FFT Analyzer for
Vibration Measurement


NVH FFT Analyzer

RogaDAQ2 Digital USB Sensor Interface AC,DC, IEPE DAQ

The RogaDAQ2 USB DAQ is developed for highly accurate measurements in the T&M and also for NVH measurements. This USB Front End is optimized for noise and vibration measurements with 2 channel IEPE (ICP®) sensor supply.

Main feature of the RogaDAQ2 is the driver and free software concept. Special drivers are not needed ; the unit is detected by the PC as standard Soundcard.

Measurement programs like ArtemiS, Audacity, DASYLab, LabView, Levelcheck, MatLab, PAK by Müller BBM, RogaREC, Smaart works directly in real time.

Linux – Ubuntu

with Plug.n.DAQ & RogaDAQ2

Ane de Jong, kindly provides us with his Linux implementation for reading 2 channel Digital IEPE – USB Sensor Conditioner data from Plug.n.DAQ series and RogaDAQ2, using Linux ALSA sound system.

Here you can find the code library for Acoustic Signal Processing
