PicoDiagnostics NVH kits

Pico's products for Noise, Vibration and Harshness (NVH) testing give technicians the ability to identify and diagnose unwanted vibration and noise sources in a vehicle.

NVH and propshaft balancing

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 shop, 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.

If you don’t have a PicoScope Automotive oscilloscope, but you wish to use an NVH kit, you can invest in one of our Essentials kits and receive your choice of NVH Diagnostics kit complete with a 4 channel Automotive oscilloscope in a dedicated hard carry case.

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:

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