RogaDAQ2 NVH Analyzer & Recorder
2.2 Installation
Start your PC. Microsoft Windows ME, Windows 2000, Windows XP or above should be installed. These
operating systems do not require additional drivers. The RogaDAQ2 will be automatically detected and
installs it as USB-Audio-Device.
You may now use your RogaDAQ2 with any software supporting Windows PC soundcards.
3. Making Measurements
3.1 Scaling
The RogaDAQ2 outputs the analog signals as signed 16bit PCM data with a range of -32.768 to +32.767.
The maximum values represent the maximum input range (e.g. +32.767 = 5V;
-32.768 = -5V). The input range is defined as peak voltage, not rms.
Not all software applications detect the supported sampling rates properly. Please make sure to only
use the supported sampling rates as outlined in the specifications section.
3.3 Setup & Sensor supply
As first make sure that the RogaDAQ2 is enabled for two channel mode in the sound card properties:
