The Agilent E5071B (300 kHz to 8.5 GHz) model offers integrated 2, 3, or 4 test ports, and enable various component measurements from 2-port filters to multiport devices like duplexers and couplers.
The ENA offers built-in balanced measurements, matching circuit simulation, and port characteristic impedance conversion. In addition, the ENA provides frequency-offset and harmonics measurement capabilities. These functions increase engineering efficiency by delivering fast and accurate measurement results for the most advanced RF components, such as balanced SAW filters, differential amplifiers, mixers, converters, and front-end modules.
