The Agilent E5063A series of network analyzers is available in multiple frequency options starting from 500 MHz to 18 GHz. It offers a balance of performance and cost. It offers optimized performance and functionality for testing simple RF passive components, such as handset/BTS antennas, RF cables and filters. It can also be used in R&D for evaluation of RF passive devices and dielectric materials. The network analyzers have 2 ports and excellent RF performance, including trace noise of 0.002 dBrms and the stability of 0.01 dB/degC. This feature helps reduce test cost without sacrificing quality. Using the E5063A with U1810B USB RF switch, engineers can build an economical multi-DUT test solution for testing four antennas with a single instrument, further reducing cost of test.
