2304 PRECISION MULTI-AXIS POSITIONER (MAPS)

Positioning

The Model 2304 provides for precise yet flexible positioning of a test object, which can be mounted using fixtures available from ETS-Lindgren, custom design fixtures, or fixtures of your own design and manufacture. Objects can be rotated independently, in either/both theta and phi axes. Objects can be rotated 360 degrees (non-continuous) in either a clockwise or a counterclockwise direction, at variable speeds, and under program control using the optional software. 

Compatibility

The Model 2304 allows the height of the theta axis to be manually adjusted from 1.5 m to 1.7 m.  The adjustable height allows two different test methodologies to be implemented with a single positioner. For measurement methods requiring the test object to be rotated around a theta axis at 1.5 m height, use the default height of 1.5 m. For measurement methods requiring the bottom of the test object to be at a height of 1.5 m, the height of the theta axis can be adjusted upwards by 200 mm to a height of 1.7 m to accommodate test objects of up to a 40 cm cube.

Construction

The Model 2304 is covered with low reflective absorber material to minimize undesired reflections or distortion of RF fields. Control and motor units are contained in RF-shielded enclosures and are placed within the absorber covering. Signal lines from the controller to the connected PC are fiber optic and utilize an Ethernet-over-Fiber adapter at the PC.
