The Anritsu 3670K50-1 is a 1-foot semi-rigid test port cable engineered for precision RF and microwave measurements. It interconnects Vector Network Analyzers to Devices Under Test and integrates with test fixtures such as the Anritsu 3680 Universal Test Fixture. Built to laboratory quality standards, this cable delivers low insertion loss performance and guaranteed return loss across its operating range, making it essential for return loss/VSWR, cable loss, and distance-to-fault measurements.
