Description
The most powerful of our modal exciters, Types 4827 and 4828 offer precise and reliable operation in any modal testing scenario, including long-duration tests of outsized mechanical structures as well as applications with MISO and MISO configurations. Suitable for impulse, sine and random signals, they also have a wide frequency range (2 – 5000 Hz) and a peak-to-peak displacement of 50.8 mm (2 in).
