PicoScope 4823

The 4823 is the world’s first high-speed, high-resolution, 8-channel automotive oscilloscope, and is fast enough for CAN, CAN FD, and FlexRay including serial data decoding. It is ready-configured for automotive probes and includes more than 150 Guided tests, plus access to thousands of comparisons in the Pico waveform library which now supports 8 channels.

PicoScope 4823 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.

PicoScope guided automotive tests

PicoScope guided tests

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

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

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

As vehicle technology changes we continue to add more tests through the 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 rotation 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 store customer details too. 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. Included free of charge, this software turns 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

Did you know that your PicoScope also can operate as a highly accurate and efficient battery and charging circuit tester? This allows you to test your customers' vehicles without the need for dedicated, expensive test tools.

Using PicoDiagnostics, you can check the battery, starter, alternator, and wiring, all in one quick test. Easy-to-understand reports with red, amber or 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 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 will discover starting issues caused by corroded or 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. This report is fully customizable with your own company details and logo to give a professional appearance.
