Model 2090 Multi-Device Controller
INTRODUCTION
The Model 2090 Multi-Device Positioning Controller is
designed for use with ETS-Lindgren positioning devices
such as antenna towers, turntables, reverberation paddles,
multi-axis positioners, etc. to accomplish a variety of tests
for EMC compliance, antenna pattern measurements, and
more.
The Controller allows the user to synchronize the
simultaneous, yet independent movement of two primary
devices such as towers or turntables in either manual or
remote GPIB modes while controlling the on/off operation
of up to four auxiliary devices.
Each primary device is interfaced to the Model 2090
through a bi-directional fiber optic interface using a
proprietary command protocol. Auxiliary devices use a
single-pole double-throw RF relay to control simple on/off
operation. The connection type is SMA.
The front panel of the Model 2090 provides the interface
for two separate and complete device controllers, each with
identical displays and function keys. The function keys let
the user configure device specific parameters, adjust limit
and position settings, and control device motion. Numeric
displays and status indicators are provided for each device
interface to show positioning and operational information,
as well as device parameter settings. In addition to the two
primary device interfaces, there is an auxiliary control
interface for four auxiliary devices. This interface provides
©ETS-Lindgren, April 2006 11
Revision G– P#399199
Introduction Model 2090 Multi-Device Controller
keys and indicators to allow the user to manually toggle the
auxiliary devices on or off.
Control of all devices may be accomplished either in the
manual or remote modes through the use of the GPIB
(IEEE 488 standard interface bus) port located on the rear
panel. Each primary device is identified by a unique GPIB
address that the controller recognizes, allowing each
positioning device to function as a separate device on the
GPIB bus.
APPLICATIONS
RADIATED EMISSIONS TESTING
The Model 2090 is used to control ETS-Lindgren towers
and turntables during manual or fully automated radiated
emissions testing. The controller is capable of controlling
the tower height scan and antenna polarization functions
and the turntable rotation function from the operator's
station during remotely controlled or manual
measurements. This capability satisfies the technical
measurement requirement to search in azimuth and over a
specified height range to detect the maximum of the signal
sourced in the equipment under test.
SITE ATTENUATION MEASUREMENTS
The Model 2090 allows for the remote control of the height
search of all ETS-Lindgren towers during site attenuation
testing. With this capability, the user can maximize the
signal level detected at each measurement frequency within
the required height search range.

Revision G– P# 399199
Model 2090 Multi-Device Controller
PATTERN ANALYSIS
With the Model 2090, the user can have manual or
automated control of the turntable rotation function or the
ortho (elevation) and azimuth functions of a Multi-Axis
Positioning System (MAPS) from an operator's station
during antenna pattern measurement.
REVERBERATION CHAMBERS
The Model 2090 can provide precise step control of all
ETS-Lindgren reverberation paddles for mode-tuned
operation, or continuous rotation variable speed control for
mode-stirred operation.
FEATURES
FIBER OPTIC INPUT/OUTPUT LINES
• Eliminate unwanted RF signals generated over wire
cables.
• Each primary device cable contains two fiber optic lines
(transmit/receive).
• Each auxiliary device cable contains one fiber optic line
(transmit only).
• Fiber optic connectors (device and auxiliary) on the
back panel are metal ST connectors that are reliable and
easy to use.
MULTI-DEVICE CONTROL
• Duplicate front panel controls permit simultaneous and
synchronized control of two primary devices and four
auxiliary devices in both manual and remote modes.

POLARIZATION/FLOAT/SPEED key – This key has a
variety of behaviors depending on the attached primary
device type:
a. For towers, pressing this key toggles the tower boom
between horizontal and vertical polarization when the
display shows the current position; and toggles the
display between horizontal and vertical limit displays
when showing an upper or lower limit.
b. For air-flotation turntables, pressing this key floats or
lowers the turntable on its air cushions. The turntable
cannot be dropped while in motion.
c. For two speed turntables, pressing this key toggles the
turntable between fast and slow speed.
d. For standard variable speed turntables, pressing this key
advances the selected speed setting to the next preset
speed selection.
HOR/UP/FAST indicator – This indicator has a variety of
behaviors depending on the attached primary device type:
a. For towers, this indicator lights solid to indicate that the
tower is polarized horizontally. This indicates the
status of the polarization solenoid only, and may or may
not reflect the actual position of the tower’s cross boom
at any given instant. This indicator flashes to indicate
that the display is showing the upper or lower limit for
the horizontal polarization, while the tower is still
polarized vertically.

b. For air-flotation turntables, this indicator lights solid to
show that the air flotation solenoid has been activated.
c. For two speed turntables, this indicator lights solid to
show that the turntable motor is set to high speed.
d. For standard variable speed turntables, this indicator
lights in a binary fashion with the VERT/DN/SLOW
indicator to represent the least significant bits of the
current speed selection. See the section on
“OPERATION” for more information on this display.
VERT/DN/SLOW indicator – This indicator has a variety
of behaviors depending on the attached primary device
type:
e. For towers, this indicator lights solid to indicate that the
tower is polarized vertically. This indicates the status
of the polarization solenoid only, and may or may not
reflect the actual position of the tower’s cross boom at
any given instant. This indicator flashes to indicate that
the display is showing the upper or lower limit for the
vertical polarization, while the tower is still polarized
horizontally.
f. For air-flotation turntables, this indicator lights solid to
show that the air flotation solenoid has been deactivated.
g. For two speed turntables, this indicator lights solid to
show that the turntable motor is set to low speed.
h. For standard variable speed turntables, this indicator
lights in a binary fashion with the HOR/UP/FAST
indicator to represent the least significant bits of the
current speed selection. See the section on
“OPERATION” for more information on this display.
