Seven Fundamental Considerations for Selecting EMI Filters
By Rigoberto Rios, Jorge Varela, and Amanda Ison Virtually every electronic device is subject to and, to at least some degree, must be protected from electromagnetic interference (EMI), or electrical noise. EMI is generated by both naturally occurring and engineered sources ranging from solar flares to cell phones, and, if left unmitigated, diminishes the integrity and … [Read more...]

Circuit Level Design and Test for the MIL-STD-461 200 V/m RS103 and the DO-160 Radiated Susceptibility Test at 200 V/m
Introduction For Army, Navy, and Air Force military equipment and DO-160 commercial aircraft avionics, radiated susceptibility test levels as high as 200 V/m may be specified. As always, it is better to design immunity to the test levels into equipment than to wait until equipment is completed and then perform tests. This article assumes the worst-case qualification test … [Read more...]
MIL-STD-461G Passive Device Calibration Review
The Requirement: When MIL-STD-461 revision “G” was issued, I believed that the answer to many of my measurement equipment calibration issues had been solved. Right there in the “Calibration of measuring equipment” paragraph the requirements clearly stated: After the initial calibration passive devices such as measurement system antennas, current probes, and LISNs, require no … [Read more...]
Review of Induced Signal Susceptibility Testing—DO-160 Section 19
The Issue Induced signal susceptibility has been a factor in electronic equipment performance since the dawning of voltage and current. Often referred to as crosstalk, the undesired coupling of one circuit’s signals to another may result in interference that degrades the integrity of either signal. This article examines the testing process prescribed by RTCA DO-160 Section … [Read more...]
