The Keysight M9837A is a PXIe Vector Network Analyzer delivering multiport, multisite characterization across 10 MHz to 44 GHz in a scalable modular form factor. Built-in noise receivers and configurable test architecture enable single-connection measurements of modulated signals on highly integrated components. This instrument accelerates semiconductor and component testing through faster measurement speeds, flexible configuration, and reduced system costs in automated test environments.
