NVH Diagnostics "Standard" Kit in a Carry Case
Please note: The NVH kit from Pico Technology only works with our Automotive PicoScopes, and requires an unlock code in order to allow your PicoScope to work with the NVH software. This unlock key is limited to one PicoScope Automotive scope and is not transferable. Supported PicoScope models are 4425 and 4423. RPM data may be taken from a J2534 Scan Tool or VCI (not included).
- 3-axis vibration measurement plus 1 axis for vibration or sound at another location in the same vehicle
- Includes two 3-axis accelerometers and two microphones
- 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)
The PicoDiagnostics NVH Kit from Pico Technology is the cost-effective answer to the many NVH (noise, vibration, harshness) 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 NVH unit connects its three outputs to three inputs of a 4-channel PicoScope via the supplied colour-coded BNC connecting cables.
This allows to monitor the behaviour of a vibration in each axis individually and hence improves the system's ability to identify and hence the user's ability to fix a given problem. For some problems this ability to look at all 3 axes independently is key to identifying a problem.
With this 4-axis version a further 3-axis accelerometer (whereof only one axis used) or a microphone is connected to the fourth oscilloscope input in order to detect vibrations or noise at another location in the same vehicle.
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 a PicoScope 4000 Series Automotive oscilloscope (not supplied), and comes complete with everything you need. 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.
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

What’s in the pack?
The NVH interface units connect to your Automotive PicoScope (sold separately) via the four BNC cables, 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.
A USB cable connects your PicoScope oscilloscope with the PC or laptop computer in order then to start the PicoDiagnostics software.
