The Keysight P9373B is a portable two-port vector network analyzer operating from 9 kHz to 14 GHz with 3.5 mm female connectors. Part of the Streamline Series, it delivers measurement performance comparable to higher-end PNA and ENA platforms in a compact form factor under 2 kg. The instrument connects to an external Windows 10 PC via Thunderbolt 3, providing full VNA capabilities through software control with the same GUI and SCPI command set as Keysight’s benchtop and modular systems.
