Michael Millhaem, Principal RF Application Engineer Keithley Instruments, Inc. Test equipment manufacturers are constantly challenged to develop new solutions for testing their customers’ latest devices, but they’ve traditionally developed specialized hardware to meet this challenge....
This clearly written and informative technical paper examines the WiMAX frame structure, permutation zones and bursts. To illustrate radio complexity and familiarize the reader with digital demodulation tools, the example given in this paper focuses solely on demodulation measurements of a Mobile WiMAX signal with data bursts. Selection of a map file, display and analysis of all data bursts in the map are among the topics presented in this paper. Additionally, the paper discusses how to perform modulation quality measurements on the uplink signal as well.
There is a wide variety of coaxial connectors and cables available for use in the RF and Microwave spectrum. While often not much thought is given to these essential components, a misstep here can result in undesirable system degradation.
