Description

ETS-Lindgren's Multiple Axis Positioning Systems (MAPS) are designed to provide smooth rotation of a test object in both theta and phi axes. Typically, these units are used in systems that measure spherical antenna patterns and total effective radiated power of a wireless device. MAPS units are currently in operation at several CATL labs. Options for MAPS include the SAM Phantom (head or head and shoulders) and our Positioning Controller with GPIB. Three models, Light, Medium and Heavy Duty, are constructed with low reflective dielectric materials to minimize RF obstruction or distortion.

MAPS offer infinite position control of test objects. Objects can be rotated independently, in either/both theta and phi axes. Objects in the phi axis can be rotated in a continuous 360° clockwise/ counterclockwise direction, at variable speeds, under program control using the optional positioning controller. Objects in the theta axis can be rotated 360o with an optional positioning controller.

MAPS units have been carefully designed from the frame up to minimize EMI noise, and offer minimal physical obstruction to RF fields. Motor units enclosed in RF shielded enclosures and designed to be placed below the absorber. Signal Test lines from motor to the optional positioning controller is fiber optic. The MAPS unit is designed for structural integrity with low mass, low RF reflective dielectric materials.

Three models provide support for Light .45 kg (1 lb), Medium 11.3 kg (25 lb) or Heavy Duty 34.0 kg (75 lb) test objects. All MAPS units consist of a motor unit mounted below a rotating base, and an interchangeable mast unit.
