advertised price is a bit deceptive. Many of the features are only available on a 30-day trial basis without a paid upgrade. Considering its price is already on the high side for an oscilloscope for automotive troubleshooting, this puts it out of the budget of many hobbyists. 


  • 4 channels 
  • Easy to read color display
  • Simultaneously view readings from all channels
  • User-friendly and intuitive
  • Display offers multi-level intensity grading
  • Deeper memory with UltraVision technology


  • More expensive option

<strong>SainSmart DS0212</strong>
SainSmart DS0212 Handheld Automotive Oscilloscope
4.34.3 / 5
It’s a super-portable automotive oscilloscope with an impressively detailed display.

We love the design of the SainSmart DS0212 Handheld Automotive Oscilloscope. The screen is relatively large and easy to read considering its compact size. 

Unfortunately, the inner workings of the SainSmart DS0212 aren’t as impressive. Its sample rate and bandwidth are among the lowest on the list. Though its display is color sensitive, this limits its use and accuracy. 

The SainSmart DS0212 does offer 2 channels, as well as easy connectivity to a PC to download waveform data. If you don’t need high precision from your measurements this SainSmart automotive oscilloscope is a convenient option, but it’s not the best choice for everyone.


  • Detailed color-sensitive screen
  • Compact enough to carry in your pocket
  • Connects to Windows computer to download data
  • 2-channel operation
  • Quick, simple set-up and navigation


  • Low sample rate and bandwidth

4.24.2 / 5
It’s a compact and modern PC-based oscilloscope, designed to work well with any Windows operating system.

Another PC-based oscilloscope from Hantek that’s worth checking out is the HT6022BE. It’s a compact oscilloscope that comes with everything you need to start using it. Since it’s a newer model than the Hantek 1008C above, it has a wider compatibility and more frequent software updates.

Overall, the Hantek HT6022BE is a very user-friendly PC-based oscilloscope. Everything you need to use it is included in the box. Software installation and set-up is a quick, painless process, and the software itself is intuitive to navigate. 

While the Hantek HT6022BE is compatible with a wider range of Windows operating systems, it still can’t be used on Apple-based computers. This is its only issue, from a design standpoint. The casing of the Hantek HT6022BE is made of durable aluminum with high heat resistance, perfect for automotive applications. 

Compared to more expensive automotive oscilloscopes, the Hantek 6022BE has a relatively low sample rate. Still, it gives you everything you need for the majority of automotive applications. It’s a great buy if you’re looking for a user-friendly PC-based oscilloscope. 


  • Slim and compact design
  • Durable anodized aluminum housing
  • Includes FFT and mathematic functions
  • Easy to install and use
  • Real-time sampling


  • Not compatible with iOS devices
  • Relatively low waveform capture rate and sample rate

The Hantek 6022BE is a compact and modern PC-based oscilloscope, designed to work well with any Windows operating system. Though the capture rate is on the low side, the build quality and functions make up for this lack.

What Is An Automotive Oscilloscope?

An automotive oscilloscope is a tool for diagnosing sensors and circuits. The power from these components can often change too quickly for a digital multimeter to measure them effectively. An oscilloscope can detect issues with electronic components even before diagnostic trouble codes trigger.

When signals enter the oscilloscope through the probe, the device graphs the signal based on its rate of change over time. This gives a more accurate picture of the components performance than multimeters. It’s also important for detecting intermittent issues other diagnostic tools miss.

There are many kinds of oscilloscopes out there for other applications, including manufacturing or scientific purposes. An automotive oscilloscope includes the pre-set data and capacity you need for auto components.

How To Use An Oscilloscope

  1. Identify the controls on the oscilloscope. Make sure you know how to change the horizontal and vertical increments of the grid, and that it’s set to the correct range for the component you’re measuring.
  2. Turn on the oscilloscope. When nothing is plugged in, you should see a flat line, indicating no voltage change. If there is input when nothing is connected to the probe, disconnect and reconnect it. If the screen is blank (no flat line), make sure you’re on the correct input. Also check the zoom; you may be tightly focused on a blank area of the screen.
  3. Connect the probe to the component or circuit you want to measure. The flat line should turn into some kind of waveform.
  4. Adjust the horizontal and vertical divisions until the waveform oscillates only within the confines of the screen, and is large enough to discern changes. If the waveform seems unstable and difficult to see, adjust the trigger level.
  5. You should now be able to determine how the component is functioning. The trickiest part of using an automotive oscilloscope is learning how to set the controls for various situations and components. If you’re having difficulty reading the circuit, connect the oscilloscope to a functioning circuit, which may be easier to graph and will tell you what settings work best.

Final Thoughts

Generally, the more you pay the more features and accuracy you’ll get from an automotive oscilloscope. Consider your needs before you buy. Most home mechanics don’t need the more extensive features offered by more expensive models.

All 10 of the automotive oscilloscopes above are reliable and convenient ways to test your engine components. We hope the reviews above have helped you find the right one for your garage!
