The VDS 200Q is four-quadrant linear power amplifier with a
very low source impedance. It simulates the battery power
supply of a vehicle and complex power supply distortions in the
power range up to 12 kW. Many different waveforms are
integrated as standard such as pulse 2b required by ISO 7637
and the starting profile from ISO 16750 as well as requirements
from many manufacturers’ standards like LV 124 and LV 148.

2.3.
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.
CAUTION:
The VDS 200Q series, as well as most linear power amplifiers will create spikes at start and stop.
These are limited to 15V normally, but inductive loads can generate high voltages. Do not touch any
conducted parts of the system and be sure to remove the DUT during power up and shut down or
damage may occur.
Do not use the VDS 200Q with a parallel battery.
A four-quadrant source, like the VDS 200Q can supply both positive and negative voltage as well as positive or
negative current in any combination. It can also sink current that may be supplied from external sources. Often,
using a classic 'source' (power supply or 1 - 2 quadrant source) the user felt the need to buffer the voltage in
order to get inrush or to properly simulate the impedance of the battery in the car. This, of course, can no longer
be controlled as the source simply becomes a charger for the battery.
However, when using a four-quadrant source like the VDS 200Q and the source's voltage is set lower than the
battery, the battery can discharge through the source.
This can result in a dangerous condition, not only for the four-quadrant source, but also because you've
effectively short-circuited the battery when setting the voltage to zero (or switching the four-quadrant source off!).
Remember that all sources must have a source impedance of <10 mOhm according to ISO 7637.
Finally, by shorting (or overcharging) the battery, the battery can actually overheat, crack (releasing acid!) or
even explode due to the release of hydrogen.
CAUTION:
Do not use a parallel battery with the VDS 200Q or a dangerous condition can occur by exceeding
the current of the VDS 200Q, and/or overheating the battery.
The VDS 200Q basically is divided into 2 different operation modes, which includes their individual test routines
and supply voltage setting. The different modes can be listed as follows:
DC Source
Within this mode the VDS 200Q is used as a simple DC power source in the range of up to 80V; and an
integrated current limiter.
Arbitrary Waveform Simulator
Within this mode the VDS 200Q generates arbitrary waveforms and signals which are specified in different
standards, such as pulse 4 of ISO 7637.

AMETEK CTS VDS 200Q Series
Manual for Operation V 1.3.1 10 / 36
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:
Analogue input +10/-10V
The amplifier can be controlled by an external signal generator. The operator therefore shall select the User
Test Routines of the VDS 200Q part and start the menu Extern. The amplifier is then able to be remotely
controlled.
The input signal range is +10 to -10V in the frequency range of 0-250kHz. The output power (EUT test
supply) is capable of 0-40V or 0-80V and a nominal current depending on setting. For example, in the
normal (8x) gain setting, a 2V input signal would result in 16V out. Please note, the 3dB guaranteed
bandwidth of 250 kHz is not guaranteed when controlling the source with the BNC analog input. Typical
bandwidth when using an external control signal is 150 kHz.
1. DC source
When entering the Arbitrary Wave test mode the dc output voltage of the VDS 200Q 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.
When leaving the test mode Arbitrary Wave Simulator, the output voltage is automatically reset to 0V. The
previous voltage test parameters will be stored and can be used for the next test.
The consequence of the structure is that between the different test modes
the DUT supply is automatically switched off.
Be sure to select the appropriate bandwidth (Capacitive, Standard, High Freq.) in the Service
menu appropriate for the necessary test frequency.
While the full voltage and frequency can be programmed, bandwidth is typically measured at
the -3dB point. Therefore, please keep in mind that there will be some attenuation at the
maximum frequencies of each range that may have to be compensated for.

Description of the menus
The simulator VDS 200Q 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 (➔ ).
- Set values are directly indicated on the screen.
- Status on the bottom lines shows the desired status after pressing the function key.
ESC : ESC will take you back to the previous level in the menu and set the displayed
values. The latest settings are stored automatically and will be recalled when the
menu is selected again.
EXIT : The firmware will reset to the main screen.

In this mode, the internal signal generator is used to generate arbitrary waveforms as required in different
standards.
The operator can use the generator in this mode as a,
- DC power supply source,
- powerful power arbitrary wave generator with integrated test routines
- or simply as a battery simulator
The amplifier can be remote controlled by any external arbitrary generator. External generators shall be
connected at the rear part of the equipment. Any waveform can be generated up to the upper bandwidth of the

VDS Externally via the analog input
The power amplifier can be driven by an external control voltage (-10 to 10V), e.g. from an external waveform
generator.
For this purpose the operator must select VDS Extern by pressing the related function key. The Extern
mode is displayed and the unit can only be operated via the coaxial BNC input ANALOG IN at the rear part.
Parameters:
Input voltage at BNC input :-10...10V dc
