The Agilent/Keysight N9330B is a handheld cable and antenna tester engineered for field-based RF system validation. Operating from 25 MHz to 4 GHz, it delivers precise measurements of return loss, VSWR, cable loss, and distance-to-fault—essential parameters for maintaining wireless infrastructure integrity. Its portable, ruggedized form factor enables technicians to perform rapid diagnostics on coaxial cables and antenna assemblies without returning equipment to the bench.
