* Helmholtz coil too
DUT
MAGNETIC FIELD AND
VOLTAGE RIPPLE
TEST SETUP
International standards, such as ISO and SAE, require tests with magnetic fi elds
and voltage ripples. The test signal is adapted to the DUT as a frequency sweep.
The application is implemented with the substitution or closed loop method.
autowave.control adjusts the measurement equipment, e.g. an oscilloscope,
for optimum performance and automatically regulates the disturbance signal in
the closed loop method based on the measurement values. It really doesn’t
get any easier!

(Ford CI immunity from continuous power line disturbances test pulse)
Voltage ripple per ISO - or SAE J-
TEST SETUP:
AutoWave (arbitrary generator)
AMP N (amplifier)
Radiating loops (Helmholtz coil)
Current probe
Measuring device (oscilloscope)
TEST DESCRIPTION:
Large magnetic fields such as those found with high currents or in electric mo-
tors can disturb electronic components in the vehicle. The ISO - stan-
dard defines magnetic field tests with the radiated loop antenna or the Helm-
holtz coil. Many vehicle manufacturers (e.g. Ford EMC-CS ./RI )
adapt the international standards using other set-ups and parameters.
No problem for EM TEST equipment!
TEST SETUP:
AutoWave (arbitrary generator)
AMP N/N (amplifier)
VDS N series (DC DUT supply and interference signal)
Voltage probe
Measuring device (oscilloscope)
TEST DESCRIPTION:
Per Ford CI , sine ripples have to be directly superimposed from the DC
source onto the supply line. The closed loop method must be applied for the
test. The entire measurement and regulation is handled by the autowave.con-
trol software.
You can concentrate fully on the DUT, as you should!
SOLUTION:
As the Ford CI standard prescribes it,
the overlapped signal is measured at each
test point in the closed loop process. The
autowave.control software calculates and
automatically increases the disturbance
voltage until the required value has been
reached.
SOLUTION:
The vector diagram shows each
individual test point, including
the configured tolerance of the
test signal.
TEST SETUP:
AutoWave
(arbitrary generator)
AMP N/N (amplifier)
CN N (transformer)
VDS N series
(DC DUT power supply)
Capacitor (HF short-circuit)
Current probe
Voltage probe
Measuring device
(oscilloscope)
TEST DESCRIPTION:
Low frequency disturbance signals in the frequency up to kHz, overlap
onto supply and signal lines and affect electronic systems in the vehicle. The
disturbance signal generated by the amplifier is transmitted over the audio
transformer onto the lines. Many manufacturers vary these tests in terms of
voltage and frequency. In CI , Ford uses a special transformer coupling with
load, which is already integrated in the CN N.

SOLUTION:
Each test device can be selected in
the configuration. The parameters
are saved in the program and are
accessed directly. The cursor position
indicates the voltage of the standard
unit (Vpp) and the frequency in a
graph.
