• The isolation of the 770-5060 begins at 0.7 Hz, increasing rapidly to 40 dB beyond 10 Hz;
• The lack of any low frequency resonance means much better performance than with common passive damping approaches;
• The inherent stiffness of the 770-5090 imparts excellent directional + positional stability;

The outstanding isolation performance of the 770-5060 includes all six translational and rotational vibration modes. Active isolation systems offer a solution, which combines stiffness with a very short settling time. The most useful active systems employ inertial velocity in a feedback loop. (Inertial velocity can be measured for example by integration the signal from an accelerometer). A signal proportional to inertial velocity is very similar to a viscous damping force, but with the very important difference that the dumping is relative to an internal plane. So in contrast to the passive system, by increasing the damping, the system becomes "glued" to the inertial plane which by definition means the system is isolated from the enviroment.
