Automotive oscilloscopes

A PicoScope (sometimes known as a labscope) turns your laptop or desktop PC into a powerful diagnostic tool. Think of it as the X-ray machine of diagnostics, letting you see the changing signals inside wires. You can purchase a PicoScope on its own, but most people purchase one of our award winning Automotive Diagnostics Kits. These money-saving kits contain everything you need – just add a PC.

PicoScope software

deep memory oscilloscope

PicoScope Automotive is the powerful software package that turns your PC into a diagnostic oscilloscope when used with a PicoScope device. PicoScope has been designed to make it easy for you to diagnose vehicle faults. Packed with features such as automated measurements, reference waveforms and the ability to save and print waveforms, PicoScope Automotive is the ultimate tool for your diagnostic toolbox.

Also included is PicoDiagnostics software to quickly test batteries, alternators, starter motors, compression and cylinder balance. Professional reports allow you to show your customer what you have checked and any problems you have found.

Download the software today, which will run in demo mode without a scope attached, allowing you to explore the capability and see how PicoScope can benefit your business and customers.

Regular updates to our software include new features and new tests, and are free for the life of the product.
PicoScope guided automotive tests

PicoScope guided tests

Built into the software are over 150 guided tests ranging from simple injector tests through to more complex topics such as CAN bus testing.

When you select a guided test all settings are configured for you and an example waveform is loaded. Diagrams and photos then show you which leads and accessories you need, how to connect to the vehicle and perform the test.

Once the test has been completed there is guidance on understanding the waveform, how the component works and typical faults / fixes.

As vehicle technology changes we continue to add more tests through free software updates.

Automotive waveform library

Cam vs crank waveforms from the library

Waveform library

The library enables you to share and back up your waveforms online and also search a global database of waveforms uploaded by PicoScope users from around the world.

The powerful search options let you find “known good” waveforms from vehicles identical to the one you are working on. Not sure if you have a slipped timing belt? There are hundreds of cam vs crank waveforms to compare against. Not sure if the cranking current is too high? Download a waveform to compare.

PicoScope software - keeps improving

We have been upgrading and improving PicoScope software for over 20 years. This allows us to make the maximum use of the latest technology both in the oscilloscope hardware and the PC itself.  

The modern user interface is uncluttered and easy to use. There are no old-fashioned knobs and dials. We leave most of the space free for what matters: your waveforms.

Recent new features include:

  • 720 degree timing rulers: ideal for looking at engine timing (see waveform showing crankshaft, camshaft and in cylinder pressure).
  • Channel labels: it's important when saving a file to identify what each channel is measuring but it can be time-consuming.  With channel labels you just type in a few letters and a time-saving list of names is presented.
  • Vehicle database: a list of makes and models is included with the ability to also store customer details. The last few vehicles worked on are stored in a list for quick recall.

Software upgrades are free for the life of the product and download in the background while you are working.

PicoDiagnostics

Alongside our PicoScope 6 software you also have our highly powerful PicoDiagnostics software free of charge to use, turning your PicoScope into a highly powerful diagnostic device. See the tests listed below for a glimpse into how PicoDiagnostics can turbocharge your performance.

relative compression test

Compression test

Check for mechanical issues in seconds: simply clip the test leads to the battery and crank the engine. The relative compression of each cylinder is shown in an easy-to-understand bar graph format.

To show absolute compression, add an optional pressure transducer to one cylinder and the software will calculate the pressure for all cylinders in bar or PSI.

battery, starter and alternator test

Battery, starter and alternator test

Did you know your PicoScope can also operate as a highly accurate and efficient battery and charging circuit tester, allowing you to test your customer’s vehicles without the need for dedicated, expensive test tools?

Using PicoDiagnsotics you can check the battery, starter, alternator and wiring all in one quick test. Easy to understand reports with red / amber / green indicators can be printed for customers either to show the electrical system is in good condition or to explain why a component needs replacing.

The battery test checks the state of charge, the voltage drop during starting and compares the cold cranking amps (CCA) with the rating for the battery. 

The charging test checks the alternator is correctly charging the battery and and spots problems such as overcharging or excessive ripple due to a blown diode.

The starter test helps identify a failing starter motor by measuring its coil resistance. 

The drop test measures the voltage drop (and resistance) of the cables running from the battery to the starter motor. This finds starting issues caused by corroded / damaged battery cables or poor connections to the chassis ground. 

Once your test is completed, you can print out a copy of the report for your customer that is fully customizable with your own company details and logo to give a really professional appearance.

Cylinder balance / misfire detect

Cylinder balance / misfire detect

Check for misfires and check if each cylinder is contributing the same amount of power with the cylinder balance test.

Simply connect channel A of the PicoScope to the vehicle battery and start the engine. The software detects changes in engine speed as each cylinder fires. An easy-to-understand bar graph display shows the relative power output from each cylinder.

Please note: this test will not work correctly on certain vehicles that disable cylinders for emissions control reasons or on low-compression engines with 8 or more cylinders.

automotive oscilloscope software

Software that grows with you

PicoScope has been designed to be easy to use for the beginner - the guided tests quickly get you up to speed and if you are confident using a multimeter and scan tool you will have no problem with a PicoScope.

PicoScope also has a depth of features that makes it the oscilloscope of choice for expert users ranging diagnostic specialists to designers of vehicle systems. For vehicle manufacturers, having dealers, field service technicians and designers all use the same tool has proved immensely valuable.

Some of the advanced features include:

  • Serial decoding (CAN, LIN and FlexRay)
  • Mask testing. Draw a mask around a known good waveform, the software then saves or alarms every time a waveform fails.
  • Advanced maths. Plot changing frequency and duty cycle. Add filters. Add, subtract and perform complex equations between channels.
  • Custom probes. Scale the output from linear and nonlinear sensors into real-world values.

In short we believe that PicoScope is the best automotive oscilloscope software for new and experienced users alike. But don't just take our word for it: read some reviews from our users.
