The PicoDiagnostics NVH Kit form 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, Scantool 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
Kit contents
A BNC cable connects the interface box to an Automotive PicoScope (sold separately). A USB cable connects your PicoScope to PC or laptop to run the PicoDiagnostics software. A Separate J2534 Scantool or VCI can be used to provide RPM data, but is not supplied.
