1 System Overview
1 System Overview
Not all accessories are used for all tests. The chapter “Perform a test” provides more informa-
tion.
1.1 DOW3000
The DOW3000 generator is a compact system with all wave-
forms for IEC 61000-4-18, IEC 61000-4-10 and several prod-
uct standards. The Generator with an integrated 3-phase
coupling and decoupling network is available in different ver-
sions with a combination of the following circuits.
•Slow Damped Oscillation 100 kHz and 1 MHz
•Fast Damped Oscillation 3 MHz, 10 MHz and 30 MHz
•Insulation Test Impulse 1.2/50 us with 0.5 J
The 7 inch graphic colour touch panel provides an intuitive
and comfortable user interface. Interactive parameter input,
help text and graphic illustrations, guide the user through
the instrument programming process.
1.2 CDN-DOW-DATA-LF (PN 108260)
The CDN-DOW-DATA-LF is a compact coupling-decoupling
network specifically designed to couple Slow DOW signals
on up to eight datalines. Both 1 MHz and 100 kHz signals
can be coupled via 0.5 uF capacitors, either in differential
mode or in common mode according to IEC 60255-26 and
IEC 61000-4-18. Additionally, common mode coupling of
the signal lines directly to PE is possible. The CDN-DOW-
DATA-LF is capable of handling high-power EUTs with AC
or DC voltage. Each line has a decoupling impedance to
protect the auxiliary equipment from the DOW test signals.

EMC
1 System Overview
1.3 CDN-DOW-DATA-HF (PN 108321)
The CDN-DOW-DATA-HF is a compact coupling-decoupling
network specifically designed to couple Slow DOW signals on
2-pair or 4-pair symmetrical high-speed communication lines.
Both 1 MHz and 100 kHz signals can be coupled in common
mode via 0.5 uF capacitors, according to IEC 60255-26. The
coupling is one pair versus another pair or versus multiple
other pairs. Each pair has a decoupling impedance as well
as protection devices to protect sensitive auxiliary equipment
from the DOW test signals.
1.4 CDN-DOW-DATA-HF18 (PN 108495)
The CDN-DOW-DATA-HF18 is a compact coupling-
decoupling network specifically designed to couple Slow
DOW signals on 2-pair or 4-pair symmetrical high-speed
communication lines. Both 1 MHz and 100 kHz signals can
be coupled in common mode via 0.5 uF capacitors, according
to IEC 61000-4-18. The coupling is all lines versus PE. Each
pair has a decoupling impedance as well as protection devices
to protect sensitive auxiliary equipment from the DOW test
signals.
1.5 ADAPTER BOX RJ45-8L (PN 108322)
The ADAPTER BOX RJ45-8L is an Ethernet adapter com-
patible with the CDN-DOW-DATA-HF and CDN-DOW-
DATA-HF18, which allows you to connect your Ethernet
devices directly to the CDNs without the need for special
cabling.

Test coil for Slow DOW magnetic field test according
IEC 61000-4-10. The MF1000-2 has more than twice the
height of MF1000-1 for larger EUTs.
1.7 CN-EFT1000 (PN 103468)
The clamp provides the ability of coupling the damped os-
cillatory waves to the circuit under test without any galvanic
connection to the terminals of the EUT’s ports, shielding of
the cables or any other part of the EUT.
1.8 VERI-CP-EFT (PN 104668)
Transducer plate for CN-EFT1000 capacitive coupling clamp
calibration. The plate has a SHV-BNC connector and a
15 cm strap to bond to the reference ground.

2 Initial Operation
2 Initial Operation
2.1 Unpacking and Checking
1. Check the packaging for signs of damage. If damage is visible, report this to the shipping company
immediately.
2. Gently remove the equipment from the packaging.
3. Check the delivery for completeness using the delivery note and the accessory lists for the var-
ious items. If something is missing, contact EMC PARTNER or your local sales representative
immediately.
4. Check the equipment for any damage. If there is damage, immediately contact the shipping
company who made the delivery.
Retain the original packing material for a safe transport at a later date.
2.2 Installation
The equipment is designed for use under laboratory conditions. Make sure that all fan openings are
unobstructed, that the airflow perforations are unimpeded, and that the minimum distance from the wall
is 10cm. An insufficient airflow can cause the equipment to overheat, which may disturb the operation
and even cause damage.
Most equipment from EMC PARTNER can be mounted in a 19" Rack. A special rack mounting
kit is available. Contact your local sales representative for a quotation.
2.3 Powering the Equipment
Check that the local AC-supply is suitable for the equipment. Power rating of the instrument is indicated
on the type plate next to the AC power supply connector located on the rear panel. Only use the supplied
power cord to connect to your public power supply.
The equipment must always be connected to protective earth. Check the earth connection on
your power outlet before you connect and turn on the equipment.
2.4 Safety Circuit
The generator is equipped with a safety circuit. As long as the safety circuit is open, no test can be
started. To close the safety circuit
1. connect the auxiliary connector on the rear panel
2. pull out the emergency stop button on the front panel with a slight turn clockwise
A closed safety circuit is indicated by a red illuminated emergency stop button
