EMC Immunity and Emissions
EMC - Electromagnetic Compatibility
Three Elements of an EMC Problem
 The ability of a device or system to function
without error in its intended
electromagnetic environment.
 All electronic devices make noise and must
be immune to noise created by other devices
 Measuring the noise from a device is called
“Emissions Testing”
 Simulations of these events called “Immunity
Testing” which means that the devices under
test are immune to the noise

What is EMC?
Special Considerations for Motor Vehicles
 In ISO 7637 and variants, we are
considering transients and voltage drops that
are coupled over battery lines and signal lines
 Immunity Testing simulates ‘Conducted
EMC’ that occurs during normal or error
conditions in a motor vehicle.
 Emissions testing ensures that the noise
created by a device is less than specified
levels.
 Evaluates the performance of components
during simulated real-world EMC events
 These failure conditions are documented
and tests defined by International
organizations (ISO, SAE) and manufacturers
(Ford, VW)
Causes:
 Alternators, Converters, Switching Processes
 Electric Motors, Fuel Pump, Fan Motors
 Lights, Radio
 Every kind of electronic device
 Coupled on Power Lines and Wiring Harnesses
 Engine Start

Simulates Vehicle Wiring Harness
Battery
Source
Oscilloscope
DUT
The application is simple: The DUT is switched off, switched on, or different
operation modes are exercised and any feedback is
measured.
In simplest terms, we’re measuring the DUT’s inductive
kickback.
Emissions Switch – Before or After AN?
Application
Wiring Harness
For applications where the DUT is
far from the switch, the setup
should have the AN between the
switch (simulating the wiring
harness) and the DUT.

Emissions Relay or Electronic Switch?
When to use a relay and when the electronic switch:
Relay
 Voltages over 400V
 Usually must be approved by OEM
 Poor Repeatability, Slow/Chattering
 Must be replaced
 Should be production relay
from the vehicle containing the DUT
Electronic Switch
 Less than 400V
 Fast and Repeatable
 Voltage Drop Must be Accounted For
∆U ≤ 1V at 25 A

Differences Between ISO 7637 and CISPR Artificial Networks
Documenting the DUT Behavior
Items to be Documented:
 Peak Amplitude
 Pulse Duration
 Rise and Fall Times
 Burst Duration (if Repetitive)
 Repetition and Cycle Times
Other Standards
Almost every manufacturer standard adheres to ISO 7637-2 for emissions
measurements. They vary only slightly in setup (switch position and cable lengths).
For this reason, the AES 5501 was designed in several parts so that control over the
position of the switches and cable lengths is easy.
One notable difference is Nissan and Renault with two LISNs:

And other common pulses
Pulse 1 - A simulation of transients due to supply disconnection from inductive loads; it applies to a
DUT if as used in the vehicle, it remains connected directly in parallel with an inductive load
Pulse 2a - Simulates transients due to sudden interruption of currents in a device connected in
parallel with the DUT due to the inductances of the wiring harness
Pulse 2b - Simulates transients from dc motors acting as generators after the ignition is switched
off
Pulse 3a/3b - Occurs as the result of switching processes. The characteristics of this pulse are
influenced by distributed capacitance and inductance of the wiring harness
Pulse 4 - The voltage reduction caused by energizing the starter motor circuits of the internal
combustion engines
Pulse 4 Variants – Most manufacturer variations of pulse four are generally much more
complicated. For example Ford requires up to four arbitrary generators with four outputs to be
perfectly synchronized.
Pulse 5 – Simulation of a load dump transient occurring in the event of a discharged battery being
disconnected while the alternator is generating charging current with other loads remaining on
the alternator circuit at this moment
Magnetic Field Immunity – Simulates magnetic fields generated by electric motors, daytime running
lamps, etc. for DUTs with magnetically sensitive devices.
Transformer Coupled Sine Waves – Sinusoidal noise burst coupled on battery lines

Different automotive standards require different transient pulses. The requirements
are different in:
 Amplitude
 Impulse
 Frequency
 Pulse energy
 Test method, test setup
Where do these differences come from?
 Wiring harness
 Components
 Generator
 etc.
The experience of the standard writer, theoretical evaluations, empirical
measurement values and different test conditions do have a strong
impact on the parameterization of the pulses!

Traditional Pulses Migrated to ISO 16750
In Summary:
Several pulses that were traditionally part of the EMC (ISO 7637) are
being moved to the ‘power quality’ standard (ISO 16750).
These include:
 ISO 7637-2:2004 Pulse 4 -> ISO 16750-2 “Starting Profile”
 ISO 7637-2:2004 Pulse 5a and 5b -> ISO 16750-2
“Load Dump A and B”
This is logical because these are not traditional EMC events, but
instead an issue of power quality. Curiously, Pulse 2b will likely
remain in ISO 7637 even though it could also be classified as a power
quality problem in the opinion of many experts.
Other Variations
Immunity Variations - Overview
Dozens of manufacturer standards exist, and they differ from the
international standards:
 Not all OEM standards are the same, even for pulse 1, 2, 3, 5 - type
transients
 Dozens of variations in starting pulses
 Several new methods of generating even common pulses
 Flexible equipment is preferred for forwards/backwards requirements
 Other Common Tests
Dips and drops (two variations)
Coupling on signal lines (two variations)
“Pulse 7” in a new form
Power magnetics, transformer coupled sine waves
Variations Examples
 Ford EMC CS 2009
Completely rewritten sections including inductive transient fixture
Frequency of many tests increased to 100 kHz
Overview of all new and changed tests available from Teseq
 Ford ES-XW7T-1A278-AC (2003)
Contains Special 4Ω ISO – type pulses
No verification other than defined in ISO 7637-2
 Ford ES-XW7T-1A278-AB (1999)
Contains 4 Ω ISO – type pulses
Contains special Ford verification procedure
Latest version always available at www.fordemc.com
Variations – Load Dump Examples
Actual test parameters vary greatly. Therefore, the test
generator must be able to fulfill all of these ranges listed in the
standard.
Exact test parameters are based on the expected
vehicle/alternator combination, and must be selected at the
advice of a responsible engineer or liaison to the
customer/manufacturer.
Variations – Load Dump Examples
 Numerous manufacturers’ standards disregard the ISO wording for transient
pulses, especially Load Dump
Tests Other than ISO - Coupling on IO & Signal Lines

Capabilities Overview
NSG 5500 – Capacitive Discharge Pulse Immunity Generator
 Teseq has always been at the forefront of the automotive immunity test systems. The NSG 5000 was
the first with systems based on a modular structure the NSG 5500 replaces it to now include an
exclusive 100A standard compact coupler.

and expands on the unique pulse shaping qualities offering the only solution fully compatible with every
immunity requirement from ISO 7637-2: 2004
NSG 5600 – Battery Voltage Variation and Noise Simulation Generator
 Teseq was first with automotive synchronized function generators with the NSG 5200. The NSG 5600
expands on the exclusive single-click programming interface and powerful event cloning features.
 Based on a function generator/amplifier combination, the NSG 5600 includes features for simulation
of vehicle voltage starting profiles, dips and drops, transformer coupled and other sine wave noise and
magnetic field immunity testing

above is generally for advanced pre-compliant simulation only.
Immunity to (low frequency) Magnetic Fields
(Power Magnetics)
 For higher fields an external source can be connected, Autostar automatically switches between the
PA 5640 and the external source.
 Current control mode: The output current, and therefore the magnetic field, is automatically
regulated by Autostar!
 Multipoint calibration: Test points are calibrated prior to testing using a field measurement devise
(loop sensor or current measurement).
 Easy to use and fully automated test environment for magnetic field immunity tests!
Key Questions To Ask Yourself
Key Questions:
 What standards do I need to fulfil?
 Do I have copies of these standards?
 Does it make sense to become an active member in the committee if the standard is a
national or international standard?
 In these standards, what are the parameters of each test?
Pay special attention to battery levels, tolerances, impedance, peak voltage, rise times
and pulse widths.
 Do these tests have a verification procedure?
Can my current equipment fulfil these (check it)?
