When considering vibration testing, companies face the choice between using external laboratories or establishing in-house capabilities. While outsourcing avoids capital costs and maintenance requirements, in-house testing provides superior scheduling control, eliminates transportation issues, and enhances security. Having dedicated equipment and trained personnel also facilitates rapid response to quality issues detected through vibration testing.

A complete vibration testing system typically includes four key components:

• Vibration Controller: The system's "brain" that compares measured signals to desired test profiles and computes necessary drive signals.
• Amplifier: Powers the system while monitoring all operational parameters for safety.
• Shaker: Provides the electromechanical force required for testing, with capacity for vertical and/or horizontal operation.
• Blower: Maintains proper cooling for the shaker system, with configurations varying by system size.
