The Keysight P9371B is a 2-port vector network analyzer delivering S-parameter measurements across 9 kHz to 6.5 GHz in a portable, faceless form factor. Controlled via external PC through Thunderbolt 3, this instrument combines benchtop VNA capability with reduced physical footprint and sub-2 kg weight. It operates with 1 Hz frequency resolution and 8 dBm typical output power, employing measurement science and GUI architecture shared with higher-end Keysight VNA platforms to ensure consistency across instrument families.
