Waterfall/3D Graph/Color Map Spectrogram
A new analyzer program creates a three-dimensional plot from a set of data files or live data. It can display a 2D color map of a power spectral density (PSD) vs. time or a 3D waterfall graph/color map spectrogram of PSD vs. time.
Why 3D?
- Measure changes in vibration as load changes
- Identify resonant behavior over time or a fundamental bending mode frequency
- Seeking to maintain constant conditions
- Monitor shifts in resonant frequency

Full Waveform in FDR with Live Playback
Engineers use the Field Data Replication (FDR) software to reproduce a test environment on a shaker in the lab. In FDR, the user now has the option to view the complete acceleration waveform and the position of the time signal while the test is running.

Software Improvements
Memorize Notch/Boost for Level Changes
The VibrationVIEW Random software can boost/notch frequency ranges based on a response channel. Now, when the test level increases, the system maintains the overall shape of the output and accounts for the boost/notch, overriding the control when it reaches the next level.
Increased Lines of Resolution
The software now supports a maximum lines of resolution value of >104,000 with the VR10500. A greater lines of resolution value improves resonance control out to high levels.
Improved Out-of-Band Displacement Control
The out-of-band displacement control in Random is improved, so the low-frequency signal drops out significantly faster, resulting in less displacement on the shaker during these test types.
