Analysis Modules

Analysis modules for Oxygen streamline and automate the data analysis process. Order analysis is used to analyse the noise and vibration of machines with rotating parts. The sound level module is used for determining the time dependent sound pressure level according to IEC 61672 and IEC 651. Swept sine analysis is used to determine the transfer function and the bode diagram of a device under test that is stimulated by a shaker driven by a wave-generator replaying a sine sweep. Analysis modules can be used both in real time and in post processing.
