GORE VNA Microwave/RF T T As Improved VNA performance with precise measurements GORE VNA Microwave/RF Test Assemblies set the industry standard for vector network analyzers (VNAs) through 67 GHz. Constant and/or highly repetitive movement of cables can compromise the measurement precision of high-performance VNAs. Leading manufacturers choose GORE VNA Microwave/RF Test Assemblies because of the improved performance they see in their equipment. These test assemblies are specifically engineered to provide the most precise VNA measurements under laboratory conditions. They deliver the highest accuracy and the greatest time interval between recalibrations. GORE VNA Microwave/RF Test Assemblies have a rugged, lightweight construction that enables longer service life, reduced downtime, and lower operating costs over the life of the equipment.
