NVH Advanced Kit in Carrying Case – PQ429

NVH Advanced Kit in Carrying Case – PQ429

The Pico PQ429 NVH Advanced Kit is an advanced diagnostic kit designed for identifying noise, vibration and harshness (NVH) issues in vehicles. It allows technicians to analyze vibrations and sounds generated by mechanical components and helps locate the source of problems that can be difficult to identify using conventional diagnostic methods. The kit includes four PicoBNC+ three-axis accelerometers and four NVH microphones, allowing measurements to be taken at different locations on the vehicle and the recorded signals to be compared. It is particularly useful for diagnosing wheel bearings, suspension components, engine and transmission mounts, and other drivetrain components. With four accelerometers, it is possible to monitor vibrations at all four corners of the vehicle simultaneously during a single road test. This helps locate faults more quickly without repeatedly repositioning sensors and performing additional tests. All components are supplied in a carrying case, which provides convenient storage and protects the accessories during transport.
The system is compatible with PicoScope Automotive oscilloscopes equipped with PicoBNC+ connectors.

NVH Noise and Vibration Diagnostics

NVH diagnostics help identify the source of unwanted noise and vibration by analyzing their frequencies. Instead of replacing parts based on assumptions, technicians can perform measurements and relate the recorded signals to the operation of individual vehicle components. With four accelerometers, it is possible to analyze vibrations along twelve axes simultaneously (4 × XYZ). This allows technicians to compare four components, such as all four wheel bearings, different suspension mounting points or various sections of the drivetrain. Measurements can be performed during road tests or stationary testing, for example while running the engine at increased RPM.
The diagnostic process involves:

1. Measurement – the accelerometers and microphones record vibrations and sounds generated by the vehicle.
2. Identification – the software analyzes signal frequencies and helps associate them with specific components, such as wheels, the engine, bearings or the driveshaft.
3. Comparison and confirmation – simultaneous measurements at four points help determine where vibrations are more pronounced and verify the suspected source of the problem.
4. Repair verification – repeating the measurement under the same conditions helps determine whether the source of the noise or vibration has been eliminated.

PicoBNC+ Technology

The kit uses PicoBNC+ technology, which simplifies sensor connections and measurement setup.
Key advantages include:

• Automatic sensor recognition – the software identifies the connected sensor and automatically applies the appropriate measurement settings.
• Three-axis vibration measurement – each accelerometer records vibrations along three axes (X, Y and Z), using a single PicoScope oscilloscope channel.
• Simultaneous measurement at four points – four accelerometers allow technicians to compare vibrations at different locations on the vehicle during a single test.
• 12-axis vibration measurement – vibrations can be monitored simultaneously at four points when the accelerometers are connected to a four-channel oscilloscope.
• Direct PicoBNC+ connection – sensors connect directly to a compatible oscilloscope without requiring additional interface modules.
• No batteries required – PicoBNC+ NVH sensors are powered directly by the oscilloscope.
• No additional activation required – the kit does not require activation codes or additional registration.
