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.
– Technical Specifications
• Frequency range: Up to 20 GHz
• Sample rate: Up to 100 MSa/s
• Minimum pulse width: 4 ns
• Connector conversion: 15-pin D-sub (input) to coaxial SMB male (output)

• Trigger input: 1 channel for generator synchronization
– Key Features
• Direct coaxial interface eliminates bulky D-sub connectors and enables easier integration into test systems.
• Supports simultaneous measurement across four independent test receivers plus one reference channel.
• Four internal pulse generators deliver synchronized outputs with minimum pulse widths down to 4 ns.
• Dedicated RF pulse modulation input for direct amplitude or phase control of transmitted signals.
• Trigger input ensures deterministic timing alignment across all pulsed measurements.
– Typical Applications
• Radar system characterization and pulse modulation testing
• Pulsed antenna measurements and pattern verification
• Wireless communication burst signal analysis
• High-speed digital circuit pulsed RF validation
– Compatibility & Integration
Designed for direct integration with Keysight PNA-X series network analyzers, including the N5242A. User manuals, service documentation, and configuration guides are available. The adapter draws power from the host PNA-X instrument.
