Digital Vibration Controller Functions
Random Control
Utilizes transfer function equalization with user-defined power spectrum diagrams. Continuously outputs Gaussian random signals for real-time, accurate multi-channel closed-loop control. Built-in adaptive control algorithms quickly respond to system nonlinearities, resonant frequency, and load changes.
- Frequency range: 0-4680Hz (extendable to 18750Hz)
- Resolution: 100, 200, 400, 800, 1600, 3200 spectral lines
- Control power range: >90dB
- Control strategy: single channel control, weighted average, maximum value, minimum value

Sine Control
Provides high-quality sine and sine sweep signals with precise amplitude control. Configure dwell magnitude, dwell frequency, and duration by time or number of cycles.
- Frequency range: 1Hz-4680Hz (expandable to 10000Hz)
- Closed loop time: 5 mS
- Harmonic distortion: <-100dB
- Frequency sweep modes: linear (0-6000 Hz/min) and logarithmic (0-100 Oct/min)
- Sweep direction: up and down
- Sweep duration: configurable by number of sweeps or test times

Classical Shock
Employs transfer function equalization method supporting various waveform types including half sine wave, bell wave, rectangular wave, trapezoidal wave, front peak sawtooth wave, back peak sawtooth wave, and triangular wave. Custom pulse peak values can be input as needed.
- Pulse duration: 0.5 to 3,000mS
- Maximum analysis bandwidth: 22000Hz
- Frame size: up to 16384
- Compliance: MIL-STD-810 (US military standard), ISO standard, user-defined interrupt control limits
