Review of MIL-STD 461 RS101– Radiated Susceptibility, Magnetic Field and RS103 Radiated Susceptibility, Electric Field

This article discusses RS101 and RS103, including the updates contained in MIL-STD-461 revision “G”, the current revision.  These tests quantify the ability of a device to tolerate undesired signals present as a field at the device and associated cables.  The field has the potential of coupling the interference into the device circuitry and cause performance degradation or device damage.

These test methods have been a part of the MIL-STD-461 test program from the onset using RS01 (Magnetic Field), RS02 (Magnetic Induction Fields), RS03 (14 kHz-10 GHz electric field) and RS04 (14 kHz-30 MHz Parallel Plate Electric Field) numbering.  MIL-STD-461 assigned applicability and test levels for various applications.  In addition, reference is made to MIL-HDBK-235 to determine the anticipated environment for establishing test levels for any particular application.

RS01 magnetic field testing was accomplished much like today over the 30 Hz to 30 kHz frequency range with a radiating loop placed 5 cm from the test article.  A 1-ohm resistor was …
