Vibration controller. A vibration controller for driving a switching power amplifier used with an electrodynamic shaker providing a force of at least 2.2kN (495 lbf), such as LDS V850. Capable of a wide variety of test profiles, including random, swept-sine, classical shock, and resonance search, track and dwell.
Synthetic Impulse. The SIA-7 is capable of operating as three different types of ultrasonics systems. In effect, the SIA-7 is three boxes in one. The SIA-7 switches between modes at the click of a mouse. Ultrasonics systems employ methods including pulser receivers, continuous tone, tone burst systems and now Synthetic Impulse.
