Agilent/Keysight P5028B

The Keysight P5028B is a compact, four-port Vector Network Analyzer from the Streamline series designed for RF and microwave component characterization from 100 kHz to 53 GHz. This faceless, portable instrument delivers advanced measurement capabilities comparable to benchtop VNAs while maintaining a small footprint suitable for space-constrained environments. Connected via Thunderbolt 3 interface, the P5028B enables high-speed data transfer to a host PC and supports a suite of measurement applications including time-domain analysis, noise figure measurement with vector correction, gain compression analysis, and spectrum analysis.
