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...]
AR Releases New High-Power Amplifier, Plus Enhancements to Three Classic Designs
AR is pleased to announce the new, high-power 6000W1000 amplifier, a prime example of AR’s ability to provide high power over the 80-1,000 MHz frequency range. AR has also upgraded three Class A solid-state, broadband amplifiers; models 1000S1G2z5B, 2500A225B, and 5000A225B. The enhanced models power a wide range of applications, including automotive, military, and aviation. … [Read more...]
New AR Amplifier Spans 10 kHz to 400 MHz Range With 1000 Watts of Power
AR's new amplifier, Model 1000A400, provides CW power up to 1000 watts, covering 10 kHz-400 MHz. In conjunction with AR's accessories and antennas, the 1000A400 is optimal for reaching today's higher radiated and conducted susceptibility test levels, such as the increased conducted immunity test levels of composite aircraft in the frequency range of 10 kHz-400 MHz, along with … [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...]
