ETS-Lindgren's Model 2122 Heavy Duty Multi-Axis Positioning System (MAPS) is designed to provide smooth rotation of a test object in both theta and phi axes. Typically the Model 2122 is used in systems that measure spherical antenna patterns and total effective radiated power of a wireless device, with MAPS units currently in operation at several CATL labs. 

Key Product Information


Positioning

Objects can be rotated independently, in either/both theta and phi axes. Objects in the phi axis can be rotated in a continuous 360 degrees clockwise/ counterclockwise direction, at variable speeds, under program control using the optional positioning controller. Objects in the theta axis can be rotated 360 degrees (non-continuous) with an optional positioning controller.

 

Construction

The model 2122 is constructed with low reflective dielectric materials to minimize RF obstruction or distortion, and was designed to minimize EMI noise and offer minimal physical obstruction to RF fields. Motor units contained in RF-shielded enclosures and are designed to be placed below the absorber. Signal lines from motor to the optional positioning controller are fiber optic.
