PicoDiagnostics NVH (noise, vibration and harshness) kits are designed to provide 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.

Pico Technology Ltd. says 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. The files are simply saved to the laptop’s hard drive.

The PicoDiagnostics NVH kits use the PicoScope Automotive oscilloscopes and are available in a number of configurations. If a shop does not have a PicoScope Automotive oscilloscope, it can invest in one of Pico Technology’s “Essentials” kits and receive a NVH Diagnostics kit complete with a 4-channel Automotive oscilloscope in a dedicated hard carry case.

Below are just a few of the typical scenarios where an NVH kit can save a shop time and money, according to the company:

  • cabin vibrations at speed;
  • engine vibrations throughout the entire RPM range;
  • clutch judder or vibration;
  • transmission and bearing whine;
  • auxiliary drive noise;
  • brake judder;and
  • steering vibrations.
