Emission Testing

Immunity Testing
These automotive electrical disturbances occur regularly in the vehicle primarily due to switching on and off of various vehicle components from the starter motor to electrical and electronic systems.
There are both emissions and immunity tests required by the standards, of which there are many. The main standards like ISO 7637-2 and ISO 16750-2 define both how these pulses must be simulated and how they are measured and with what limits. The vehicle manufacturers who are ultimately responsible often take these requirements and expand or modify them.
For immunity testing you need a transient generator (NSG 5500), some kind of coupling network, a battery simulator (PA 5840 or PA 5740) and function generator (NSG 5600).
For emissions testing the AES 5501 includes just about everything you need, switches, artificial network, even the oscilloscope probe.
Many OEM requirements include ESD testing similar to ISO 10605, for which an NSG 438 is highly recommended.

-
Designed in accordance to Ford standard EMC-CS-2009
-
Transients disturbances CI 220 A and C pulses
-
CI 260 waveform F
-
User replaceable relays
Description
The NSG 5071 is designed exactly in accordance with EMC-CS-2009.1 for test CI 220 pulses A1, A2-1, A2-2, C1, C2 and RI 130 using an inductive/relay transient generator test circuit. The NSG 5071 also features the CI 260 Waveform F in this test circuit which uses the same type of relay. This test circuit is defined in annex F for the A, C pulses and RI 130 and figure 19-10 for CI 260 Waveform F.
The basic philosophy of this test circuit is better reproducibility of actual switching transients. The reproducibility of this test circuit comes not from the output characteristics as in traditional conducted automotive immunity tests, but from a fixed design of the generator using several pre-defined components. Many of these components are defined in the standard as “critical” with no substitutions allowed. These components are used as required in the standard.
