Low-Cost RF Vector Signal Generation for Wireless Communications Test
Agilent Technologies complex modulation generation with low cost arbitrary waveform generators - Agilent's trueform architecture for wireless applications.
Digitally modulated signals fill space and travel through almost every wired and optical network. Today, almost all wireless services use a plethora of complex carrier modulation schemes. The continuous improvement in modulation technologies, components, and advancements in error-correction codes has increased channel capacity close to the fundamental limit as set by the Shannon-Hartley Theorem.
Capacity and efficiency have been improved even more through the development of new transmission strategies such as MIMO antenna technology and the implementation of extremely flexible multiple access schemes in the time, frequency, and code domains.
Additionally, more and more products and services with decreasing prices rely on the capability of one or more wireless technologies to operate properly. This level of complexity and interoperability is made possible only through extensive testing during all the phases of the life of a product or service – from basic technology research to device manufacturing or network deployment.
Test equipment flexibility is paramount to successfully address those needs. The overall cost of test equipment is also important so team leaders can make sure the equipment is available to all engineers throughout the entire project. 
Read this white paper  to learn how the Agilent  33500B Series Trueform waveform generators can be applied to generate today's complex modulated signals. These Trueform waveform generators offer a very cost-effective solution for generating many modern, complex, baseband IQ digital communication signals and digital wireless protocols like W-CDMA, DVB and OFDM.
