Comparison waveforms

Workshop management system from Pico

Published:  22 September, 2014

The latest free software update from Pico Technology contains what it believes will be one of its most popular features to date - the ability to search a library of waveforms uploaded by PicoScope users from around the world. Steve Smith, Automotive Applications Specialist at Pico Technology says: "I cannot remember how many times it would have been useful to have a comparison waveform for a circuit under test, especially when comparing camshaft/crankshaft timing. Often this would involve sifting through your own library or ringing round colleagues in the hope you might get lucky". PicoScope users everywhere can now share experience regarding good and faulty systems across any vehicle. Over 450 waveforms have already been uploaded by beta testers of the new software. This feature is available to all users with a PicoScope 3000 Series or 4000 Series automotive scope. You can share your own waveforms to the library, enabling everyone to view, download and save your uploaded data. The Waveform Library Browser has comprehensive search options allowing you to locate a relevant waveform for a specific manufacturer or model. You can also search for a waveform using just the engine code or ECU type, so you can locate a relevant entry that may have been saved with different vehicle details.

  • The next generation of scopes 

    The PicoScope 4225 and 4425 are the new 2 and 4 channel automotive scopes which replace the long-serving PicoScope 4223 and 4423 and which provide a number of new features and upgraded performance for the same price as the older scopes. New features provide technicians with additional measurement capabilities and techniques. These capabilities allow the capture of more information and finer detail, over extended periods of time. 'ConnectDetect' is a new feature that confirms on-screen and on-device, that your probe has made connection to the circuit, ideal for hidden connectors. Read more about this in our TestBench on page 35. The BNC input channels are isolated from each other and from USB ground, allowing the technician to directly measure across components, carry out voltage drop tests, test reverse polarity motors and measure floating ground sensors using all inputs at the same time. The input range has been increased to ±200V, reducing the need for attenuation when testing injector circuits, for example. The new scopes can capture up to 400 million samples per second and can measure high speed CAN and FlexRay signals. The new generation scopes have eight times the memory of their predecessors. More samples can be taken and finer detail is revealed when zooming, with the additional benefit of more waveform buffers to review when looking for elusive, intermittent faults.

  • Online parts system 

    The Webcat online parts system from GSF Car Parts now includes optional Autodata technical information. By using the VRM look-up, users can view the full parts catalogue, repair times and now Autodata's Technical Data on one screen. Modules include fault codes, key programming, service schedules, wheel alignment, air con, component location, known fixes and bulletins, and much more. Real-time price and availability checks are provided by your local GSF Car Parts branch and an OE and aftermarket part number cross-reference facility can save you time.

  • Get a first-time fix 

    A 15% discount on version 13 of the Diagnostic Assistance software, written by James Dillon, is available to all Top Technician entrants during May. The software is said to be an ideal companion for a scan tool, designed to help you diagnose faults more accurately and quickly to achieve a first-time fix. Version 13 covers 414 different topics, including 182 comparative waveforms and guided component tests on 95 different sensors and actuators. If you have previously entered Top Technician, use the discount code 'TopTech15' during May at to get 15% off - you can enter Top Tech 2015 at in order to receive the online test this Autumn and qualify to use this code.

  • Analyse noise on the move 

    The PicoDiagnostics NVH (Noise, Vibration, Harshness) kit from Pico Technology provdes real-time diagnosis in the form of either a bar graph, frequency chart, RPM order or road speed view. You can begin recording before a road test and play it back for analysis after, so you can keep your attention on the road. No external memory is needed as the file can be saved to your laptop's hard drive. It plugs into a PicoScope and records up to 500 seconds of data, includes an accelerometer and microphone, gives automatic analysis and detects multiple vehicle vibrations. There is also a customer report function. If you do have a PicoScope and want to make sure you are getting the most out of it, or are thinking of purchasing one, a Professional Diagnostics Ltd engine management diagnostics two-day course is available. It introduces basic working principles of engine management systems, component testing and system testing using oscilloscopes. A certificate of completion is presented to qualifying delegates. The course runs at Delphi in Warwickshire, in Surrey and also Lancaster.

  • From strength to strength 

    A further 62 part numbers, incorporating 25 brake discs, 21 filters and 16 hub assembly kits, join Comline's 7,500-strong product range. The products cover all major European, Japanese and Korean vehicles and include an air filter for Fiat 500, oil filter for Renault Master, Nissan Qashqai+2, Vauxhall Movano, a brake disc for BMW's 2, 3 and 4 Series and a hub assembly kit for the Nissan Qashqai.
