Exciter Box Description The Exciter-Box allows an excitation signal to be applied to the TS-Isolation System so that the system may be used as a shaker in any direction. Connect the T-Box to the rear of the TS using a D-Sub 15M-F cable. No separate power supply is required. Different excitation directions can be selected by the Mode Switch.
