Dynamic Testing & Equipment's servo hydraulic vibration controller is specifically designed for the applications including; Packaging, Seismic, Automotive. The system is the result of the marriage of the DTE 3500 digital control system and the proven Vibration Research VR controller into one PC. Many application specific modules are available as options. Features include:

• 4Khz servo loop rate  With 10kHz coming soon!
• DTE's unique Overdrive feature for improving valve response. By using advanced simulation techniques DTE electronic engineers were able to develop a special valve driver which will significantly reduce the step response of standard flapper nozzle servo valves without risk of damaging the valve! 
• Digital control of all PIDF functions
• Digital control of Delta P stabilization
• Digital calibration and limits
• Integrated HCM and HPS control. 
• Ability to do wide range of wave forms with the ability to sequence these profiles:
  • Sine & Sine sweep
  • Sine on Sine
  • Sine on Random
  • Random on Random
  • Resonant Dwell Tracking
  • Shock Tests and SRS
  • Field Data Replication (playback of time history files)
• 241 Sample Rates form 100 Hz to 108,000 Hz.
• Extremely low noise floor  (<70nV/Hz)
• Incredible 26,000 Spectral Lines which is an Industry Maximum
• <-100 dB THD+N
• >130 dB dynamic Range
• Redundant calibration monitoring
