A vibration testing apparatus comprises a first mooring bar coupled to the base; a second mooring bar coupled to the base such that the second mooring bar is disposed away from and faces the first mooring bar to define a space between the first and second mooring bars; a first strap comprising a first end secured to the first mooring bar, and a second strap comprising a first end secured to the first mooring bar. A second end of each of the first and second straps may be secured to the second mooring bar such that the first and second straps span the space between the first and second mooring bars and such that a tension on at least one of the first and second strap is controllable.
1. An apparatus for vibration testing an electronic device, comprising: a base comprising a mechanism for securing the base to a shaker table that is configured to subject the electronic device to vibrations or shocks;a first mooring bar coupled to the base;a second mooring bar coupled to the base s
1. An apparatus for vibration testing an electronic device, comprising: a base comprising a mechanism for securing the base to a shaker table that is configured to subject the electronic device to vibrations or shocks;a first mooring bar coupled to the base;a second mooring bar coupled to the base such that the second mooring bar is disposed away from and faces the first mooring bar to define a space that is configured to accommodate the electronic device to be vibration tested between the first and second mooring bars;a first strap comprising a first end secured to the first mooring bar, anda second strap comprising a first end secured to the first mooring bar, a second end of each of the first and second straps being secured to the second mooring bar such that the first and second straps span the space between the first and second mooring bars to secure the electronic device to the base at least during the vibration testing and such that a tension exerted on at least one of the first and second strap is controllable, to adjustably clamp the electronic device to be vibration tested to the base. 2. The apparatus of claim 1, further comprising: first and second spacers configured to be disposed such that at least a portion thereof is disposed between the base and the first strap, andthird and fourth spacers configured to be disposed such that at least a portion thereof is disposed between the base and the second strap. 3. The apparatus of claim 2, wherein the first and second spacers each define a slot configured to enable the first strap to fit therethrough and wherein the third and fourth spacers each define a slot configured to enable the second strap to fit therethrough. 4. The apparatus of claim 1, wherein the base is configured to be secured to a shaker table. 5. The apparatus of claim 1, wherein the base comprises a surface of the shaker table. 6. The apparatus of claim 1, wherein the second mooring bar is adjustably coupled to the base to enable the tension on at least one of the first and second straps to be controlled according to a position of the second mooring bar. 7. The apparatus of claim 6, wherein the position of the second mooring bar is configured to be adjustable in a direction that is substantially perpendicular to the base to enable the tension on at least one of the first and second straps to be controlled. 8. The apparatus of claim 6, wherein the position of the second mooring bar is configured to adjustable in a direction that is substantially parallel to the base to enable the tension on at least one of the first and second straps to be controlled. 9. The apparatus of claim 1, wherein the second mooring bar is configured to be movable to vary the space between the first and second mooring bars and is configured to be movable to adjust the tension on at least one of the first and second straps. 10. The apparatus of claim 1, further comprising at least one load cell configured to generate a signal that is based upon the tension on at least one of the first and second straps. 11. The apparatus of claim 1, wherein the electronic device comprises a laptop computer and wherein the first and second mooring bars are adjustably coupled to the base to enable the laptop computer to be disposed in the space therebetween and wherein the tension on at least one of the first and second straps is configured to be adjustable such that the laptop computer is clamped to the base. 12. The apparatus of claim 1, wherein the electronic device comprises an external disk drive and wherein the first and second mooring bars are adjustably coupled to the base to enable the external disk drive to be disposed in the space therebetween and wherein the tension on at least one of the first and second straps is configured to be adjustable such that the external disk drive is clamped to the base. 13. A method of vibration testing an electronic device, comprising: fitting the electronic device between a base and first and second straps;adjusting a tension on at least one of the first and second straps to adjustably clamp the electronic device between the base and the first and second straps;securing the base to a shaker table;turning the shaker table on to subject the electronic device to vibrations or shocks, andcharacterizing an operation of the electronic device while the electronic device is subjected to the vibrations or shocks. 14. The method of claim 13, wherein the first and second straps are coupled to a mooring bar adjustably coupled to the base and wherein adjusting the tension on at least one of the first and second straps comprises moving the mooring bar. 15. The method of claim 14, wherein moving the mooring bar comprises moving the mooring bar in a direction substantially perpendicular to the base. 16. The method of claim 14, wherein moving the mooring bar comprises moving the mooring bar in a direction substantially parallel to the base. 17. The method of claim 14, wherein a first end of each of the first and second straps is secured near one end of the base, wherein a second end of each of the first and second straps is secured to the mooring bar near a second end of the base, andwherein adjusting the tension comprises moving the mooring bar. 18. The method of claim 14, further comprising measuring the tension on at least one of the first and second straps. 19. The method of claim 14, wherein the electronic device comprises a disk drive and wherein characterizing the operation of the disk drive comprises measuring a Position Error Signal (PES) of the disk drive. 20. The method of claim 13, wherein first ends of the first and second straps are coupled to a first mooring bar that is adjustably coupled to the base, wherein second ends of the first and second straps are coupled to a second mooring bar that is adjustably coupled to the base, andwherein fitting the electronic device comprises adjusting a position of the first and second mooring bars on the base to adjust a space therebetween.
