1.0 Introduction
The ETS-Lindgren EMGen™ RF Signal Generator Plug-in
Card is a modular signal generator with AM, FM, and pulse
modulation, covering a frequency range of 4 kHz to 6 GHz.
EMGen is designed for EMC testing, and quickly and accurately
performs EMC tests without the need for an external modulation
source. Using an internal modulator, EMGen provides CW, AM,
FM, and pulse modulated signals.
The primary test signal of an Electric Magnetic Compatibility (EMC) immunity test
system is generated by an RF signal generator. It produces a modulated or un-
modulated RF signal at a certain frequency and signal level. The EMGen generators
are designed for EMC test purposes in order to perform fast and accurate EMC tests
without the need for external modulation sources.
Components
EMCenter Modular RF Platform (Required)
The EMCenter is a modular EMC/RF test system
that serves as the user and computer interface for
all the plug-in cards and modules. See section
below about processor requirement for the 2-slot
and 7-slot EMCenters using the 7003-002
EMGen module.
EMField Electric Field Generator
The patented EMField is no less than a revolution
in EMC immunity testing. A complete paradigm
shift involves a combination of high-level
integration and a field combining technique,
making several discrete components like
combiner, coupler, power meters, and cabling
superfluous. This product is sold separately.
Software
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

2-Slot and 7-Slot EMCenter Processor Requirement
Note: The 2-slot and 7-slot EMCenter require an ARM processor board with
firmware version 3.3.3 or higher to operate the EMGen 7003-002 interface card.
2-slot and 7-slot EMCenter systems utilizing an X86 processor board and/or
firmware version 3.3.0 or older are not supported and will not communicate with
the EMGen interface card.
To view the 2-slot or 7-slot EMCenter version information, navigate to the main
screen and press the Info button. Slot 8 indicates the processor version of this
EMCenter as shown in the graphic below.
Note: If the EMCenter is not operating the 7000-008 or 7000-009 processor
card, contact ETS-Lindgren to purchase a new 2-slot or 7-slot EMCenter or a
new processor card compatible with EMGen.

Modulation Types
AM modulation —The EMGen supports AM modulation depths of 0 to
100% and modulation frequencies from 1 Hz to 100 kHz, covering the
requirements of all relevant EMC standards.

Introduction
ets-lindgren.com
FM modulation —The EMGen supports FM modulation deviations of 1 Hz
to 100 kHz and modulation frequencies from 1 Hz to 100 kHz.
Pulse modulation: 200 ns - 100 s —The EMGen supports pulse
modulation with ON- and OFF times ranging from 200 ns to 100 s with a
resolution of 100 ns.
Pulse modulation settings —The pulse interval (on/off) of the EMGen can
be set from 200 ns to 100 s This broad range allows for ultimate flexibility in
the configuration of pulse modulation.
Gated Pulse —In addition to standard pulse modulation the EMGen can
also be used to perform Gated Pulse modulation. Gated Pulse testing is
necessary to perform automotive radar pulse testing as prescribed in several
automotive standards (E.G. Ford, General Motors and PSA).
How to use Gated Pulse Modulation
Several automobile manufactures have written standards in which they subscribe the
Automotive Radar Pulse tests. These tests consist of an N-number of pulses in a
certain period of time. When the number of pulses is reached, there must be no more
output for the remaining time during that period.
Explanation of Automotive Pulse Testing
Ford RI-114 Radar Pulse test (EMC-SC-2009) and PSA B21 7110 are using:
Pulse Repetition Rate (PRR) = 300 Hz
Pulse duration (PD) = 3 µs
No. of pulses per second (N) = 50
GM GMW3097-2012 uses:
Pulse Repetition Rate (PRR) = 300 Hz
Pulse duration (PD) = 6 µs
No. of pulses per second (N) = 50
