International Microwave Symposium 2010: RF vendors look for edge in recovery
International Microwave Symposium, May 23-28, Anaheim, CA; IEEE, www.ims2010.org.

A bustling exhibit floor gave vendors a chance to show off their wares to attendees of the International Microwave Symposium. Greg Peters, VP and GM of the component test division of Agilent Technologies, said business has recovered to within 85% of its prerecession peak in 2008. On the show floor, Agilent highlighted products such as its new portable N9923A FieldFox RF vector network analyzer, which provides 0.01-dB/°C measurement stability and offers an integrated QuickCal calibration capability. Also in a handheld format, the company demonstrated its V3500A RF power meter. Peters said such instruments can serve in edge-device applications (see "Embedded and edge devices offer test opportunities").
Noise Extended Technologies (Noise XT) made its first US appearance since its buyout by the employees of Aeroflex-Europtest. Guillaume de Giovanni, president of the Elancourt, France, company, said Noise XT now has a single focus on addressing customers' noise-measurement problems. On the show floor, he demonstrated the DCNTS (Dual Core Noise Test System), a two-channel phase and amplitude noise analyzer designed with a dual demodulator architecture that allows the test system to use cross-correlation to cancel its internal noise.
Jon Leitner, product manager at Rohde & Schwarz, and Sherry Hess, VP of marketing at AWR, described interoperation between AWR's design environment and R&S instruments. The companies have teamed up to remove the boundary between simulation and test and to support a parallel design and verification flow involving hardware-in-the-loop simulation. They also described how the AWR Connected tool in conjunction with R&S WinIQSIM2 simulation software allows RF and baseband designers to access standard-compliant signals for all modern communication technologies.
Representatives of Giga-tronics were on hand to discuss microwave switching systems. They recommended "test your DUT, not your system" and advised that your switch bandwidth be at least 0.35 divided by your steepest rise time. They also suggested using a star configuration, which in a four-pole format can provide six possible signal paths, instead of the common SP4T configuration, which has only four signal paths.
National Instruments demonstrated its new software for IEEE 802.11n wireless LAN testing, the NI WLAN Measurement Suite 2.0 (see" NI advances IEEE 802.11n wireless LAN test"). David Hall, RF product marketing manager at NI, said the suite also delivers the industry's fastest speed for error vector magnitude and spectrum-mask measurements.
Anritsu introduced its 0.1-Hz to 70-GHz MG3690C series RF/microwave signal generators (see "Signal-generator family reaches 70 Ghz"). Bob Buxton, marketing manager in the general-purpose business unit of the company's microwave measurement division, said the generators combine best-in-class phase noise and broad frequency generation.
