RF Measurement Architectures
The Electromagnetic Spectrum is a finite resource and its use is rapidly expanding. Unencumbered access to spectrum has been, and continues to be, critical to many government and commercial systems. As existing RF systems evolve and new communication systems are deployed, the need for additional spectrum bandwidth continues to grow. For example, to support the demand for broadband access, the number of wireless bands for Long Term Evolution (LTE) has increased from 11 to 48 since 2011. The continued coordination and future allocations are foreseen as federal spectrum is released. With federal mandates and initiatives, such as the 500 MHz of federal spectrum released for commercial use by 2020, the impact to spectrum monitoring equipment and the role of spectrum management must also evolve.
This talk wiill cover the different functions of the traditional RF measurement instrument architectures and their role in spectrum monitoring. The basic spectrum analyzer architecture is discussed as well as the modern digital monitoring receiver. Unlike the role of a typical spectrum analyzer, the monitoring receiver has an operational environment that is quite different than a typical measurement instrument. In consideration of the operational environment of a monitoring receiver, the international requirements for modern monitoring receivers are defined by the International Telecommunications Union Radio communications working group (ITU-R), and outlined in the ITU Handbook Section 3.3.5. In the US, the NTIA Redbook, Manual of Regulations & Procedures for Federal Radio Frequency Management, references the work of the ITU-R. From signal detection, classification, and analysis to radiolocation tasks, the challenges of spectrum monitoring in a crowded and dynamic environment have had a profound impact on modern architectures design and use.

RF Measurement Architectures
This talk describes the brief review of RF measurement tools, such as: spectrum analyzers, signal analyzers, and receivers. There are two architectures largely grouped as analog (swept) and digital (stepped). While much of the capability of a modern analog RF measurement architecture is supported by digital processing, the functions do not change widely. However, most of the innovation and advantages of the modern digital RF measurement instrument allow a significant functional advantage for spectrum monitoring. The analog architecture does not capture the phase information of a signal, and thus is not suitable for the monitoring or decoding analysis of modern digital signals
