Description / Abstract:
This part of SAE J1113 specifies the direct RF power injection
test method and procedure for testing electromagnetic immunity of
electronic components for passenger cars and commercial vehicles.
The electromagnetic disturbances considered in this part of SAE
J1113 are limited to continuous, narrowband conducted RF
energy.
This test method is applicable to all DUT leads except the RF
reference ground. The test provides differential mode excitation to
the DUT.
Immunity measurements of complete vehicles are generally only
possible by the vehicle manufacturer. The reasons, for example, are
high costs of a large absorber-lined chamber, preserving the
secrecy of prototypes or the large number of different vehicle
models. Therefore, for research, development, and quality control,
a laboratory measuring method for components shall be applied by
the manufacturer. This method is suitable over the frequency range
of 250 kHz to 400 MHz.
This direct RF power injection test is particularly effective
when used as part of the engineering development of the electronic
component (at the prototype PCB level) where the line by line
diagnostic capabilities of this test facilitate costeffective
circuit board level improvements in the RF immunity performance of
the module or component.
