Arden’s MPX Modal Explorer makes measurement of Encircled Flux easy, and accurate, and it complies with international standards. But if you are measuring laser-based transmission light sources for multimode systems you may need to use a test jumper assembly and fiber shaker in order to avoid “speckle”. Industry standards (for example IEEE 802.3aq and FOTP– 203) call for the use of a mechanical fiber shaker.

MESA Vibration Control
-
MESA tests are specifically required when the unit under test is too heavy or too big and exceeds the capabilities of a single shaker. In a MESA application, multiple shakers provide excitation to the test specimen in a single axis. Different relations like same magnitude and phase for drives, different phase for drives, different magnitude and phase for drives, can be set for this MESA test.

Head Expanders
-
By increasing the mounting area of the shaker, multiple items can be tested at the same time, decreasing total test cycle time. In addition, with Guided Head Expanders, payloads with large foot prints can be safely mounted and tested on the shaker, minimizing the risk of damage to the shaker suspension system. Although many head expanders are resonant below 1000 Hz, average or extremal control allows operation to 2000 Hz.

Slip Table Assembly
CSTA Series
-
Unholtz-Dickie introduced the Combined Slip Table Assembly (CSTA) in the late 1960''s to meet the demand for positive mechanical alignment between the shaker and its companion horizontal slip table. The challenge was to achieve this positive, permanent alignment feature without requiring an expensive seismic mass in the vibration lab floor. The original CSTA design has been continuously improved over the years and has now become the industry standard for permanently aligned, integral reaction mass slip tables.
