Introduction MIL-STD-461G, released in December 2015, added a test for Personnel Borne Electrostatic Discharge (ESD). Prior to this release, this type of test for electronic systems and sub-systems was managed at the system level under MIL-STD-464C released in 2010. Both of these standards contain similar requirements. MIL-STD-461G provides the details on testing and … [Read more...]

Review of MIL-STD 461 CS114– Conducted Susceptibility, Bulk Cable Injection
Introduction This article discusses CS114, including the updates contained in MIL-STD-461 revision “G”, the current revision and the associated nuances that lead to test errors. The fundamental idea behind CS114 testing is to simulate currents induced into cabling from electromagnetic (EM) fields from high level emissions, intentional or unintentional. This test allows an … [Read more...]
Review of MIL-STD 461 RS101– Radiated Susceptibility, Magnetic Field and RS103 Radiated Susceptibility, Electric Field
Introduction 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 … [Read more...]
Review of MIL-STD 461 RE101– Radiated Emissions, Magnetic Field and RE102 Radiated Emissions, Electric Field
Introduction This article discusses RE101 and RE102, including the updates contained in MIL-STD-461 revision “G”, the current version. These tests quantify undesired signals being radiated into the air from a device and the associated cables. If unchecked, these signals couple onto other equipment cables or may enter into the other equipment chassis and onto internal … [Read more...]
Review of MIL-STD 461 CE101– Audio Frequency Currents and CE102 Radio Frequency Potentials – Power Leads
Introduction This article discusses CE101 and CE102, including the updates contained in MIL-STD-461 revision “G”, the current version. The test title for CE101 “Conducted Emission Audio Frequency Currents, Power Leads” and for CE102 “Conducted Emissions Radio Frequency Potentials, Power Leads” provide insight into the test frequency range and methods of measurement. These … [Read more...]
Review of MIL-STD 461 CS101– Low Frequency Susceptibility – Power
Introduction This article reviews MIL-STD-461 CS101 including the updates contained in revision “G” the current version. The test title “Conducted Susceptibility, Power Leads” pretty well defines the test, where interference is applied to the power input of the Equipment Under Test (EUT). During application of the interference the EUT is monitored to verify acceptable … [Read more...]
