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

connect and disconnect the battery supply is in-

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.

Technical specifications LD 5505

Pulse amplitude: 20 - 200V in 0.5V steps

the optional RM 5505 has

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.
