NVH Diagnostics "Advanced" Kit in Foam Tray
This 3-axis NVH diagnostics kit is identical with the NVH Diagnostics "Starter" Kit PQ121, save that it isn't supplied with a carry case but in a foam tray for your toolbox!
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).
- 4-axis vibration and/or sound measurement at different locations in the vehicle
- Includes four 3-axis accelerometers and four 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.
Higher flexibility of the "Advanced" Kit
The equipment of this kit allows different combinations of vibration and/or noise measurements.
There are a maximum of four inputs of the (optional) Pico automotive oscilloscope available.
You can mount one 3D accelerometer anywhere in the vehicle and connect it to three inputs of the scope via an NVH interface. An additional 3-axis accelerometer or a microphone with a second NVH interface (whereof only one axis is used) can be connected to the fourth input.
It is also possible to mount accelerometers and/or microphones at four different locations in the vehicle, which are connected to the oscilloscope's inputs via four NVH interfaces (whereof only one axis is used at a time) and the four supplied colour-coded BNC connection cables.
This allows monitoring of the behavior of a vibration individually in all three directions or at four locations, thus improving the ability of the system to identify an existing problem and thus also the user to solve it.
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.
