SIGNAL CONDITIONERS To support the use of its sensors in large scale testing, ENDEVCO has developed several generations of signal conditioner systems. Until recently, a state-of-the-art vibration laboratory set up consisted of a rack of manually controlled signal conditioners. These signal conditioners have manually controlled switches and knobs, to set full scale ranges, sensitivity and filter corners and the set up information is recorded by hand. -
