INTRODUCTION
The ETS-Lindgren Multi Axis Positioning System (MAPS™) is available in three types for light, medium, and heavy
duty:
2112-NNNN Light duty DD MAPS
2117-NNNN Medium duty DD MAPS
2122-NNNN Heavy duty DD MAPS
The MAPS is designed to perform measurements of spherical antenna patterns as well as total and effective isotropic
radiated power of wireless devices.
The MAPS provides independent rotation in both horizontal and vertical axes. In addition, the MAPS rotates
continuously around the vertical axis.
The MAPS is built according to the customer specified height; the height of this axis must be specified when placing the
order. A motor drive at the base of the vertical support column controls the movement of the MAPS, in conjunction with
a positioning controller (sold separately), such as the EMCenter™ Modular RF Platform.
To minimize potential radio frequency (RF) obstruction or distortions of RF signals from low directive wireless transmit
antennas, the following features were implemented into the design of the MAPS:
• The use of minimum composite tube materials to fabricate the rotating shaft and mounts for Equipment Under
Test (EUT).
• RF cable connection to the EUT is made through a hole provided in the center of the roll axis shaft.

The base model number are 2112, 2117 and 2122. A
suffix is added to indicate the height above the floor
for the phi axis in inches.
For example, Model 2117-6000 is a medium duty
MAPS with a phi axis rotation height of 60.00 inches.
