Field Data Replication
Panther Field Data Replication Control delivers precision and performance in time-domain waveform reproduction. Built on Spectral Dynamics' heritage as the inventor of closed-loop digital vibration control, Panther combines advanced adaptive algorithms, comprehensive safety, and intuitive operation to provide trusted results, every time. Using advanced digital filtering, adaptive feedback, and the immense computational capability of the Panther platform, engineers can accurately duplicate complex field environments for verification, durability, and qualification testing. When quality of data is important, Panther sets the standard.
How Replication Works
Replication Control reproduces recorded time-domain waveforms captured during real-world events such as road profiles, aircraft takeoff, or launch vibrations. Using adaptive control and Spectral Dynamics' proprietary digital filtering, Panther ensures accurate reproduction of both amplitude and phase characteristics of the original waveform without requiring manual iteration. Real-time feedback from all input channels is analyzed continuously to maintain precise control, even under nonlinear or time-varying test conditions.
Gap-free streaming ensures that long-duration recordings can be replayed directly from disk in real time, with all data archived for post-test analysis. Panther's hardware-synchronized acquisition provides phase coherence better than one degree between all channels up to 100 kHz, guaranteeing time alignment and high-fidelity waveform reconstruction.
Ease of Use & Flexibility
Panther's Replication application simplifies even the most complex test setups. Through the Library feature, users can instantly access saved setups, data, and reports without navigating complex file paths. With an intuitive graphical interface and integrated Library access, users can configure, monitor, and replay data from previous tests quickly and confidently. The interface supports touch-screen operation and customizable layouts for both production and R&D environments. Easily and quickly compare data from different channels and different test runs. Panther's modern, touch-friendly interface makes operation fast and intuitive, for engineers at all experience levels.
