NSG 5500
Automotive transient immunity tests
NSG 5500 system. This compact mainframe houses
the common system components and accommodates
the standard pulse generators. All testing is available
from one output connector. An electronic switch to
corporated in the NSG 5500. Additional inputs and
outputs are located on the rear panel for test
execution control purposes and the monitoring of
error signals, oscilloscope triggers, gate start/stop
commands, etc. Overall control is via a PC running
AutoStar
TM
under Windows.
NSG 5500 modules. The NSG 5500 offers unpreced-
ented flexibility for transient testing. Schaffner has
designed a solution with various transients in one
modular and upgradeable chassis. The basic ISO
7637 tests for pulse 1, 2a, 3, 5, 6 and 7 and variants
are integrated into the same chassis. Optional pulse
4 and pulse 2b control is available, however, use
with the NSG 5600 offers several benefits over this
budget solution. Additionally, when standards
change, as they do every year, the NSG 5500 system
may be upgraded with different modules so that
your new and old modules may both be retained,
either exchanged with new Gemini modules or
loaded into an optional expansion chassis. Based on
our exclusive Gemini technology, Schaffner offers
the most flexible and upgradeable system in the
world to protect the users’ investment in test equip-
ment.
All NSG 5500 generators are calibrated in accord-
ance with ISO 7637-2:2004 or manufacturer-specific
standards. Schaffner continues to maintain back-
wards compatibility and yet push the state of the art
for EMC immunity testing.
The compact and modular NSG 5500 solution offers the generators necessary for
tests with capacitive discharge pulsed interference as called for by ISO, SAE, DIN
and JASO, and others. The established test specifications for passenger cars
together with the new standards for commercial vehicles published by these
international and other bodies are fully covered, as are the most company-specific
standards from vehicle manufacturers.

Based on our exclusive Gemini technology, Schaffner offers the most flexible and
upgradeable system to protect the users’ investment.
Switching actions with inductive and other loads
influenced by complex inductances of the wiring
harness all create disturbances that must be
simulated. ISO and SAE have defined these tests
as pulse 1, 2 and 6. The MT 5510 produces these
test pulses in conformance with the relevant
standard. In order to be able to cope with a com-
pany’s own test methods, the generator module also
provides a much greater range of selectable para-
meters, considerably higher test voltages, additional
impedances and pulse widths.

Transient generator ISO pulse 1, 2, 6 and variants
Alternators produce a high-energy (load dump)
pulse on a vehicle’s power harness when the battery
is disconnected. The LD 5505 simulates the corre-
sponding pulse 5 specified by numerous standards,
and the clamped load dump pulse 5b. Some vehicle
manufacturers have expanded upon these specifica-
tions - in most cases by making them more stringent.
The generator takes this into account.
Contrary to the classic concept, the unit is built
around an active pulse shaping circuit. While still
compliant with ISO 7637-2 Annex E, this is the best
and most cost-effective method to reach the full
range of pulse requirements. For example, ISO 7637-2
requires 40 - 400ms, which the LD 5505 meets easily.
Other manufacturer may utilize older technology, take
shortcuts and do not allow the full range as required
by the standards. Schaffner’s advanced technology
also enables much greater variability of the pulse
parameters to be achieved and facilitates better re-
producibility. The RM 5505 impedance box is avail-
able, which sets up the generator impedance using a
bank of power resistors.

LD 5505
Load dump generator
The only load dump generator capable of the full range of pulses required by
most standards.
The FT 5530 simulates fast transient interference
injected onto a vehicle’s electrical network through
switching processes influenced by the wiring
harness that can affect the correct operation of
electronic units. The FT 5530 simulates EFT bursts
with pulse widths of 100 or 150ns in conformance
with the standards for pulse 3a/3b interference
phenomena. The EFT generator more than meets
the automotive industry’s increasing demands with
its technical properties exceeding the specifica-
tions laid down in the standards by several factors:
higher pulse voltages, burst frequencies and pulse
variations and other burst specifications including
functions for weak spot analyses during long-term
trials.

CDN 500
Capacitive coupling clamp
The coupling clamp CDN 500 is manufactured exactly
in accordance with the drawings and specifications
of ISO 7637-3 for capacitively coupling the transients
onto cables and wiring harnesses. With its charac-
teristic impedance of 50Ω, the CDN 500 coupling
clamp is connected to the generator via a coaxial cable
and terminated on the far side with a 50Ω load re-
sistor. A suitable terminating load is available as an
accessory under the type number INA 5030, which
also provides a measurement output via a 40dB
attenuator. The coupling clamp will accept ribbon
cables as well as round cables of up to 40mm diam-
eter. The effective coupling capacitance depends on
the cross section and the material of the cable used;
a typical value being around 100pF.
