1.0 Introduction
For flexible configuration of an EMC test facility and fully-automated testing, the
ETS-Lindgren EMCenter™ Modular RF Platform provides space for up to
seven plug-in cards in a 3U, 19-inch rack mount enclosure. The EMCenter can
also be used as a desktop unit.
The EMCenter is available in the following configurations:
 Model 7000-001: 7-slot EMCenter Modular RF Platform
 Model 7000-010: 7-slot EMCenter Modular RF Platform with GPIB
 Model 7000-011: 2-slot EMCenter Modular RF Platform with GPIB
The slots can contain a user-defined combination of these ETS-Lindgren cards:
EMSwitch™, EMPower™, EMControl™, and EMSense™. When installed, each
card is automatically recognized, initialized, and ready for use. For more
information on the cards, see EMCenter Plug-In Cards (Optional) on page 8.
The EMCenter is configured and controlled using the 7-in widescreen color
thin-film transistor (TFT) touchscreen on the front panel. Additionally, the
EMCenter may be controlled from a computer using these software products:
 ETS-Lindgren TILE!™ (Totally Integrated Laboratory Environment)
 ETS-Lindgren EMQuest™ Data Acquisition and Analysis Software
 Other test automation software

8Introduction www.ets-lindgren.com
The EMCenter contains a Vortex-embedded main processor to control all cards
and to interface with the user and/or an external computer. The operating system
is Linux-based, providing a stable operating environment, fast startup time, and
high performance. All embedded software is stored in flash, making it easy to
upgrade to new versions and future functionality.
EMCenter Plug-In Cards (Optional)
EMS WITCH RF S WITCH P LUG -I N C ARD
EMSwitch is a general purpose multi-channel switch matrix used to switch the RF
path of equipment for RF measurement applications, including immunity,

EMControl is a versatile positioner controller
which enables you to synchronize the
simultaneous movements of up to two
ETS-Lindgren positioning devices
(for example, towers or turntables) and the
on/off operation of an additional auxiliary
device, such as a LISN or EUT.
EMS ENSE EMF P ROBE P LUG -I N C ARD
The EMSense card provides an interface for
ETS-Lindgren battery-powered EMC field
probes. Each EMSense card can support
one probe.

14 Maintenance www.ets-lindgren.com
Maintenance of Fiber Optics
Fiber optic connectors and cables can be damaged from airborne particles,
humidity and moisture, oils from the human body, and debris from the connectors
they plug into. Always handle connectors and cables with care, using the
following guidelines.
Before performing any maintenance, disconnect
the fiber optic cables from the unit and turn off
power.
When disconnecting fiber optic cables, apply the
included dust caps to the ends to maintain their
integrity.
Before connecting fiber optic cables, clean the
connector tips and in-line connectors.
Before attaching in-line connectors, clean them
with moisture-free compressed air.
Failure to perform these tasks may result in
damage to the fiber optic connectors or cables.
Service Procedures
For the steps to return a system or system component to ETS-Lindgren for
service, see the Product Information Bulletin included with your shipment.

Safety Precautions
LASER RADIATION
AVOID EXPOSURE TO BEAM
CLASS 3B LASER PRODUCT
WAVELENGTH 808 nm
OPTICAL POWER 0.5 W
Never look into any of the fiber optic connectors.
The laser emits an infrared beam that is invisible
to the naked eye. Direct or even reflected light
will cause permanent eye damage.
INVISIBLE LASER RADIATION: Do not stare into
beam or view directly with optical instruments.
Avoid eye or skin exposure to direct or scattered
radiation.
Some EMCenter™ Modular RF Platform plug-in cards use a high power laser to
supply energy to a remote (floating) measuring device. The wavelength of these
lasers is approximately 808 nm. These lasers are high-power, infrared lasers and
invisible to the human eye. Please read the documentation and safety
instructions provided in the separate manual for the specific card.

18 Laser Safety www.ets-lindgren.com
Exposure to any laser radiation during normal operation is not likely because the
EMCenter uses only fiber-coupled lasers. However, for the safety of all
employees, please comply with the following rules:
 When the EMCenter is not in use, power off the unit.
 The remote interlock connection should be connected to an emergency
master disconnect and in series with the room door or fixture
interlocks.
 Connect all fiber cables and install protective covers before switching
on the system. Protective covers are identified by the following label:
 Do not attempt to turn on the EMCenter if the fiber optic cables show
any sign of damage.
Safety Features
To make the EMCenter as safe as possible, the primary safety system of each
plug-in card is designed to work standalone, without any intervention from the
EMCenter. Apart from this, the EMCenter has its own safety interlock system,
which is connected in series with the interlock system of every installed card.
Additionally, the following safety measures are implemented:
 The EMCenter is equipped with a remote interlock system. For
example, this interlock system would prevent inadvertent laser
radiation by preventing someone from entering a shielded room and
stepping on a fiber.
 To prevent accidental activation of the laser, an Acknowledge button
will appear directly after the Laser Start button is pressed. The laser
will start only if this button is pressed within a four-second timeframe.
 A visual Laser On indicator warns the operator of laser activity. The
Laser On LED on the front panel of EMCenter indicates that at least
one laser is active.

www.ets-lindgren.com EMCenter Controls and Connectors 19
5.0 EMCenter Controls and Connectors
Never disconnect the fiber optic cables when
one of the lasers is active.
See Manual Control of the EMCenter on page 25 for information on
using the touchscreen controls.
Front Panel
S TATUS I NDICATORS
There are four status indicators on the front panel of the EMCenter™ Modular
RF Platform:
 Interlock—Illuminates if the external interlock is open, or if one of the
plug-in card interlocks encounters an interlock error.
 Laser On—Illuminates if at least one of the lasers in one of the cards
is active.
 Standby—Illuminates when the EMCenter is in standby mode.
 Power On—Illuminates when the EMCenter is turned on.
