Digital Vibration Controller LEVCSUSB

  • Digital Vibration Controller LEVCSUSB has the full range of vibration test function,which can achieve random, sinusoidal sweep,resonance search and dwell, classical shock, sinusoidal-random, random-random on electrodynamic or hydraulic vibration table,and achieve narrowband random-sinusoidal,shock response spectrum control,transient simulation,road spectrum,etc simulated vibration test under random broadband.Windows 7/8/10 control software with friendly interface and convenient operation. At the same time, the system also provides perfect testing process management, data instructions and test report generation, making the test more convenient and reliable.

    Vibration control system adopts modular design and distributed data processing program to carry out the expansion of the channel and test function easily. Composed of32-bit high speed DSP processing structure, low noise circuit design technology, 24 bit A/D and D/A hardware, high-speed USB2.0 data communication circuit, the control software of the adaptive control algorithm id powerful, and improve the technical performance of vibrational control system to a new level.
