NEW Generation Automotive Oscilloscopes

Pico Technology's Automotive Scopes

When you buy the World Famous PicoScope Automotive Oscilloscope you get industry-leading performance that is both affordable and easy to use. With the introduction of the PicoScope 4225 and 4425, all aspects of performance have been improved – but the price remains the same!

Unlike most digital storage oscilloscopes, which typically have 8-bit vertical resolution and poor DC accuracy, The Pico Automotive Oscilloscopes are accurate to 1% and have 12-bit resolution. This gives a vertical resolution of 4000 ‘dots’ compared to the usual 100 or 200 of most other automotive scopes.

As well as the high vertical resolution, Pico automotive oscilloscopes also feature large memory buffers – making it possible for you to capture large, complex signals, automatically trigger on any event and then expand areas of interest to show the fine detail of the signals.

  • High resolution and precision
  • Large sample memory allows waveform detail to be expanded
  • Unlimited storage of waveforms and settings
  • Advanced trigger modes capture intermittent faults
  • Free software updates and technical support

The PicoScope automotive oscilloscopes are specifically designed for use only in automotive applications. With features such as high resolution and accuracy, a large memory buffer, and a high-speed USB connection, PicoScope automotive oscilloscopes offer unrivalled performance, and are suitable for use in the most demanding automotive applications.

You can purchase a PicoScope automotive oscilloscope on its own, or as part of an Automotive Diagnostic Kit

Faster Sampling

The latest PicoScopes can capture signals faster than ever; with sampling rates of up to 400 million samples per second, there is nothing that can escape the scrutiny of PicoScope. It can capture CAN and FlexRay signals, and has the speed to handle future needs as vehicle technology changes.

More Memory

As well as capturing faster signals, the PicoScope 4000 series also outperforms other scopes thanks to the 250 million samples of ‘always on’ memory. PicoScope ensures that you can effortlessly capture every detail of the signal. Never again will you miss those hard–to–find intermittent faults.

Higher Input Range

The high ±200 V input range of the PicoScope 4000 series eliminates the need for external attenuators for most vehicle tests.

Independent Floating Inputs

A major innovation on the 4425 are the independent floating inputs; think of it as 4 separate 1-channel oscilloscopes in a box all sharing the same timebase and control. This means that all inputs can be used in differential mode (e.g. CAN_H and CAN_L signals), or across non-grounded components such as 12V injectors or for voltage drop testing using a single input.

(Maximum 30V common mode voltage difference betweenchannel grounds.)


The new PicoScope 4225 and 4425 scopes include a handy feature to detect when you have made a good connection. When you are trying to probe in those difficult to reach places, the new PicoScopes can display the connection status on your big screen ensuring fewer frustrations with poor connections.

PicoScope Future Proof!

The recently introduced two-channel PicoScope 4225 and four-channel PicoScope 4425 are our 5th generation of automotive PC oscilloscopes. They are 5x faster and have 8x more memory than the previous generation, ensuring they are powerful enough for the next generation of vehicles with new technologies such as CAN FD.

Other innovations include new floating inputs for non-grounded measurements, higher input ranges and ConnectDetect to ensure you have a good connection. The new PicoScopes are also now USB 3.0 connected and powered.

When you purchase any diagnostic tool you not only spend money but you also spend time learning how best to use it. We protect that investment in two ways. First, we develop hardware and software that is easy to use for those starting out with oscilloscopes yet has the power and features demanded by experienced users. Second, we do not compromise on quality or specifications - expect the PicoScope you buy today to still be an essential part of your diagnostic tool box 10 years from now.
