Random Vibration Shaker Table

A random test is conducted by using closedloop feedback to introduce the random vibration ofingle location for example the shaker table to exhibitesired psd. the psd demonstrates how hard the shaker is working, but it doesnt give any direct information regarding the forces experienced in the dut.
