Abstract
A test ramp is disclosed comprising a plurality of planar surfaces, wherein each planar surface comprises at least one impediment. Each impediment is offset along a planar axis from the other impediments, and each impediment is operable to contact part of a respective actuator arm of a disk drive in order to excite a microactuator coupled to the actuator arm.
