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
