3.2. Burst generation
Discharge switch:
The discharge switch is a highly reproducible semiconductor switch. Spike frequencies up to 1000kHz are by a
factor of 200 higher than recommended in the actual EFT standards. This means of course that also the pulse
energy would be 200 times higher. This is not generally possible for the high voltage switch. Therefore the
following limitation protects the pulse forming circuit against overload:

3.3. Coupling decoupling network
The decoupling part of the coupling network has to:
- filter the interference pulses in the direction to the power supply;
- protect other systems that are connected to the same power supply and
- realize a high impedance of the power supply, e.g. battery supply.
3.3.1. Coupling/decoupling network for ac/dc power lines
The coupling network has to couple the interference pulses to the lines of a power supply system (AC or DC). As
coupling devices capacitors of sufficient strength and bandwidth shall be used according to IEC 61000-4-4.

The coupling on signal lines can usually not be effected capacitively without interfering with the signal flow. It is
often impossible to contact the required circuit (direct), e. g. coaxial or shielded cables. In this case the coupling
is realized with the capacitive coupling clamp. The interference simulator can be connected on both sides of the
coupling clamp.
3.3.2. Capacitive coupling clamp
- The coupling clamp is not matched by 50 ohm. If the clamp is matched there exists an additional magnetic
coupling, which may cause completely different test results.
- The clamp should be placed in a distance of 0.5m to the equipment under test. When using shorter distances,
the EUT may be influenced by radiation.
- If the EUT is built up by two different equipment, the test should be conducted on each single equipment with
the required distance.

3.4. Burst Test Setup
- The test generator and the coupling network should be connected to the reference ground plane (acc. to high
frequency requirements).
- The equipment under test must be isolated from the reference ground plane. The distance should be 10cm.
Being part of the EUT, these requirements are also recommended for all connected cables. The EUT should
only be grounded if this is recommended by the installation guideline. For safety reasons, the test without any
ground connection should be conducted as well (at 100MHz 1m ground cable has an impedance of about 600
ohm)
- Whenever possible the test set-up and the cabling should always be the same; e.g. for testing power lines it
would be possible to fix the cables on the test table for all tests in the same way.
- Lines under test and all other lines should be decoupled strictly.

3.5. Computer setup for EFT/Burst testing.
During immunity tests high frequency interference is generated. Due to the length of the connected lines, a
certain part of this energy will be transformed into radiated interference.
Therefore the operator shall be aware that systems and installations in the neighborhood, even those not being
part of the test set-up can be disturbed.
Especially for fully automated test systems, where simple computers may be used, EMC problems within the test
system may occur. To avoid such disturbances in the following paragraphs some information is given to which
the operator has to taken care:
- EM TEST generators are tested with the maximum test level. If no damage has been occurred the equipment
must be seen as immune.
- The interference always will enter into a system at the weakest part. Within a computer controlled system the
weakest unit is almost the computer with its interconnection lines and the peripheral equipment.
- The most critical test concerning the above mentioned problems is the burst test according to IEC 1000-4-4.
This is a high frequency test, which may radiate extreme interference fields to the environment.
Concerning the test set-up the following points be explained:
1. The burst generator must be connected very good to the ground reference plane on the table.
2. The ground reference plane shall be connected to the protective earth system. For tests within a shielded
room the connection shall be made to the walls of the room.
3. The test set-up shall have one single ground reference point (not several)
GROUND LOOPS SHALL BE STRICTLY AVOIDED
4. The central ground reference point shall be located where the EFT generator is connected to the ground
reference plane. At the same point the reference ground plane shall be connected to the protective earth
system or to the shielded room.

EM TEST EFT 500 Series
Manual for Operation V 2.00 15 / 21
For conducting the test the following points shall be taken under consideration:
1. It is not allowed to touch the EUT or the cables under test during a running test. The test results will be
influenced and are no more reproducible.
2. If the operator in contrary touches directly the EUT or the connected lines increased radiation from the test
set-up is generated. The operator itself will radiate and/or will cause ground currents into the whole
environment.
3. As larger the dimensions of an EUT are, as higher the radiation of high frequency energy will be.
4. Especially the capacitive coupling clamp with its length of 1m radiates.
5. Auxiliary equipment as well as computer can be influenced directly due to the radiation.
Remarks:
Even the use of fiber-optic links for the communication between a computer and EFT does not help in case of
direct radiation. The computer and its lines will be directly influenced and the data transmission will be disturbed.
6. The influence of direct radiation can be reduced by increasing the distance between a computer and the test
set-up. In any case a minimum distance of 3m shall be available.
It is not only the length of the cable but also the physical distance between computer and test set-up which is
important to take care to.
7. It is shall be strictly avoided to put the computer directly onto the ground reference plane of the test set-up.
The computer then is part of the test set-up and will also be tested. Mostly all computers are not immune to
this test and will be disturbed.
What to say about the computer:
1. Do not use oldest equipment available in your company. Actual computer show better behavior to what EMC
concerns.
2. Do not use notebooks for this application. Laptops are fully manufactured within a plastic housing and therefore
are very sensitive to all kind of interference.
4. It would be better to use tower- or mini-tower equipment. They are at least partially screened. The interface
connectors are mounted on metallic surfaces so that the screen of the communication lines can be connected
to the chassis.
5. The screens of the RS 232 and IEEE cables must be connected to the chassis of the instruments at both
sides, at the computer and at the EFT generator.
6. The communication cables, RS 232 and IEEE, shall be screened. Do not use standard cables, consumer products
with plastic connectors.
These cable types are using mostly very bad designed cable screens. The contact to the housing of the
connector is mostly realized with a small cable, which is very bad under the aspect of rf screening.
Please take care that the screen is connected very good to the metallic housing of the connector and that the
connector is screwed to the housing of the generator.
This mostly is the problem when using the RS 232 interface. Especially those cables are badly designed. For IEEE
cables very good products are available (e.g. HP).
7. The weakest parts within the computer system are the peripherals, as keyboard and mouse. Both products
are not designed to operate under these severe conditions.
It is very easy to make the design better. The operator would be able to do it for himself.
What is the problem ?
The screen of the cables between a computer and the keyboard (mouse) are soldered directly to the printed
circuit board.
The screen shall not be soldered to the print, but to another „ground reference plane“.
e.g. put into the keyboard, directly under the keyboard print a broad copper foil area. Connect the screen of the
cable to this copper foil, without any connection to the print. You will see a dramatic change to better results.

5. Maintenance
5.1. General
The generator is absolutely maintenance-free by using a solid state semiconductor switch to generate transients.
5.2. Test set-up
When setting up the test national and international regulations
regarding human safety have to be guaranteed.
It is recommended to connect the simulator to the ground reference
plane of the test set-up.
The generators of the series 500, UCS, VCS, CSS, TSS and CNI, can
be linked together to a fully automotive test set-up.
The set-up communicates via the IEEE / GPIB bus and is controlled by
ISMIEC software. For setting up the system see the following figures:
Each generator can be operated individual as a single equipment.
5.3. Calibration and verification
The EM Test equipment are calibrated in the factory and marked with a
calibration-tag. The measuring instrument is traceable to the Swiss Federal
Office of Metrology.
The calibration date is marked. The validity of the calibration is in the area of
responsibility of the users quality system.
Example: EM Test calibration-tag
Please refer to the corresponding standard before proceed a calibration or verification. The standard describes
the procedure, the tolerances and the necessary auxiliary means. There are suitable calibrations adapters to use.
All calibrations and verifications are always without mains supply voltage on the impulse- or coupling network
output.
Danger
Before starting the calibration or verification
remove the EUT Mains Supply
from the generator and from the coupling network
