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 P5026B presented here is a 4-port model of the P502xB family with a frequency range from 100 kHz to 32 GHz. Compared to the P5025B (up to 26.5 GHz), the P5026B offers additional scope in Ka-band - ideal for broadband duplexers and multi-port filters, crosstalk analysis, active/passive front-end modules, precise antenna matching and mixer/converter tests. Compared to the 2-port variants (P5006B-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 P5027B/P5028B (44/53 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.
- Frequency coverage depending on model: 9 kHz to 4.5/6.5/9/14/20 GHz and 100 kHz to 26.5/32/44/53 GHz.
- System dynamic range: typically up to 150 dB in the lower GHz range (depending on model/frequency) for reliable measurements even on highly attenuating DUTs.
- Maximum output power: up to +13 dBm (typical, up to 4.5 GHz); decreasing at higher frequencies - ideal for linear excitation and good SNR.

- Fine frequency resolution & accuracy: Resolution 1 Hz; frequency accuracy typ. in the ppm range.
- Level accuracy: typ. up to ±0.2 dB (up to 15 GHz) for reproducible power and gain measurements.
- Robust inputs: permissible damage level +27 dBm or ±35 V DC.
- Connectivity & references: Thunderbolt 3/4 (USB4) to host PC, 10 MHz Ref-In/Out, additional USB-A ports for peripherals.
- Multiport measurements: Connection of two base units with Y1701A interconnect cable kits.
- Compact & lightweight: Streamline form factor; 4-port design - ideal for laboratory, production and mobile applications.
- Parallel tests (multi-site): up to two independent VNA instances per PC for higher throughput.
- Expandable via software: Spectrum analysis (S97090xB), pulse RF (S97024xB/S97025xB), extended time domain analysis with TDR (S97011B).
