At the MTT-S show this year National Instruments introduced the NI Measurement Suite for Fixed WiMAX (IEEE 802.16-2004), a software suite that can be used to configure software-defined PXI RF measurement systems. With this suite, engineers can test WiMAX base stations and mobile subscriber stations as well as components such as transceivers, power amplifiers and other RFICs.
Proper timing components will not only produce optimal performance of your end design, but also deliver the most cost effective solution. By NDK America, Inc. Figure 1. Intelligent transportation systems could be use in accident avoidance between cars as signals would detect encroaching danger and automatic braking would be applied....LISTED UNDER: Crystals
Silicon Clocks announced its breakthrough CMEMS-ZeroThermal passive temperature compensation technology that enables MEMS resonators to exhibit comparable temperature stability to quartz crystals, while simplifying oscillator design and reducing power and circuit size. First-generation MEMS oscillator solutions use resonators whose frequency varies quickly in response to temperature variations, typ.LISTED UNDER: Crystals
A receiver's position accuracy is a fundamental challenge of satellite navigation system. As a result, GPS receiver designers must perform a combination of measurements to ensure the device will perform as expected. David A. Hall, National Instruments Geocaching involves discovering various "caches" whose coordinates can be found on the Web and whose contents are located all over the world.
As wireless standards continue to evolve, software-defined ?test systems will continue to evolve with them. By Luke Schreier, National Instruments As the proliferation of wireless standards continues, the idea of using software-defined measurement capability has become a necessity as opposed to a matter of click to enlarge Figure 1.
