Spectral Dynamics invented closed-loop digital vibration control and continues to lead with Panther — the next-generation control and analysis platform that combines precision, safety, and intuitive operation. Panther’s Random Control application builds on decades of engineering experience to deliver the industry’s most accurate, adaptive, and reliable random vibration control solution.
How Random Vibration Test Works
Panther’s Random Control provides true Gaussian random generation with precise adaptive equalization for rapid loop closure and stable control across all spectral ranges. Engineers can configure narrowband or broadband profiles, overlay live and stored data, and monitor real-time response with full-resolution spectral plots. The advanced control architecture ensures superior amplitude accuracy and repeatable test results even under complex dynamic conditions.
Advanced Random-on-Random Control Technology
- Real-time, gap-free streaming to the host disk for complete data integrity during testing.
- Multiple acquisition streams with independent sample rates for simultaneous capture of high-speed and low-speed data.
- Automated report generation with test summaries, control spectra, and limit profiles for easy documentation.
- Fully touch-screen compatible, optimized for Microsoft Surface and other Windows devices.
- Continuous monitoring of more than a dozen system parameters up to 25 times per second to ensure operator and equipment safety.
- Modern GTX interface provides intuitive setup, execution, and visualization for all random control parameters.
- Flexible configuration of control channels, profile shapes, and equalization parameters for diverse test environments.
- Integrated Library feature for instant access to setups, results, and comparison data without navigating file directories.
- Adaptive control algorithms deliver fast settling times and consistent performance across varying test conditions.
Easy Setup and Flexible Test Configuration
Panther’s GTX environment simplifies random vibration testing through logical workflow and immediate access to critical data. Users can quickly configure tests, access stored configurations, and compare results using the Library interface. Touch-enabled controls and real-time graphical updates streamline operation for both new and experienced engineers.
Safety Features for Random Vibration Test
Panther’s embedded safety system continuously verifies control limits, channel integrity, and loop stability. Independent watchdog circuits and digital interlocks protect both the hardware and the device under test. Automatic aborts and adaptive gain management ensure that even under fault conditions, the test remains within safe limits.
