Automotive test pulse verification under loaded conditions
 
In accordance with the pulse verification requirements given in Annex C of     7637-2:2011 and Annex A of     16750-2:2012, test pulses generated by automotive transient generators need to be verified both under no-load (open circuit verification)'s internal source impedance defined for the corresponding test pulse.
The CA     is a resistor box containing all load resistors required to verify micropulse and load dump generators according to international standards and manufacturer requirements.

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     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     7637-2 and various manufacturer specifications

20.0 Ohm for verification of pulse 1 as per     7637-2 and various manufacturer specifications.

All load resistors are non-inductive and have a tolerance better than 1%.
