    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 oscilloscope kits

    The Pico Automotive Diagnostics Kits work with your PC to measure and test virtually all of the electrical and electronic components and circuits in any modern vehicle including:

    • Ignition (primary and secondary)
    • Injectors and fuel pumps
    • Starter and charging circuits
    • Batteries, alternators and starter motors
    • Lambda, airflow, ABS and MAP sensors
    • Electronic throttle control
    • CAN bus, LIN bus and FlexRay

    Find out why PicoScope is like no other oscilloscope with features and benefits that make it the world's leading choice for vehicle manufacturers and aftermarket garages alike.

    Scope or Scan ToolScan tool or scope?

    We are often asked "Should I buy a scan tool or a scope". The short answer is that you need both. A scan tool can often point you in the right direction, perhaps indicating a misfire on a specific cylinder but too often the less experienced technician then ends replacing several parts before the problem is solved. Oscilloscopes should be used:

    • To eliminate guesswork and test individual components before they are replaced. This avoids "parts darts" where more and more parts are replaced until the fault goes away.
    • To find intermittent wiring and connector faults.
    • When a vehicle has a problem but no code has been set or when multiple / misleading codes have been set
    • As the best way to find charging and starting problems.
    • To find problems with actuators such as motors and injectors that are not monitored by the ECU.
    • To identify mechanical problems such as compression and slipped / incorrectly fitted timing belts.

    For the technician oscilloscopes lead to faster, more efficient diagnostics and a better understanding of how vehicle systems work. For the workshop using a PicoScope encourages a "fix it right" culture by reducing the number of parts changed on guesswork. The net result is improved customer satisfaction, increased repeat business and increased profits.

    Open Your EyesOpen your eyes with PicoScope software

    PicoScope 6 is the most advanced automotive oscilloscope software available to date. With award-winning features and intuitive design, this software is designed to make sure you get to the heart of the problem, fast.

    Features such as auto setup, tutorials and the guided tests quickly get new users up to speed. Advanced features such as maths channels, waveform buffers, advanced triggers and reference waveforms ensure the experienced user will not run out of power.  

    The modern user interface is easy to use. There are no old-fashioned knobs and dials. We leave the space free for what matters: your waveforms displayed in crisp, clear high resolution.

    Future ProofPicoScope: 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. 

    PicoScope Guided TestPicoScope 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.

    Waveform LibraryWaveform 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. 

    PicoDiagnostics

    Pico DiagnosticsWith a simple connection to the battery, the PicoDiagnostics software quickly performs the following tests:

    • Compression test. Crank the engine to quickly display the relative compression of each cylinder.
    • Cylinder balance / misfire detect. Compares the power output of each cylinder and highlights misfires.
    • Battery test. Displays CCA, measures state of charge and voltage drop during starting. Gives an overall Pass or Fail.
    • Starter motor test.  Checks starter coil resistance and voltage drop across cables.
    • Alternator test.  Measures charging voltage and current. Checks for excessive diode ripple.

    WPS500X pressure sensor kit 

    Adding the WPS500X to your PicoScope opens up a new world of diagnostics by turning pressure readings into waveforms. In-cylinder waveforms show valve and timing issues, mechanical failures, blown gaskets and blocked catalytic converters. 

    Most pressure sensors can only measure over a limited range (so you need different ones for different tasks). The WPS500X has three ranges in one sensor so it is flexible enough to work right around the vehicle - fuel pressure, transmission pressure, intake vacuum and even pulses from the exhaust.

    Supplied as a complete kit with hoses (compression, fuel, vacuum, bleed) and adaptors (exhaust, M10/M12/M14 plugs and universal).

    Hardware

    PicoScope oscilloscopes - future-proof

    Pico have been designing, manufacturing and improving our oscilloscopes for over 20 years. Our objective is simple: to make the best automotive oscilloscope in the world.

    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 and voltage drop tests
    • Higher voltage ranges (up to 200 V without attenuators)
    • ConnectDetect® to ensure you have a good connection
    • Advanced triggers to capture intermittent faults
    • Hardware filters and frequency measurement
    • 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, so expect the PicoScope you buy today to still be an essential part of your diagnostic toolbox 10 years from now.

    Floating inputs

    Floating input channels are a unique new technology that allows safe, low-noise measurements even in situations where none of the inputs are grounded.  

    Floating inputs allow a single input to perform voltage drop tests (for example, along the battery to starter motor cable) and measurements on non-grounded signals like hybrid electric motor drives. With floating inputs the maximum allowable voltage difference between any two channel grounds is 30 V.

    The inputs can now measure up to 200 V (up from 100 V on the previous generation of PicoScope). A key benefit is that external attenuators are no longer needed for measuring injector voltages. 

    Remember: on a floating-input scope, grounding one input does not ground all the others. You must provide signal and return connections for each input that you are using.cope oscilloscopes - future-proof

    ConnectDetect®

    Making sure that you have a good connection to the signal you want to test is not always easy. With ConnectDetect enabled, indicators on screen, and lights on the scope itself, turn from red to green as soon as a good connection is detected.

    Once a good connection is established, the on-screen icons fade so as not to obscure the waveform. If, however, the status changes (for example vibration causes a probe to become loose), the icons will highlight the change.

    Memory buffer

    The best way to diagnose an intermittent fault is often to set up the scope to measure from several components and wait for the fault to occur. For an intermittent misfire, you might want to capture several minutes of cam, crank, ignition and injector waveforms. These types of tests require an oscilloscope with a "deep" memory buffer, so that you can capture for long periods of time and then zoom in without any gaps or loss of detail.

    With PicoScope you can collect 250 MILLION samples, more than any other automotive oscilloscope. Our advanced "always on" memory technology uses hardware acceleration to make sure that the processing of large amounts of data does not slow the oscilloscope down even when you are using a slower or older PC.

    Deep memory allows long recordings at high speed – you capture a complete test drive whilst looking for intermittent faults. When not using the full memory for a single waveform, PicoScope automatically stores up to the last 10,000 waveforms in the buffer, so you can stop the scope and “wind back time” to see every capture.

    Crisp, clear high-resolution display

    A deep waveform memory gives you a high time resolution, but a high vertical resolution is equally important. It allows you to see small changes in signal such as ignition coil oscillations and the small dip in current when an injector opens.

    Many oscilloscopes only offer 8-bit resolution which allows 256 vertical steps. As most PC monitors have vertical resolutions of over 1000 pixels, this results in a low-resolution "blocky" display. The PicoScope 4225 and 4425 have 12-bit resolution (4096 steps), and when not using the full sampling rate of the scope this can be enhanced to 16 bits (65 536 steps).

    The image shows the same ignition signal captured at both 8 bits and 12 bits. With the 8-bit oscilloscope the coil oscillations are distorted while at 12 bits they are in clear high definition. 

    Fast 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.

    CAN and FlexRay are now common on vehicles, and new protocols such as SENT for digital sensors and CAN FD (up to 5x faster than the current CAN standard) will appear in new vehicles from 2017. The fast sampling rate ensures that the PicoScope 4225 and 4425 have the speed to handle future needs as vehicle technology changes.

    USB 3.0 for power, speed and simplicity

    As with our previous generations of PicoScope oscilloscopes, no external power supply is required and there are no batteries to go flat, just a simple reliable connection to the USB port.

    The PicoScope 4225 and 4425 have the latest SuperSpeed USB 3.0 port to interface to your PC. Don't worry if your PC only has USB 2.0 ports – the PicoScopes are fully compatible with these too. If you have USB 3.0 on your PC you will notice slightly faster screen update rates, faster file saving and USB streaming. As more of our customers move to PCs with USB 3.0, free software updates will ensure that you get the full benefits available from the new standard.

    Our unique fast USB streaming allows continuous gap-free data to be collected straight to PC memory. This makes features like our cylinder balance, battery test and (optional) NVH tests possible. It also allows the oscilloscope to display live, real-time data without waiting for the screen to refresh.

    Advanced features

    Most new users start by using the guided tests to configure all the settings automatically. As your experience grows there are many advanced features to explore. These include:

    Advanced digital triggers. Unique among automotive oscilloscopes, these trigger modes allow you to trigger when there is too long a time gap (such as when an injector fails to fire). They can also be set to trigger and sound an alarm when a sensor signal goes out of range.

    Filters. Some signals are noisy as wires in the loom pick up noise from other wires. The ECU filters this noise out. The PicoScope 4225 and 4425 have selectable hardware filters to remove this noise, so you see what the ECU sees.

    Hardware frequency measurement. Flow sensors and some airflow sensors output a digital frequency signal. Most oscilloscopes can't extract usable diagnostic information from this, but your PicoScope can convert it to a conventional analog waveform (as shown in this MAF sensor example).

    Every aspect of your PicoScope has been designed for a long working life, and it has the performance to ensure it will not be obsoleted by the changing technology in new vehicles. The hardware is robust and reliable with no moving parts or batteries to fail. Combine this with free support and free software updates for the life of the product and its easy to see why a PicoScope is the choice for professional diagnostics.

    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. 

    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 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.

    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.

    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.

    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.
