What is the difference between electrodynamic and servo-hydraulic shakers?

Electrodynamic shakers use a moving coil in a magnetic field and excel in high-frequency applications (up to 3,000 Hz+) like electronics testing. Servo-hydraulic shakers use hydraulic actuators and are ideal for high-force, large-displacement, low-frequency tests (typically below 500 Hz) on heavy structures like vehicles or airframes.
