a fixed end and an unsupported test region configured to receive a unit under test;

a separating slot separating the fixed end from the unsupported test region,

wherein a first mode natural frequency of the test fixture is based on a length of the separating slot;

a mounting slot proximal to the separating slot and extending through the fixed end;

wherein the mounting slot is configured to receive at least one fastener to couple the fixed end to a supporting structure, thereby cantilevering the test fixture.
