decoupled by the internal coupling/ decoupling network.
2 Reference ground connection
The generator has to be connected to the reference ground plane of the test set up.
3 Pulse input for one external generator
The UCS 200N includes a central coupling matrix. The pulse output of an external Load Dump LD200 or
MPG 200 S20 generator can be connected to this input. The Load Dump pulses then will be available at the
central DUT output at the front panel of the UCS 200N

14 Fail detection FAIL 1 (TEST STOP)
The BNC input FAIL 1 can be used for DUT monitoring. In case of a low going signal (to chassis ground) the
UCS 200N will stop pulse generation and the actual running test routine is paused. The test routine than can be
stopped completely or can be continued from break point. A message of FAIL 1 is indicated in the LCD display.
15 Fail detection FAIL 2 (TEST PAUSE)
The BNC input FAIL 2 can be used for DUT monitoring In case of a low going signal (to chassis ground) the
UCS 200N will stop pulse generation and the actual running test routine is paused as long as the low level
signal is available at the FAIL 2 input. The test routine continues automatically as soon as the low level signal
goes to high level. A message of FAIL 2 is indicated in the LCD display as well as in the iso.control software.

The simulator is operated by an easy menu control system. Seven
function keys are available to select parameters and functions. All
functions are indicated on the display; max. 8 lines and 40 characters.
The selected parameter is blinking and can be changed by turning the knob (incr./decr.).
➔ : The digit to be changed can be selected with the cursor (➔).
- Setted values are direct indicated on the screen.
- Status on the bottom lines shows the desired status after pressing the function key.

F1 Pulse 1
Pushing the function key F1 opens the test menu which supports the so called test pulse 1. The basic pulse for
this is defined in ISO 7637-2:2004. The menu F1 supports various different and modified type pulse 1 tests. In
Quickstart mode all parameters can be adjusted during the running test.
F2 Pulse 2
Pushing the function key F2 opens the test menu which supports the so called test pulse 2. The basic pulse for
this is defined in ISO 7637-2:2004. The menu F2 supports various different and modified type pulse 2 tests. All
parameters can be adjusted during the running test.
F3 Pulse 3a / 3b
Pushing the function key F3 opens the test menu which supports the so called test pulse 3a and 3b. The basic
pulse for this is defined in ISO 7637-2.3. The menu F3 supports different preprogrammed test level for pulse 3a
and 3b tests. All parameters can be adjusted during the running test.
The UCS 200N Sx have no pulses 3a/3b.
F4 Freestyle
The Freestyle menu makes it possible to program the rise time and the pulse duration of the generated transients
over a broad range. This enables to easy adapt the generators output pulses to new requirements.
It also allows the user to program his own specific test pulses, e.g. to test beyond the existing requirements.
This mode is used for pulses in the s and ms range for rise time and pulse duration. It can not be used for
programming parameters in the ns range.
The special models of UCS 200N Sx have no freestyle function.
Remark : The pulses in Freestyle are not defined standard pulses
F5 External
The operator can connect external devices ( like Load Dump, MPG 200 S20...) at the rear of the UCS 200N. The
pulses are then available at the central output of the UCS 200N. By selecting F5: External the operator enables
the internal coupling matrix to be used via the front panel of the external generator.
Coupling to 50output the LED does not light on.
F6 Standards
In this menu the UCS 200N supports the following standard pulses:

Press CHANGE and the test parameters parameter can be changed.
Select the desired parameter with the related function key and change the value by turning the front panel knob.
The cursor allows the user to define the digit to be changed (fast or slow change).
Press START and the test starts immediately with the displayed test parameters.
The operator now can navigate with the Cursor from parameter to parameter. The blinking parameter can be
changed by turning the front panel knob.
Press ESC will bring the user back to the previous menu level.
All function keys except F2 (manual trigger) can Stop the test routine.

User Test Routines
The user can program, save and recall his own specific test routines. The next pages shows the selection of the
functions. After selection the last used test parameters will be indicated on the display.
Customized test routines
The software controls user test routines according to the specification of the user. All limitations are the same as
defined under Quick Start.
Voltage change after T by VThe test voltage is increased
from V1 to V2 by steps of V after the defined test time T. All
limitations are the same as defined under Quick Start. The
limitation of the max. generated number of spikes is related
to the higher voltage of V1 or V2.
Frequency change after T by f
The spike frequency is changed from f1 to f2 by steps of f
after a defined test time. All limitations are the same as
defined under Quick Start. The limitation of the max.
generated number of spikes is related to the higher voltage
of V1 or V2.

Note: The maximum values for frequency, burst duration td and voltage are in dependence of each other and therefore limited by the
generator performance. The practical limits of the UCS200M are 20kHz for f2 and 50ms for the burst duration td. The limits of the
generator model UCS 200N4 are approx. 10 times higher.
Random burst release
No repetition rate is selected. The single burst will be
triggered by statistics in the limits of 20 to 2000ms as time
between two Bursts. All limitations are the same as defined
under Quick Start.

Discharge switch:
The discharge switch is a highly reproducible semiconductor switch. Spike frequencies up to 200kHz are by a
factor of 20 higher than recommended in the actual standards. This means of course that also the pulse energy
would be 20 times higher.

Test Set-up
IMPORTANT
•The test generator and the coupling network should be connected directly to the reference ground plane.
•For the pulses 3a/3b the connection generator –groundplane shall not be longer than 100mm. The
connection shall be suitable for high frequencies.
•The DUT shall be isolated from the reference ground plane by 0.1m. This is also recommended for all
connected lines. The DUT should only be grounded if it is also recommended for the real installation in a
vehicle.
•Whenever possible the test set-up and the cabling should always be the same.
•The diodes or zeners are optional only for pulse 5b (suppressed)
•The load resistor Rv is optional. This resistor is used to match the generator to the low impedance battery
supply system. So far, as known, this is only used within the Ford ES-XW7T specification where Rv = 0.7
During the test the measuring circuit shall be removed from the test setup
4.6.2.
Coupling decoupling network
The decoupling part of the coupling network has to:
- to decouple the pulses from the battery or 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.

Tests with the capacitive coupling clamp ACC
•The coupling on signal lines is realized with the capacitive coupling clamp.
•The coupling clamp has to be terminated with a 50 ohm resistor.
•The clamp should be placed in a distance of 0.5m to the equipment under test. When using shorter
distances, the DUT may be influenced by radiation.
•If the DUT is built up by two different units, the test should be conducted on each single unit with the required
distance.
