7 Hints for Making Innovative Signal Source Measurements in Wireless RF Design and Verification Using the Signal Source Analyzer Application Note E5052A Signal Source Analyzer (SSA) Breaks the Current Measurement Paradigm and Defines an Entirely New Class of Instrument Importance of RF Design and Verification in Today's Wireless Communication Systems Market demands for today's Table 1. Examples of technical challenges to meet market demands wireless communications Market demands Technical challenges systems To achieve higher data rates... Higher order and/or new Today's wireless communications modulation/demodulation schemes systems are required to simultane- (compressed decision point in the ously provide better service quality constellation domain like 64 QAM/CDMA, and lower costs. These expectations OFDM modulation, etc.) are becoming increasingly difficult for For more capacity and efficient spectrum Higher frequency operation RF design engineers to accomplish reuse...
