The Keysight M9818AS is a PXIe Vector Component Analyzer receiver module designed for multiport network analysis and modulated signal measurements across 100 kHz to 53 GHz. It functions as an independent two-port network analyzer within a scalable multiport architecture, enabling simultaneous characterization of complex devices such as T/R modules and beamformer ICs. Each M9818A receiver module pairs with the M9808A PXI VNA to deliver continuous-wave and modulated signal measurements with full error correction across fully synchronous ports. The modular design supports up to 16 modules per chassis, allowing measurement throughput to scale with test complexity without redundant hardware investment.
