The Keysight N1966A Pulse I/O Adapter is a precision interface accessory that expands the pulsed measurement capabilities of PNA-X series network analyzers. It converts the rear-panel 15-pin D-sub pulse I/O connector to coaxial SMB male connectors, enabling direct access to receiver IF gates, pulse generator outputs, RF modulation drives, and trigger signals. The adapter supports one reference and four test receiver IF gate inputs, outputs from four internal pulse generators, RF signal pulse modulation control, and trigger synchronization for complex pulsed RF test applications.
