German Metrology Institute Cites EMI Impact on Measurement Systems
The German Metrology Institute, or Physikalisch-Technische Bundesanstalt (PTB), has posted an article detailing the impact of electromagnetic interference on modern measurement systems. This article also includes an announcement of a portable device that it has developed to solve this problem. The gist of this article includes two well known facts. First, we no longer rely on … [Read more...]
Antenna Suite Targets HIRF Testing Applications
A suite of three high-gain, high-power microwave horn antennas from AR RF Microwave are intended for use in DO 160 HIRF (high intensity radiated frequency) testing. These antennas provide even more options for varying test conditions. The AT4444 provides 2 to 4 GHz/ 1000 watts CW / 17-kw pulse input power while the AT4446 provides 4 to 6 GH / 800 watts CW /15-kW pulse power. … [Read more...]
Antenna Mast Crafted for EMI/EMC Testing
The AM-400 from Com-Power Corporation is an antenna mast well suited to making EMC measurements in an OATS (open air test site) or in test chambers. The height of the antenna can be varied from one to four meters during measurement as required by commercial EMC specifications. The mast is constructed using fiberglass tubes and grating material. These were chosen because they … [Read more...]
Portable, Folding Biconical Antenna Performs Site Attenuation Measurements
The SAS-542 Folding Biconical Antenna from A.H. Systems was the first EMC antenna designed for portable compliance testing applications. Product features include a frequency range of 20 MHz to 330 MHz, maximum continuous power of 1 watt, impedance of 50 Ω, and a maximum radiated field of 2 V/m. These antennas are individually calibrated (1-, 3- and 10-meter calibration … [Read more...]

Broadband EMC Test Antenna Target Emissions and Immunity Testing
The JB Series antennas from Sunol Sciences Corporation are compact instruments for EMC emissions and immunity testing. The antennas’ broadband characteristics allow operation over a wide frequency range—a necessity in automated test environments. The antenna boom is made from a custom aluminum extrusion that reduces the number of parts at the nose, resulting in stable feedback … [Read more...]
Extremely Broadband Antennas Crafted for Accurate Measure of E-Field Intensity
The SAS Series from Antenna Research Associates (ARA) include extremely broadband portable receiving antennas crafted specifically for accurate measurement of electrical field intensity. They are well suited to wideband emissions testing and spectrum surveillance applications. Integral active networks provide performance over the entire frequency range of operation. Although … [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...]
NASA’s Kepler Spacecraft Slated for EMC Testing
NASA’s planet-hunting Kepler mission, scheduled for launch in 2009, recently survived an extreme temperature test. The thermal vacuum test is part of a series of environmental tests the spacecraft will undergo before it soars into space aboard a Delta II rocket from Florida’s Caper Canaveral Air Force Station. The test, which was performed at Ball Aerospace and Technologies … [Read more...]
