2 Cannel
NVH Analyzer
IEPE USB Interface


2 Channel NVH Analyzer Lite for IEPE sensors like vibration transducers and measurement microphones.

ROGA Instruments Plug.n.DAQ Lite is a compact IEPE sensor interface for Linux or Windows with 2 input channels. 

It offers the USB PC interface and requires no drivers for installation. 

The operating system such as LINUX or Windows recognizes the device as an external USB audio card.
