1.0 Introduction
The ETS-Lindgren
Multi-Axis Positioning
System (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
azimuth and orthogonal
axes.
MAPS Models
Three models of MAPS are available. Each model provides a vertical support
column to support the Equipment Under Test (EUT).
MODEL 2110LIGHT DUTY MAPS
The Model 2110 light duty MAPS can accommodate EUT up to 0.45 kg (1.00 lb),
making it ideal for small devices.
Part Description Part Number
Model 2110 Light Duty MAPS
Includes:
Medium duty MAPS with optional SAM phantom head
• MAPS Turntable Assembly, part #111040
• Light Duty Mast Assembly, part #111046-NNNN
2110-NNNN
Specify height as –NNNN; for example, 72 inches is
–7200 and 59.5 inches is –5950
The MAPS includes a horizontal roll axis for mounting EUT. Each MAPS is built
according to the customer-specified height by reducing the vertical support
column to the appropriate length. The height of this axis must be specified when
ordering the unit. A motor drive at the base of the vertical support column, in
conjunction with the ETS-Lindgren Model 2090 Multi-Device Controller (or next
generation ETS-Lindgren controller, if applicable), controls the movement of the
unit.
Each MAPS is furnished with a 63-in (160-cm) diameter circular wood deck that
is bolted onto a motorized turntable. The deck has an opening for the vertical
support and access to the knobs that clamp the sliding carrier into a fixed
position.
The MAPS is equipped with two motor bases, one to control each rotational axis.
A 230 VAC 50 or 60 Hz single-phase receptacle is required to power each unit.
Current draw is less than 4 amps per motor base. The drive power for both
rotations is provided by the filtered 208–230 VAC, 50/60 Hz single-phase power
inside the chamber. Therefore, there is no need for power drive cables to
penetrate the shielded enclosure.
8 | Introduction
The following steps were taken to minimize potential radio frequency (RF)
obstruction or distortions of RF signals from low-directive wireless transmit
antennas:
•The use of minimum composite tube materials to fabricate the rotating shaft
and EUT mounts.
•RF cable connection to the EUT is made through a 1.2-inch hole provided in
the center of the roll axis shaft.
The resultant system test data shows virtually no RF interference from the
light duty MAPS.
Model 2090 Multi-Device Controller
The Model 2090
Multi-Device Controller
(or next generation
ETS-Lindgren
controller, if
applicable) directs the
motor drives for the
upper (phi or x) roll
axis and the rotation of
the turntable (theta or
y axis).
Masts
The x-axis motor drive mounts onto a rail system that is attached to the turntable.
This system is positioned on the turntable so that the x-axis centerline projects
through the center of the turntable. The rail system has a sliding carrier that
allows the vertical support assembly to be moved in or out, in a six-inch
(15.2 cm) range, from the center of the turntable. The sliding carrier enables the
movement of the EUT in or out in the same range.
To minimize any potential RF obstruction or distortion of RF signals from
low-directive wireless transmit antennas, each positioning system is provided
with fiber optic control lines that enable the I/O signal between the motor base
and the Model 2090 controller.
The MAPS mast is a dual-axis angular positioning system capable of rotating the
EUT on the center of both rotation axes with 360
the EUT on the center of both rotation axes. The angular accuracy is guaranteed
within ± 0.25
through the controller or measurement software

12 | Introduction
2.0 Maintenance
Before performing any maintenance, follow the safety
information in the ETS-Lindgren Product Information
Bulletin included with your shipment.
Do not perform maintenance while MAPS is operating.
During maintenance, disconnect power for safety.
WARRANT Y
Regular maintenance will prolong the serviceable life of the turntable. Follow the
recommended schedule and use the log on page 15 to keep a record of
maintenance performed.
If you have any questions concerning maintenance, contact ETS-Lindgren
Customer Service.
Routine Maintenance
Perform the following maintenance prior to each use:
•Visually inspect the Multi-Axis Positioning System (MAPS) and surrounding
absorber.
•Attempt to rotate each axis by hand. Excessive rotation may indicate a loose
drive component.
Only qualified individuals should conduct maintenance
inspections or perform maintenance on the MAPS.
During MAPS operation, listen for excessive or unusual noise.
Bi-Annual Maintenance
Perform bi-annual maintenance every six months after the MAPS is placed into
operation. Prior to maintenance, remove sufficient amounts of absorber to
provide access to the MAPS casters.
Grease the casters every six months or after every 2000 hours of operation. Use
a good quality bearing grease and a standard SAE grease gun to lubricate the
casters.
Maintenance | 13
Annual Maintenance
Perform the following maintenance every 12 months after the MAPS is placed
into service:
•Use a good quality bearing grease to lubricate the main bearing race. The
grease fittings are located inside the race, 90° apart, under the top. Three
discharges from the grease gun in each fitting are adequate.
•Use a good quality grease to lubricate the chain and sprocket of the chain
drive.
