Employ an advanced analysis of one or multiple waveforms with features such as resampling, filtering, and advanced graphing functions (PSD, transfer function, etc.).Download Demo All Software Features
Analyze time-waveform data in the frequency domain with the following advanced graphing functions:
Fast Fourier transform (FFT) and power spectral density (PSD) mathematics are powerful tools for analyzing the characteristics of a waveform. There are also several mathematic functions that help to explain the relationships between two or more waveforms.
The “Mathematics for Understanding Waveform Relationships” VRU course introduces three functions for comparing data: transfer function, correlation, and cross-spectral density.
Resampling changes the sample rate to user specifications on a time waveform.
Filtering removes frequency components from a time waveform. They can filter out, accept, or boost frequency components. Filter options include high-pass, low-pass, and bandpass filters.
General Purpose FIR Filters
If your tests require the following, then you may need an FIR filter:
In addition to advanced analysis tools, the ObserVIEW Advanced license includes Multimedia Sync, Octave Analysis, and Math Traces.
Multimedia Sync opens a video file(s) and syncs it with the time of the recording. Then, view the video and data playback at the same and extract images/data for a report. You can also add other media files such as additional video files and audio files after the player is open. LEARN MORE.
Octave Analysis generates octave bands with an 8th-order filter to meet IEC 61260-1 Class 1 filter specifications. It performs filter-based analysis and can apply A and C frequency weighting, linear and exponential averaging, and peak hold. LEARN MORE.
Math Traces is a free entry field that builds a trace using existing trace data operated on by functions and operators.
