ECAT
Model E411
®
EFT/Noise
Burst Simulator for 
IEC 1000-4-4 to 4.4 kV
FEATURES
™
• All test parameters under full software control via
KeyTek BurstWare
Polarity Burst Voltage 0-360° Line Sync 
Frequency Burst Duration Coupling Modes 
Period Test Duration
• Burst Voltages from 200V to 4.4kV
• IEC specified 5ns/50ns impulses into 50 ohms- also
meets the proposed 5/100ns requirement into a high 
impedance.
™
:
A plug-in module for ECAT 
systems for testing in accordance 
with IEC 1000-4-4 (IEC 801-4).
• 50 ohm source impedance
• Built-in pulse monitor, attenuated to 1kV/V 
for convenient monitoring without the need for 
high voltage probes.
• Real World EFT options including Chirp and 
frequencies to 2MHz.
SYSTEM BENEFITS
• The ECAT is configurable as a compact, 
standalone system with one test capability or as 
an integrated, multiple capability tester. 
• Unparalleled safety features for high voltage 
testing, including a complete interlock system that 
not only disables simulator operation if activated, but 
completely removes AC mains power from the EUT, 
when using any KeyTek AC mains coupler/decoupler.
• Automatic report generation using KeyTek’s 
exclusive Windows
• Modular system construction provides the ability to
upgrade test capabilities as requirements change or 
evolve.
• Single port testing for Surge, EFT and PQF
coupled disturbances allows changing test modes 
without switching off power to the EUT. This avoids 
lost time due to re-initializing the EUT between tests.

MINIMUM SYSTEM REQUIREMENTS
E100 series control center and 
E000 blank plug-in module (If no other half-width 
module is ordered)
AVAILABLE OPTIONS
E411-CH Chirp capability – provides an output in
which the amplitude increases and the 
frequency decreases during the burst, 
similar to actual EFT events.
E411-2MHz: Hardware option to provide burst 
frequency operation to 2MHz, 
at voltages to 3kV. 
CCL-4: A covered, safety-interlocked capacitor
clamp for coupling the burst to I/O lines 
(including data and signal lines). All 
clamp surfaces are nickel-plated and 
the hinges are nickel-plated, beryllium 
copper finger-stock to insure excellent 
RF performance over time.
CCL-4/S: A covered, safety-interlocked capacitor
clamp for coupling the EFT/Noise 
burst into I/O lines (including data 
and signal lines).

ECAT: AN EXTRAORDINARY CONCEPT IN EMC 
TESTING FOR VULNERABILITY TO SURGE, 
EFT AND POWER QUALITY.
ECAT is a totally integrated and modularized system
which offers unprecedented testing ease, accuracy and 
versatility to manufacturers, test houses, and anyone 
who will be testing for effects of Pulsed EMI.
ECAT is designed to test products according to a broad 
range of international standards developed by ANSI, 
the IEC, CENELEC and other agencies. The European 
Norms, developed by CENELEC, became mandatory 
on January 1, 1996 for all equipment shipped into the 
European Union or shipped across EU borders.
