EMC software takes center stage
IEEE Symposium on Electromagnetic Compatibility, August 7–10, Portland, OR. www.emcs.org.
EMC design and test software was in abundance at this year’s symposium. “EMC simulations are simply tests done with computers,” said Bruce Archambeault, distinguished engineer at IBM. Software appeared from IBM (www.mossbayeda.com), Ansoft (www.ansoft.com), Advanced Electromagnetics (www.aemi-inc.com), ScanCAD (www.scancad.com), Zeland Software (www.zeland.com), EMS-Plus (www.ems-plus.com), NEC (www.emistream.com), SimLab Software (www.simlab-emc.com), and Applied Simulation Technology (www.apsimtech.com).
Software from Flomerics (www.flomerics.com) simulates PCB emissions. Comsol (www.comsol.com) also exhibited its general-purpose modeling software that includes electromagnetics. Quantum Change (www.quantumchange.com) offers software that automates EMC measurements in the lab, and Traxstar Technologies (www.traxstar.com) offers software for managing EMC labs.
Agilent Technologies (www.agilent.com) announced a return to the CISPR EMC compliance market when it previewed a CISPR-compliant preselector for frequencies up to 1 GHz. Rohde & Schwarz (www.rohde-schwarz.com) introduced a new FFT scan option for its EMI receivers that reduces measurement time. A management buyout of the Test Systems Division of Schaffner (www.schaffner.com) will result in a new company. The new company, which has not yet been named, will be headquartered in Luterbach, Switzerland; and Berlin, Germany.
TECHNICAL SESSIONS
This year, the technical sessions included papers that covered signal integrity. In one session, Antonio Ciccomancini of CST simulated the physical parameters of a 16-layer backplane over the 0–20 GHz range. In the “Extreme EMC” session, Ron Brewer discussed how today’s spacecraft are tested to yesterday’s EMC standards. Johan Catrysse gave a presentation about IEEE 1302, a standard that covers test methods for characterizing EMI shielding gaskets. Gang Feng of the University of Missouri-Rolla discussed a method for measuring EMI coupling paths in electronic systems. Robert Johnk explained how NIST worked with General Motors to characterize the company’s automotive EMC test facility to provide uniform fields for immunity testing.
Brian Jones described how Britain is adjusting to the new EMC Directive, which becomes effective next year and receives full enforcement on 2009. Hirayr Kudyan discussed how he performs measurements on a system’s power bus to predict the product’s EMC performance before the product is completely designed. Ken Wyatt demonstrated the effects of ESD on electronic circuits. He creates ESD discharges to show how today’s high-bandwidth oscilloscopes reveal more about ESD waveforms than was known when test standards were written.

Voice and video continue to grow
VON Fall 2006, Boston, MA, September 11–14, 2006. Pulver Media. www.von.com.
VON (which originally stood for Voice On the Net) has grown from a niche show into one that now boasts 250 exhibitors. Although voice over IP (VoIP), is still growing, video has really fueled VON’s growth. The Fall 2006 edition of VON saw the emergence of IP Multimedia Subsystem Networks—a protocol that merges IP services with a range of access networks
Spirent Communications (www.spirentcom.com) introduced the Spirent Protocol Tester with predefined test cases for testing IP Multimedia Subsystem (IMS) core-network elements. As part of the announcement, Reef Point Systems demonstrated its security for voice and video calls that use IMS to provide network access. Tektronix (www.tektronix.com) announced Spectra2|VQM version 2.0 software for its Spectra2 network tester, which early IMS adopters can use in network test. Spectra2|VQM version 2.0 adds video-quality testing to its voice capabilities.
Radcom (www.radcom.com) announced Omni-Q for IPTV, an instrument that monitors IPTV networks for network quality (jitter and packet loss), video stream quality, video decoding, video stream statistics, and other parameters. Ixia (www.ixiacom.com) added capabilities to its Optixia modular test platform that support voice, video, and data testing.
