Inertial shaker is a type of modal shaker. Like modal shakers, they are used in modal tests and provide excitation to the device under test.

But inertial shakers are not attached to the structure via a stinger instead, they are used by attaching directly to the test object. So, it is easier to apply and does not change the vibration response of the structure except for a small weight added to the structure.

Dynalabs inertial shakers are small, powerful and rugged. Also, their amplifiers are as small as the shakers, making them extremely easy to use.

Similar to the integrated amplifier Dynalabs shakers, amplifiers of inertial shakers have integrated signal generator which  can perform simple tests and trial for test setups.
