VectorStar-based 4-Port VNA Solutions Deliver Fast and Accurate S-Parameter Measurements
Tue, 08/11/2009 - 12:53pm
Anritsu Company introduces the MN469xA series 4-port test sets for use with its VectorStar MS4640A vector network analyzer (VNA). The development of the MN469xA series takes advantage of VectorStar's 70 GHz high-performance, proven switching technology to produce the high accuracy and wide dynamic range necessary to conduct 16 fully corrected S-parameter measurements with speed and accuracy. The MN469xA has been developed for today's highly integrated multiport assemblies and common three-port devices, such as combiners, diplexers, and couplers. The configuration is also well suited for measuring balanced two-port devices, such as high-speed transmission line backplanes, connectors, cables, balanced amplifiers, baluns, and transceivers. The VectorStar multiport solution provides 10 MHz to 20/40/70 GHz 4-port capability using an external test set driven by the base VNA. This flexibility allows the removal of the test set for uncompromised 2-port measurements or for use with multiple VNAs. The architecture is suited for single-ended devices, balanced passive devices, and balanced linear active devices.
