Agilent Technologies Inc. announced the extension of its source-corrected noise-figure measurement capability in PNA-X network analyzers to 43.5 and 50 GHz, while continuing to maintain the highest noise-figure measurement accuracy in the industry. Built directly into the Agilent PNA-X, the technique provides a complete single-connection, multiple-measurement capability for R&D and manufacturing engineers developing and testing low-noise transistors, amplifiers, frequency converters and transmit/receive modules.
