The Keysight P50xxB series combines precise vector network analysis with a compact form factor for PC-connected operation via Thunderbolt. It is suitable for research, development and production - from the characterization of passive components, connectors, cables and filters to amplifiers and mixers/frequency converters. Optional software functions (e.g. spectrum analysis, pulse RF, TDR) turn the VNA into a versatile RF measurement platform.
The VNA Keysight P5025B presented here is a 4-port model of the P502xB family with a frequency range from 100 kHz to 26.5 GHz. Compared to the 6-port devices (P5020B-P5024B up to 20 GHz), the P5025B combines higher maximum frequency with true multi-port functionality - ideal for wideband duplexers and multi-port filters, crosstalk analysis, active and passive front-end modules, antenna matching and mixer/converter tests. Compared to the 2-port variants (P5005B-P5008B), the 4-port design enables mixed-mode measurements (e.g. Sdd, Scc, Sdc, Scd) without an external switching matrix and significantly reduces the need for reconnection and recalibration. Within the 4-port series, the maximum frequency scales further via P5026B/P5027B/P5028B (32/44/53 GHz).
