Introduction
ETS-Lindgren’s 2301 Type Precision Positioner is designed to perform automated 3-dimensional pattern
measurements. The positioner includes vertical support columns that will accommodate equipment under test (EUT)
up to 25 kg (55 lb).
The positioner is equipped with two motors (one Azimuth, one elevation), 208-230 VAC 50 or 60 Hz single phase.
An IEC receptacle is the standard power input. The IEC rocker switch illuminates red when in the ON position.
Current draw is fused at 6.3 A maximum. The motor drive, in conjunction with the provided command set, controls the
movement of the unit. 10 M (32.8 ft) ber-optic cable provided.
The 208-230 VAC motor power inlet is operated by an illuminated switch, and the inlet for the customer’s EUT is
operated by a non-illuminated switch. Labels on the top surface of the motor base indicate the location of each inlet.

Assembly and Installation
Pre-Installation Tasks
Pre-planning is essential for successful installation. Discuss requirements with your sales representative and request
dimensional drawings prior to construction of your site.
Before installing any components, follow the safety information in the ETS-Lindgren Product
Information Bulletin included with your shipment.
Ensure power is o󰀨 and base is secured before proceeding with installation.
Positioner Installation
Proper installation of the 2301 Precision Positioner unit directly a󰀨ects performance of the positioning system as well
as the accuracy of the test results.
1. Uncrate all parts. Check all parts for any shipping damage. Ensure a clear area is available to assemble the
positioner unit safely.
Do not discard packing material until the Turntable is fully assembled and correct operation is veried.
The 2301 Precision Positioner consists of:
• Variable speed turntable
• Lossy foam absorber to cover the positioner
• Vertical columns with tilt positioner
• Laser for aligning system
Customer provides RF, power, and control cabling to the top of the unit and to the EUT.
2. The center of rotation for the unit must intersect the line through the bore sight of the measurement antenna.
Use the included laser to verify alignment.
3. Place the unit so the positioner connections are easily accessible and located closest to available feed through
panels and power supply connections. Ensure the Model 2301 is connected to a power outlet that
supplies 208-230VAC 50/60Hz. Use the power cord provided with the Model 2301 to make this connection
to the system.
US shipments will include a NEMA type 6-15P electrical plug power cord.
International shipments will include a Schuko type electrical plug power cord.
The IEC power inlet assembly includes a lter and an illuminated power switch.
4. Connect the positioner to the included Ethernet-to-ber optic converter using the included dual ber optic cable
with type ST connections. The converter connects to the host computer via the included 0.9 m (3.0 ft) Cat5
Ethernet cable. Ensure the ber converter TX line is connected to the positioner RX input connector, and the
ber converter RX line is connected to the positioner TX output connector.

Electrical Installation
Electrical connection should only be performed by a qualied electrician and subject to location
electrical codes.
The Model 2301 Precision Positioner is designed to operate using 208-230 VAC single phase 50 or 60 Hz AC power.
The motor drive will not operate on a lower voltage, such as 110 VAC. The power inlet assembly has an integral 10 A
fuse, however the branch circuit supplying power to the motor drive must be protected from excess current according
to local electrical codes. Normal current draw for the drive is less than 6 A.
Ensure the distance from the mains power source is appropriate for the wire gauge used and that the wire gauge is
adequate for the motor load.
Using undersized wire gauge will result in a higher than expected voltage drop in the power
conductors, reduced starting torque, and potentially premature motor failure.
Prior to servicing the turntable, remove the power connection.
5. Loosen M6 bolts on the placeholder pipe.
6. Remove the two larger ones.
7. Take out the pipe.
8. Place the laser or antenna in place of the pipe.
9. The counterweight is adjustable via threaded rod it is mounted on.
10. The upper axis is limited to ±30°.
11. The turntable is limited to ±120°.
12. The separate, support bearing pinion drive is spring loaded. It eliminates slip between pinion and bearing.
13. Leveling feet can be adjusted in order to level unit.
