We delivered a Test Station to NAVSEA Naval Surface Warfare Center (NSWC) in Crane, Indiana. The Test Station contains many state of the art features, including:

• The latest Agilent Network Analyzer (PNA-X Series)
• A 10-port Extension for measuring multi-port S-parameters
• An R. A. Wood Associates custom-designed RF Load Box/Chassis for testing high power RF devices
• Rack mount computer, keyboard, and monitor with digital I/O, GPIB interfaces
• A PXI chassis with fiber optic interface, digital I/O, serial interfaces, temperature monitors, and GPIB interfaces
• LabVIEW Software utilities to support setting up the Network Analyzer, retrieving S-parameters from the Network Analyzer, controlling the RF Load Box, and controlling other measurement equipment in the Test Station

This was a very exciting project, and we really enjoyed working with our customer on this program. The complete project was delivered within 7 months of the order being placed. Great job everybody!
