RF Testing in the Aerospace Industry
USB vector network analyzers (VNAs) are a better fit for secure environments than traditional instruments. Taking traditional network analyzers in and out of secure environments is a lot of work, requiring removable hard drives, data purging procedures and oversight over those data purging procedures. With USB VNAs the computer that stores and processes the data is separate from the measurement module, so, as long as the computer stays in the secure area, all data concerns are eliminated, and the data measurement module can easily move between laboratories and sites. The measurement module has only volatile memory, so no data is retained, and the separate PC can be made secure following standard security protocols.
