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.
