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 P5028B presented here is the 4-port top model of the P502xB family with a frequency range from 100 kHz to 53 GHz. Compared to the P5027B (up to 44 GHz), the P5028B offers additional headroom above 50 GHz - ideal for broadband duplexers and multi-port filters, crosstalk analysis, active/passive front-end modules, precise antenna matching as well as mixer/converter tests and 5G FR2 pre-development. 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. Those who can manage with fewer ports will find alternatives in the 2-port variants P5005B-P5008B (up to 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 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.
- Very low trace noise: Magnitude typ. 0.0005 dB rms (with suitable IF bandwidth) for high-precision results.
- 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).
