SignalForce® LE-1316-3 Electrodynamic Shaker


Vibration table at GTRI being used for LFPS controller electronics testing.
Frequency load envelope.

The shaker is a high performance/high efficiency air cooled shaker offering control capabilities for frequencies up to 3 kHz. It uses a rigid armature design combined with dual axial bearings to provide high quality dynamic response and cross axis restraint. The vibration table has supported CubeSat tests, and is capable of qualifying a containerized CubeSat in its dispenser to NASA General Environmental Verification Standard (GEVS) levels.
