You are cordially invited to a Technical Presentation by the IEEE Huntsville EMC Chapter. Mr. John Andresakis of Oak-Mitsui Technologies, will present “Use Of Buried Capacitance Layers In Printed Circuit Boards: Performance And Lessons From A Real World Example”. Meal Sponsor: Mr. Mike Kirk, Agilent Technologies, providing “Fried Chicken With All The Fixin’s”
Abraham Lincoln is quoted as saying that if he had eight hours to chop down a tree, he would spend six of those hours sharpening his axe. This presentation is about replacing the axe with a chainsaw. Spectrum analyzer surveys of platform (aircraft, ground vehicles, ships) antennas are the ultimate check that RFI has been properly controlled. As envisioned in MIL-STD-464, an analyzer is connected to a platform antenna and the antenna band is swept, looking for RFI signals. This technique fails when the antenna must be tuned for each frequency of operation. In the past, this was only the case for HF, but today multi-band antennas covering 30-512 MHz are also tunable. The presenters have developed a hardware solution that allows broadband sweeping of a tuned antenna from 2 – 512 MHz (COMM Bands: HF, VHF-FM, VHF-AM, and UHF-AM) without tuning.
