The Prosig NVH Starter system is a complete hardware and software bundle that provides a test engineer with everything they need to capture and analyze data from NVH & refinement tests. An ideal starting point for an engineer starting out in-vehicle NVH testing or other refinement scenarios.
System includes:
The Prosig NVH Pro System provides everything that the Starter System contains, but adds extra input channels, CAN-bus capability and more application software. The Prosig P8020 unit is configured with sixteen 24-bit analog inputs, dual CAN-bus inputs and a dedicated tacho input.
As well as the DATS.nvh software bundle the Pro system adds the Hammer Impact, Psychoacoustics and Structural Animation packages.
System includes:
The Prosig P8004 is an ultra portable, high quality, 24-bit data acquisition system. It is compact, rugged and has 4 analog inputs plus a dedicated tacho input.
The Prosig P8012 can hold up to 3 cards giving up to 24 analog input channels. The chassis is rugged and portable making it ideal for mobile applications of all kinds.
The Prosig P8020 has the same rugged, portable chassis as the others systems and is ideal for mobile or laboratory use where a higher channel count is needed.
