Product Overview
Dynamic signal acquisition systems capture and analyze time-varying signals from sensors monitoring vibration, shock, acoustic emissions, and other dynamic phenomena. These systems combine high-speed analog-to-digital conversion, anti-aliasing filters, and sophisticated signal processing algorithms to extract meaningful information from complex dynamic events. Bridgent Technology's dynamic acquisition systems offer sampling rates from 100 kHz to several MHz per channel, enabling accurate capture of high-frequency transients and detailed frequency domain analysis.
Modern dynamic signal analyzers integrate multiple measurement capabilities including FFT analysis, order tracking, modal analysis, and sound intensity mapping. Synchronous multi-channel acquisition with precise timing ensures accurate phase relationships between measurement points, essential for operational deflection shape analysis and transfer function measurements. Advanced triggering and pre-trigger capture capabilities ensure critical transient events are captured with sufficient context for analysis.
The systems feature flexible input conditioning with programmable gain, AC/DC coupling, and IEPE sensor excitation. Built-in calibration and sensor database management streamline setup and ensure measurement accuracy. Real-time processing capabilities enable immediate feedback during testing, while comprehensive post-processing tools support detailed analysis of recorded data.
