The vibration machine currently used at the Satellite Technology Research Center(SaTReC) is the 1216VH electromagnetic vibration machine, 1216VH manufactured by LING. Electromagnetic vibration machine uses a power amplifier to operate the armature in an electromagnetic mechanism. This allows it to accurately conduct all necessary vibration tests. Satellites must be put through vibration testing before launching into Earth orbit and all vibration tests for the SaTReC developed STSAT-2 were conducted using this machine.
