Alternative (Ecological) Method for Measuring Electronic Product Immunity to External Electromagnetic Fields
2023-03-20
CURRENT
ARP5889A
This method is used to define the immunity of electric and electronic apparatus and equipment (products) to radiated electromagnetic (EM) energy. This method is based on injecting the calibrated radio frequency currents (voltages) into external conductors and/or internal circuits of the product under test, measuring the strength of the EM field generated by this product and evaluating its immunity to the external EM field on the basis of the data obtained. The method can be utilized only when it is physically possible to connect the injector to the conductors and/or circuits mentioned before.

In-House Verification of EMI Test Equipment
2022-06-24
CURRENT
AIR6236A
This AIR provides guidance to the EMI test facility on how to check performance of the following types of EMI test equipment: Current probe Line Impedance Stabilization Network (LISN) Directional coupler Attenuator Cable loss Low noise preamplifier Rod antenna base Passive antennas All performance checks can be performed without software. A computer may be required to generate an electronic or hard copy of data. This is not to say that custom software might not be helpful; just that the procedures documented herein specifically eschew the necessity of automated operation.

Stripline Test Method to Characterize the Shielding Effectiveness of Conductive EMI Gaskets up to 40 GHz
2022-01-21
CURRENT
ARP6248
The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI conductive gasket materials and EMI conductive gaskets. Depending on the materials used for the construction of the measuring setup, the EMI conductive gaskets can be characterized against various joint surfaces. This standard will directly provide shielding effectiveness values up to 40 GHz, and will also be applicable for small samples of conductive EMI gaskets.

Cabling Guidelines for Electromagnetic Compatibility
2009-11-22
CURRENT
AIR1394A
These cable practice recommendations tend toward design guidance rather than standardization. EMC achievement tests can be standardized, but the means for achievement should not be constrained. The material can best be described as an essay on cabling, and the theme is that a cable is just a part of a complete circuit, the interconnect circuit. Cable EMC performance is thus determined largely by circuit design; it is unrealistic to expect cabling techniques to compensate for improper impedance, symmetry or waveform in the circuit.
