For Frequency >50kHz to 100kHz the VDS output voltage must be limited to max. 3Vpp.
Therefore the analogue input signal must be limited to max. 0.7Vpp !

Rear view

1 Test supply output

At this output the generator can be loaded with the maximum current of 15A // 30A // 35A // 50A // 100A

depending on the type of generator. This output is also used for the internal wiring in a complete rack system
installation.

2 Reference earth connection

During immunity tests it may be useful to connect the simulator with reference earth plane of the test set-up.

For complete rack installations all different test generators shall be grounded at this point.

3 Analogue input 0-10V

The internal amplifier can be controlled by an external signal generator. The operator therefore shall select

the User Test Routines of the VDS part and start the menu Extern. The amplifier than is ready to be remote
controlled.

The input signal range is 0-10V in the frequency range of 0-50kHz. The output power (EUT test supply) than

would result in 0-30V or 0-60V and a nominal current depending on the type of instrument. The frequency
range is 50kHz for up to 6Vpp and 25kHz for up to 16Vpp.

2.6.

The consequence of the structure is that between the different test modes

the DUT supply is automatically switched off.

Safety with voltage setting

To ensure a safe operation of the DUT (Device Under Test) some restrictions in the operation of the instrument
are built in. These restrictions are explained within this paragraph.

The VDS basically is divided into 2 different operation modes, which includes their individual test routines and
supply voltage setting. The four different modes can be listed as follows:

DC Source (VDS Generator - User Test Routines - DC Source)
Within this mode the VDS is used as a simple DC power source in the range of 0-60V // 0-15A // 30A // 50A //
100A // 200A and an integrated current limiter.

Arbitrary Wave Simulator

Within this mode the VDS generates arbitrary waveforms and signals which are specified in different standards,
such as pulse 4 of ISO 7637.

All these different test modes are changing generally the voltage supply setting of the generator in a different
way. This would mean a certain risk for the operator to burn out the connected DUT by higher dc supply voltages
as intended. Therefore it is decided to clearly separate the two test modes by the following structure listed :

1. DC source

When entering the Arbitrary Wave test mode the dc output voltage of the VDS 200 is automatically set to the
nominal voltage of the DUT. The actual nominal voltage can be defined in the service menu under "Set-up".
When starting the related test routines the output voltage will be generated as per the setting shown up in the
display for each individual test routine.

- The operator can accept this setting and start the test immediately .

- The operator can first change the parameters and than start the test.
When leaving the test mode DC source the output voltage is automatically reset to the nominal supply voltage of

the DUT. The previous voltage setting will be stored in the test file.

2. Arbitrary Wave Simulator

When selecting the Arbitrary Wave mode the output voltage will be set automatically to the nominal voltage of the
DUT. The actual nominal voltage can be defined in the service menu under "Set-up".
When starting the related test routines the output voltage will be generated as per the setting shown up in the
display for each individual test routine.

- The operator can accept this setting and start the test immediately.

- The operator can first change the parameters and then start the test.

Test Equipment

Construction

The Voltage Drop Simulator VDS 200 is built in a 19" housing and is divided into two parts, the control unit and the
power electronics. The 100A type is designed in a small rack on wheels.

Control unit

The control unit is based on a microprocessor system and a driver board which includes a galvanic decoupling
between the control unit and the power electronics. The firmware for controlling the system is stored in two
EPROM’s. The control unit is built up by 3 boards, the power supply, the micro-controller board and the interface
board.

Power supply unit

The power supply unit supplies voltages of +/- 15V, + 5V, + 24V for all other modules of the simulator. The unit is
fused on the back of the device in the power supply socket.

Micro-controller unit

This unit controls the entire functions of the power supply simulator and simultaneously organizes the data
transfer via the serial RS 232 or parallel IEEE interface.
The desired test parameters are preselected via the function keys or the knob (incr./decr).

I / O Controller

All control parameters entered via the keyboard or the interfaces are interpreted by the I/O controller. In addition

Arbitrary Wave Simulator

The following diagram shows the principal layout of the amplifier. By controlling the semiconductor switches
nearly any waveshape can be simulated.

The amplifier is used generally as a high power dc supply for feeding the equipment under test.
Additionally with the built in waveform generator arbitrary waveforms which are required in many standards can

be generated, such as pulse 4 and pulse 2b of ISO, sine wave sweeps and so on.
The unit can also be used as a high power amplifier up to 50kHz bandwidth, see the limitations. For this purpose

the unit can be controlled by an external signal generator at the BNC input (0-10V). This input is located at the
rear panel of the instrument.

Overvoltage protection

General

With the overvoltage protection the user can protect the output voltage in case of an unwanted overvoltage at the
VDS200 output in case of wrong voltage setting or failure. The overvoltage protection is a hardware crow bar that
will cut down the voltage output of the VDS 200 and shut down the output voltage.
The overvoltage protection is available at the following devices:

Function

The overvoltage protection consists of two parts:
Crowbar switch with the hardware.

A TVS diode will limit the max. overvoltage in the first µs till the security power switch will disconnect the DUT
from the dc source. A crowbar switch will discharge the energy storage capacitor bank via a 1.2Ω resistor to zero.

Controller
An analogue controller controls the overvoltage protection independent.

Blockdiagram

Protection levels

The overvoltage protection is manually selectable to the following protection levels

The factory setting is 60V if the user did not order another protection level.

DANGER

The protection level setting must be done from people who are trained to work with electrical
devices.

DO not touch the heat sink or electrical parts inside the VDS200. These elements can be
under voltage during operation and even when the device is switched off (up to 95Vdc).

Warning

After switch OFF the VDS200N do not touch any electric conducted parts as long the two
LED on the printed circuit board are illuminated ( some few seconds).

Test fail release button pressed will trip

the overvoltage protection immediately.

Attenuation curve according the correction table

Using an individual amplitude control with sine ripple, the user must compensate the attenuation of the amplifier
frequency bandwidth. The table below shows the attenuator factor for frequencies range 1kHz to 100kHz.

The ripple voltage must respect the voltage limitation (see chapter 4.7)

Correction table for sine ripple 1kHz to100kHz

Voltage attenuation at sine ripple frequencies

The amplitude at sine ripple is compensated in manual operation by the VDS 200N firmware.

When setting up the test national and international regulations regarding human
safety have to be guaranteed.

The test setup must be conform to the national and international regulations.
It is recommended to connect the simulator to the ground reference plane of the

test set-up.
The generators of the series 200, UCS, LD, PFS, VDS and AutoWave, can be

linked together to a fully automotive test set-up.
The set-up communicates via the IEEE/GPIB bus and is controlled by ISM ISO

software. For setting up the system see the following figures:
Each generator can be operated individual as a single equipment.

6.3.

ATTENTION

Working with iso.control please connect VDS 200B to the PF1 input of PFS 200B

With this set-up all DIPS and DROP
out tests are performed automatically
with iso.control software.

Maintenance

General

The generator is absolutely maintenance-free by using a solid state semiconductor switch to generate the fast
transients.

Test set-up

Test set-up with software iso.control

By using iso.control software :

 Connect VDS with PF1 input.
 Connect the external dc source ( controlled from PFS 200 ) on input PF2. Connect the analogue output from

PFS 200 to the external dc source.

 As external dc source we propose a VDS 200, RDS 200 or an other dc source with an analogue dc input for

control.

The EM Test equipment are calibrated in the factory and marked with a calibration
mark. The used measuring instruments are traceable to the Swiss Federal Office of
Metrology.
The calibration date is marked. The validity of the calibration is to the responsibility
of the user’s quality system. Neither the certificate of calibration nor the
corresponding label mark any due date for re-calibration.

Calibration and Verification

Factory calibration

Every EM TEST generator is entirely checked and calibrated as per international standard regulations before
delivery. A calibration certificate is issued and delivered along with a list of the equipment used for the calibration
proving the traceability of the measuring equipment. All auxiliary equipment and accessories are checked to our
internal manufacturer guidelines.

The calibration certificate and the certificate of compliance (if available) show the date of calibration.

Guideline to determine the calibration period of EM Test instrumentation

Our International Service Departments and our QA Manager are frequently asked about the calibration interval of
EM TEST equipment.

EM TEST doesn’t know each customer’s Quality Assurance Policy nor do we know how often the equipment is

used and what kind of tests are performed during the life cycle of a test equipment. Only the customer knows all
the details and therefore the customer needs to specify the calibration interval for his test equipment.

In reply to all these questions we like to approach this issue as follows :
EM TEST make use of a solid state semiconductor switch technique to generate high voltage transients. A
precious advantage of this technique is the absolute lack of periodical maintenance effort. In consequence
thereof a useful calibration period has to be defined based on two criteria :

- The first one is the customer’s Quality Assurance Policy. Any existent internal regulation has to be applied at

highest priority. In the absence of such internal regulation the utilization rate of the test equipment has to be
taken into consideration.

- Based on the experience and observation collected over the years EM TEST recommend a calibration

interval of 1 year for frequently used equipment. A 2-years calibration interval is considered sufficient for
rarely used test generators in order to assure proper performance and compliance to the standard
specifications.

Calibration of Accessories made by passive components only:

Passive components do not change their technical specification during storage. Consequently the measured
values and the plots stay valid throughout the storage time. The date of shipment shall be considered as the date
of calibration.

Periodically In-house verification

Please refer to the corresponding standard before carrying out a calibration or verification. The standard
describes the procedure, the tolerances and the necessary auxiliary means. Suitable calibration adapters are
needed. To compare the verification results, EM Test suggests to refer to the waveshape and values of the
original calibration certificate.

All calibrations and verifications are always done without mains supply voltage connected to the coupling network
input.
