ELECTROMAGNETIC COMPATIBILITY MEASUREMENT PROCEDURES FOR INTEGRATED CIRCUITS—INTEGRATED CIRCUIT RADIATED EMISSIONS MEASUREMENT PROCEDURE 150 KHZ TO 1000 MHZ, TEM CELL

Scope
This SAE Recommended Practice defines a method for measuring the electromagnetic radiation from an integrated circuit. The method uses a standardized IC test board containing the IC being evaluated mounted to a mating port cut in the top or bottom of a 1 GHz TEM cell. The standardized test board controls the geometry and orientation of the operating IC relative to the TEM cell and eliminates any connecting leads within the cell (these are on the back side of the board which is outside the cell). One of the TEM cell feeds is terminated with a 50 Ω load and the other one is connected to the input of a spectrum analyzer which measures the RF emissions over the frequency range of 150 kHz to 1000 MHz emanating from the integrated circuit and impressed onto the septum of the TEM cell (see Figure 1).

Electromagnetic Radiation (EMR) Task Force
The Electromagnetic Radiation (EMR) Standards Committee encompasses the technology of electrical/electronic system electromagnetic radiation and the associated processes, test methods and limits with particular attention given to the protection of radio reception. Complete vehicles, devices (as defined in SAE J551-1) and components are included in the scope. Vehicles include internal combustion and electric driven surface vehicles and boats (under 15 m in length), but exclude trains and trolleys.
Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
