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 P5021B presented here is a 4-/6-port model (depending on the option selected) of the P502xB family with a frequency range from 9 kHz to 6.5 GHz. Compared to the P5020B (up to 4.5 GHz), the P5021B offers additional scope in the sub-6 GHz range - ideal for multi-port S-parameters on duplexers, front-end modules, connectors with crosstalk analysis, MIMO antennas and differential high-speed lines. The six integrated ports enable true multi-port measurements without an external switching matrix and significantly reduce reconnection and recalibration work. Within the 6-port series, the maximum frequency scales further via P5022B/P5023B/P5024B (9/14/20 GHz).
Please note: The corresponding port option must also be booked.
Technical highlights of the P50xxB series
- Port options: 2-port (P500xB), 4-/6-port (P502xB); 2-/4-port up to 53 GHz, 6-port up to 20 GHz.
