Designed for Reliable and Accurate Vibration Control

In vibration testing laboratories, control accuracy, system responsiveness, and operational safety directly determine test validity and equipment protection. The VT Series Vibration Controller is developed to meet these critical demands, combining over 20 years of engineering experience with a proven global user base of more than 10,000 customers.

Built on a distributed control architecture, the controller separates real-time control from the host PC, ensuring stable closed-loop performance even in complex and long-duration tests.

• DSP-based closed-loop control architecture
  Ensures real-time response and high reliability by keeping critical control tasks independent from the PC environment.

• 24-bit high-resolution ADC on every input channel
  Combined with low-noise hardware design and advanced analog and digital anti-aliasing filters (up to 160 dB/Oct) for precise signal acquisition.

Comprehensive Test Functions for Diverse Applications

Modern vibration tests often require multiple excitation types and combined loading conditions. The VT Series supports a wide range of standard and advanced vibration control functions to adapt to different industries and test objectives.

• 12 standard vibration control functions, including:
  Sine, Resonance Search & Dwell, Random, Sine-on-Random, Random-on-Random, Multi-Sine, Classical Shock, Shock Response Spectrum (SRS), Transient Shock (Seismic Wave Simulation), Road Profile Simulation, and Random Shock.

• Specialized advanced functions
  Including Kurtosis Control, Channel Notching Control, Step Sine, Shock SRS Analysis, and full TEDS sensor support to address complex and customized testing requirements.

High Performance for Demanding Test Standards

To meet increasingly stringent test specifications, the VT Series delivers outstanding dynamic range and frequency coverage.

• Random control dynamic range > 90 dB

• Sine control frequency up to 10,000 Hz

• Random control frequency up to 18,750 Hz

• Up to 6,400 spectral lines for random analysis

These capabilities allow engineers to perform high-fidelity vibration tests with confidence and repeatability.

Flexible and Convenient Input Configuration

Test setups often involve different sensor types and frequent reconfiguration. The VT Series is designed to simplify signal connection and conditioning.

• Hot-pluggable BNC input channels for fast setup

• Independent voltage and charge amplifiers per channel

• Support for IEPE, voltage, charge, and TEDS sensors
  Ensuring compatibility with a wide range of transducers without external signal conditioning.

Advanced Safety Protection for Equipment and Personnel

High-energy vibration tests carry inherent risks. The VT Series integrates more than 20 safety monitoring and interlock mechanisms to protect operators, test specimens, and shaker systems.

• Open-loop detection, RMS interruption, spectrum limit checking, drive and shaker protection, emergency stop, and more

• Independent RMS and peak interruption thresholds for each channel
  Immediately stops the test when limits are exceeded, minimizing the risk of system or specimen damage.

User-Friendly Operation and Professional Reporting

Efficiency in daily testing operations is as important as performance. The VT Series software is designed for ease of use without compromising professional functionality.

• Windows-based graphical user interface, intuitive and easy to learn

• Customizable display windows, cursors, fonts, and colors

• AVD display for sine tests, showing acceleration, velocity, and displacement simultaneously

• Automatic test report generation in Word, PDF, or direct print formats

• Gigabit Ethernet and USB communication for fast and stable data transfer
