Review of MIL-STD 461 CS118 – Electrostatic Discharge

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 MIL-STD-464C established the […]

Review of MIL-STD 461 CS114– Conducted Susceptibility, Bulk Cable Injection

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 evaluation in the […]

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 […]

Review of MIL-STD 461 RE101– Radiated Emissions, Magnetic Field and RE102 Radiated Emissions, Electric Field

RE01 (RE04) covered the frequency range of 30 Hz to 50 kHz with the magnetic loop antenna located 1-meter from the Equipment Under Test (EUT). The limit was in dBpT (dB referenced to 1 picotesla) terms indicating a flux density measurement. RE02 covered the frequency range of 14 kHz to 10 GHz for narrowband (NB) […]
