NVH Starter Kit – PQ426
The Pico PQ426 NVH Starter Kit is designed for diagnosing noise, vibration and harshness (NVH) issues in vehicles. It allows users to analyze signals from mechanical components and identify sources of unwanted noise and vibration that can be difficult to locate using conventional diagnostic methods. The kit includes one PicoBNC+ three-axis accelerometer and an NVH microphone, allowing vibration measurements at a selected point on the vehicle alongside noise analysis. It is particularly useful for diagnosing problems involving wheel bearings, engine and transmission mounts, driveshafts and other drivetrain components.
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 components based on assumptions, technicians can examine actual signals and relate them to the operation of individual vehicle components. Measurements can be performed during road tests or stationary testing, for example while running the engine at increased RPM.
The diagnostic process involves:
- Measurement – the accelerometer and microphone record vibrations and sounds generated by the vehicle.
- Identification – the software analyzes signal frequencies and helps associate them with specific components, such as wheels, the engine, bearings or the driveshaft.
- Confirmation – recorded data helps verify the suspected source of the problem and compare results with reference waveforms.
- 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 applies the appropriate measurement settings.
- Three-axis vibration measurement – the accelerometer records vibrations along the longitudinal, lateral and vertical axes.
- Direct PicoBNC+ connection – sensors connect directly to a compatible oscilloscope without requiring an additional interface module.
- No batteries required – PicoBNC+ NVH sensors are powered directly by the compatible oscilloscope.
- No additional activation required – the kit does not require registration or activation codes.
