Pico 3-axis NVH Diagnostic Kit (in foam)

The cost-effective tool for real-time NVH diagnosis

  • Includes a 3-axis accelerometer and a microphone
  • Full screen, high-resolution results are presented clearly and accurately
  • No external memory required – saves directly to laptop or PC
  • Record up to 500 seconds of data
  • Automatic analysis
  • Detects multiple vehicle vibrations
  • Customer report function
  • Plugs into your Automotive PicoScope® (sold separately)

Please note: The NVH kit from Pico Technology only works with our Automotive PicoScopes, and requires an unlock key in order to allow your PicoScope to work with the NVH software. Once you receive your NVH kit, please follow the instructions within the kit to obtain your unique key. This unlock key is limited to one PicoScope Automotive scope and is not transferable. Supported PicoScope models are 4425, 4225, 4423, 4223. RPM data may be taken from a J2534 Scan Tool or VCI (not included).



The PicoDiagnostics NVH Kit from Pico Technology is the cost-effective answer to the many NVH problems facing technicians today. Providing real-time diagnosis to the technician in the form of either: a bar graph, a frequency chart, a 3D frequency chart, RPM order or road speed view. The ability to start the recording before a road test, and play back the recording for analysis on your return, ensures that driver attention remains on the road. Saving the recordings couldn’t be simpler: much like our other automotive software you simply save the file to your laptop’s hard drive.

The PicoDiagnostics NVH kit makes use of the PicoScope 4000 Series Automotive oscilloscope, and comes complete with everything you need (J2534 Scan Tool or VCI not supplied). 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 4000 Series Automotive oscilloscope, you’re halfway there.

What's in the pack?

The NVH interface unit connects to your Automotive PicoScope (sold separately) via a BNC cable, and the PicoScope is connected by USB to a PC or laptop running the PicoDiagnostics software. A separate J2534 Scan Tool or VCI (not supplied) can be used to provide RPM data.

Your PicoDiagnostics NVH Kit contains the following items:

  • TA259 3-output NVH interface unit
  • TA096 Mounting magnet for accelerometer
  • TA143 MEMS accelerometer
  • TA243 Cable: insulated BNC to BNC 0.5 m blue
  • TA244 Cable: insulated BNC to BNC 0.5 m red
  • TA245 Cable: insulated BNC to BNC 0.5 m green
  • TA144 Microphone for NVH kit
  • TA145 Sensor extension cable for NVH interface unit
  • PA110 Foam tray for NVH kit

Typical uses

Customer complaints surrounding noise/vibration are subjective at best and present technicians with a challenge before diagnosis and rectification begins. Applying the NVH kit to the vehicle will allow the technician 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 analysed and compared to previous captures or against donor vehicles. Often what is perceived by the customer to be a "problem" vibration is in fact a characteristic. Now you can present and compare objective data with test results from donor vehicles to reassure your customer that all is well. Alternatively, comparing data may highlight a problem within the vehicle allowing the technician to proceed to a repair with confidence supported by measurements taken. Below are just a few of the typical scenarios where the NVH kit can save time and money:

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