Keysight P9377B Vector Network Analyzer: Unlocking Precision in RF and Microwave Testing

Keysight P9377B/001 – Streamline Thunderbolt 3 Vector Network Analyzer (100 kHz to 44 GHz); Two Port

The Keysight P9377B/001 is a compact, 2-port Vector Network Analyzer (VNA) that delivers wide frequency coverage from 100 kHz to 44 GHz, leveraging Thunderbolt™ 3 connectivity for ultra-fast data transfers and real-time performance. Designed for engineers who demand high accuracy, portability, and flexibility, it enables precise S-parameter measurements in both lab and field environments.

This streamlined VNA is faceless and PC-controlled, meaning it operates entirely via an external laptop or desktop, reducing bench clutter and improving test setup efficiency.

Key Features

• Frequency Range: 100 kHz to 44 GHz

• Ports: 2-port full S-parameter test capability

• Interface: Thunderbolt 3 for high-speed data throughput
