A vector network analyzer is an essential tool for the characterization of antennas. This application note provides an overview of near and far-field measurement techniques. There are challenges to either method, and a solid understanding of these will be helpful to achieve superior measurement results.
Systems utilizing high-speed digital signals are ubiquitous and necessary parts of everyday life. For the designer or informed consumer, it is important to understand how to analyze transport media to obtain optimal performance. This article examines digital signal analysis methodology using a VNA.
A VNA measures reflection coefficients of RF devices and systems. To be very meticulous, each measurement should be accompanied by an uncertainty with a specified statistical confidence interval. To understand the measurement uncertainty, or accuracy, it is important to understand the contributing factors, which are explored in this white paper.
The 804/1 is an 8 GHz, full-size analyzer providing lab grade performance in a 19-inch chassis, including both 2-port configuration and direct receiver access. All devices are ATE compatible, rack mountable, and easy to program and share between multiple users.
