The PicoDiagnostics NVH kits from Pico Technology are the cost-effective answer to the many NVH problems facing technicians today. The software provides a real-time diagnosis to the technician, in the form of either: a bar graph, a frequency chart, a 3D frequency chart, RPM order, road speed view or a time domain view. The ability to start the recording before a road test and playback and analyze the recording back in the workshop, ensures that the driver's attention remains on the road. Saving the recordings couldn’t be easier: Much like our other automotive software, you can simply save the file to your laptop’s hard drive.

The PicoDiagnostics NVH kits make use of the PicoScope Automotive oscilloscopes and are available in a number of configurations to suit your needs. You can be sure that your investment in the PicoDiagnostics NVH kit will benefit your business without the need for further spending. If you already have a PicoScope Automotive oscilloscope, you’re halfway there.

Typical uses

Customer complaints surrounding noise/vibration are subjective at best and present technicians with a challenge even before they can begin diagnosing and rectifying. By applying an NVH kit to the vehicle, the technician has the ability to road-test the vehicle with the customer to obtain all vibration and noise levels. Once this valuable data has been collected, it can be analyzed and compared to previous captures or against donor vehicles. Often what is perceived by the customer to be a “problem vibration” could, in fact, be a characteristic. Now you can present and compare objective data with test results from donor vehicles to reassure your customer that everything is normal. Alternatively, comparing data may highlight a problem with the vehicle and the measurements taken can give the technician the information needed to confidently proceed with a repair. Below are just a few of the typical scenarios where an NVH kit can save you time and money:

• Cabin vibrations at speed
• Engine vibrations throughout the entire RPM range
• Clutch judder or vibration
• Transmission and bearing whine
• Auxiliary drive noise
• Brake judder
• Steering vibrations 

BNC+ Optical balancing kit (PQ316)

The purchase of our BNC+ Optical Balancing kit allows on-vehicle balancing in order to rectify first order shaft vibrations. Included as part of our PicoDiagnostics software, the Propshaft balancing test provides clear advice and guides you through analysis and test procedures:

• Support for pinion flange, single weight, and hose clamp balancing weights
• Step-by-step procedures with help and graphical displays

Workshops, aftersales networks, and technicians must be sufficiently trained and equipped to repair Battery Electric Vehicles (BEVs), Hybrid vehicles, and Internal Combustion Engine (ICE) vehicles. BEVs bring with them new technologies and therefore new measurement and diagnostic challenges. They also bring new hazards into the workshop and the associated risks must be properly handled. With its PicoScope 4425A EV Kit, Pico Technology offers technicians and workshops an all-in-one solution to many of these new problems, as well as covering ICE and Hybrid systems.

The PicoScope 4425A EV kit provides comprehensive diagnostics capability for all types of EV (BEV, MHEV, PHEV, Fuel-cell), and ICE (Diesel, Gasoline, LPG). In combination with the extensive range of Pico accessories, the 4425A covers engines/motors, sensors, actuators, communications buses, noise vibration & harshness (NVH), and basic measurements in a user-friendly system that includes extensive guidance for the technicians. The PicoScope 4425A EV Diagnostics Kit contains all the test equipment required to ensure safety during work on an EV and to investigate any faults that are likely to cause safety issues.

This kit has been designed to provide the essential measurement tools you need for both high- and low-voltage systems, including insulation testing and safety testing. It is based on the market-leading PicoScope 4425A with PicoBNC+® technology and is supported by special EV-guided tests in the PicoScope 7 Automotive software.

PicoScope is a powerful automotive diagnostic tool that gives detailed insights into your vehicle’s systems. It’s user-friendly, with advanced features like waveform comparison, easy data sharing, and non-invasive testing, ensuring you can diagnose issues accurately and efficiently. Whether you’re a seasoned technician or just starting, PicoScope helps you get to the root of problems faster and more reliably.

While a scan tool reads error codes and monitors sensor data, it often misses the root cause of issues, especially intermittent faults or rapid events. A PicoScope provides precise, real-time waveform analysis, allowing technicians to observe electrical signals and component behaviors closely. This helps diagnose complex issues like voltage drops, signal interference, and faulty components. Using both tools together ensures thorough diagnostics, leading to more accurate repairs and reduced diagnostic time.

Oscilloscope testing is non-invasive, allowing for detailed signal analysis without disturbing the system, ensuring accurate and safe diagnostics. Whether you want to check your vehicle's electrical or fuel circuits, suspension and drivetrain, communication systems, or engine/motor, a PicoScope acts like an X-Ray machine allowing you to see and capture changing signals as they happen.

A PicoScope can help you increase first-time fix rates, shorten fault resolution times, and greatly improve your customer satisfaction. PicoScope is trusted by the automotive industry, and used by over 30 major vehicle manufacturers.

To fit with the varied and changing experience levels within a global aftersales network, PicoScope is user-friendly for all skill levels with intuitive easy-to-navigate menus and controls, built-in step-by-step guided tests that set up your scope, and smart probes that configure your software for you. No other scope helps you get started like a PicoScope.

PicoScope includes a market-leading, waveform library with over 10,000 reference waveforms to compare with your captures, helping you quickly determine if there’s a fault in your vehicle

PicoScope makes collaboration easy by letting you directly share and tag waveforms within its library, print them for reports, and export them as images or data files. This flexibility makes it the perfect tool for workshops, teams, and communities.

In addition to giving a rapid return on your investment, PicoScope also continues to improve after the initial purchase with free software updates for the life of your product.

Pico Technology has heavily invested in extensive training materials and content to help PicoScope users start and grow throughout their oscilloscope diagnostic career. The knowledge base includes application notes, case studies, and many videos showing you how to get the most out of your PicoScope. The PicoScope user community is unrivaled.

Automotive oscilloscope kits

For any engineers working on the design of electronic systems, one of the standard automotive oscilloscope kits is ideal. These kits can be expanded to measure NVH, perform shaft balancing or test pressure. As standard, they can decode the following serial protocols:

• CAN bus 
• LIN bus
• FlexRay
• SENT
• 10Base-T1S

There are obvious advantages to using the same tools to help develop vehicles as the dealer network uses to diagnose and repair. Many vehicle manufacturers have taken advantage of this and especially in the early days of a new model's introduction the ability to send waveforms and data back from the field has proved invaluable.
