A proposed set of new test methods may provide more accurate attenuation data Kermit O. Phipps, Philip F. Keebler, Bradford R. Connatser Many commercial and industrial electrical environments contain equipment that is sensitive to radio-frequency (RF) interference. Theft detectors, digital sensors, and medical-telemetry systems have all been known to malfunction in the … [Read more...]
EMC in Space …
Successfully dealing with EMC in space systems requires strong EMC engineering Daryl Gerke, PE, and William Kimmel, PE Many of us in the EMC business came of age during the “space race” of the 1950s, 60s, and 70s. We well remember names like Sputnik, Mercury, Gemini, and of course, Apollo. Some of us in the EMC business have even been fortunate enough to spend some (or all) or … [Read more...]

Colorado DOT Will Use EM-Based Technology to Reduce Elk-Car Collisions
This week, the Colorado Department of Transportation (DOT) launched a new wildlife detection system along a stretch of U.S. 160 east of Durango in southwestern Colorado, an area where officials indicate that 70 percent of all reported collisions involve wild animals. Fencing was ruled out as a viable option, and lasers or microwaves were too easily triggered by motion from snow … [Read more...]
New Probe Accurately Measures Pulse Fields in Radiated Immunity Testing
Model PL7004 (800 MHz – 3.6 GHz / 80 – 800 V/m) from AR RF Microwave Instrumentation is a new laser-powered E-field probe for measuring the E-fields in radiated immunity testing and in GMW3097 and Ford ES-XW7T-1A278-AC automotive radar pulse tests. This device has been crafted to measure the RMS value of the “on time” of a pulsed electric field. Each probe is supplied with … [Read more...]
Kits Include All Needed Antennas for Shielding Effectiveness Testing
The AK-285R and the AK-285T from A.H. Systems are antenna kits that include all the antennas required for shielding effectiveness testing. Included are a log periodic antenna, a bi-conical antenna, an active monopole/loop antenna, and a double ridge guide horn antenna. Each component has a specific storage compartment in the carrying case, thus forestalling possible loss or … [Read more...]
Solving the Galvanic Corrosion Issue in EMI Shielding
Tungsten carbide/aluminum composite particles inhibit galvanic corrosion of aluminum. Harry Fuerhaupter, Potters Industries, Inc. ABSTRACT An ongoing issue in the design of reliable EMC shielding is galvanic corrosion of aluminum. How can an aluminum frame be protected from galvanic corrosion if it contacts an EMI gasket containing non-aluminum particles? Chromate conversion … [Read more...]
Automotive Transient Emission Test System Complies with ISO 7637-2
The new AES 5500 automotive transient emissions system from Teseq is the only complete solution for emission testing that is compliant to ISO 7637-2. This compliance makes this system the logical choice for testing the compatibility of conducted electrical transients of equipment installed in passenger cars and light commercial vehicles fitted with a 12-V electrical system.
