LMS Test.Lab Time Data Acquisition and Processing provides a powerful tool for recording time data in laboratory and field conditions up to 80kHz effective bandwidth. The system can record continuous time data while monitoring online and in real-time user-configurable processing functions, including order sections or any function important for noise and vibration applications. All signal conditioning provided by LMS SCADAS front-ends is supported.
LMS Test.Lab Time Data Acquisition and Processing writes time histories for all channels directly to the PC hard disc. The resulting time data files have no physical size limitations and contain all dynamic and static channels as well as rpm-time traces for all tacho channels and overload information for each individual channel. Highly responsive level indicators provide an instantaneous overview of all channel levels, and provide high or low alarming capabilities on detected peak levels. Online and off-line processing and visualization capabilities include instantaneous or averaged frequency spectra, time data, octave data, order and frequency sections, overall levels, waterfall and color map displays. Highest priority is given to throughput data and level detection, while displays show the latest processed data.
Once the data is acquired, it is immediately ready for visualization and post-processing. The LMS Test.Lab interface helps users interactively select specific time segments, perform a wide range of editing operations, or batch process all channels, even from different measurement runs.
The solution permits interactive time data editing and provides a broad range of processing functions like spectrum, autopower, crosspower and FRF, order sections, frequency sections, octave maps, equivalent loudness, cepstrum and Hilbert transform, or zero-phase LP-HP-BP-BS and (trackable) Notch filtering.
