简单介绍

In accordance with the pulse verification requirements given in Annex C of ISO 7637-2:2011 and Annex A of ISO16750-2:2012, test pulses generated by automotive transient generators need to be verified both under no-load (opencircuit verification) and loaded conditions with specified loads.

In accordance with the pulse verification requirements given in Annex C of ISO 7637-2:2011 and Annex A of ISO16750-2:2012, test pulses generated by automotive transient generators need to be verified both under no-load (opencircuit verification) and loaded conditions with specified loads. The values of the load resistors is specified and are equal tothe generator's internal source impedance defined for the corresponding test pulse.The CA ISO is a resistor box containing all loads

SELECTION OF LOAD RESISTORS

The set of load resistors has been well selected in order to

meet the wide range of source resistors specified in

various national/international standards and vehicle

manufacturer specifications.

The following load resistors are most used:

0.5 Ohm for Load Dump pulse verification as per a number

of manufacturer specifications

1.0 Ohm for Load Dump pulse verification as per a number

of manufacturer specifications

2.0 Ohm for verification of pulse 2a and pulse 5 as per ISO

7637-2 and various manufacturer specifications

4.0 Ohm for verification of pulses 1, 2 and Load Dump

pulse 5 as per various manufacturer specifications

10.0 Ohm for verification of pulses 1 and 2 as per ISO

7637-2 and various manufacturer specifications

20.0 Ohm for verification of pulse 1 as per ISO 7637-2 and

various manufacturer specifications.

All load resistors are non-inductive and have a tolerance

better than 1% as per standard requirements. They show

sufficient power dissipation for the transient pulse energy.
软件

The CA ISO verification box is directly plugged into the

CDN outputs of the transient generator. The required load

resistor is selected by the bridge connector. The waveform

across the load resistor is best measured by a 100:1

voltage probe with sufficient bandwidth and voltage

capability. EM TEST recommend a bandwidth of 20MHz

minimum and a voltage measuring capability of 1,000V
