The Agilent/Keysight 11869A is an RF plug-in adapter that provides mechanical and electrical interfacing between HP model 8350A Sweep Oscillator mainframes and compatible RF plug-in units. It enables the mainframe’s standard operating features—including HP-IB remote programming—to extend to the connected plug-in. Power is supplied entirely through rear interface connectors from the mainframe. The adapter itself has no independent specifications; performance derives from the connected mainframe and plug-in configuration.
Technical Specifications
• Operating temperature: 0 °C to +55 °C
• Operating humidity: Up to 95% relative humidity
• Operating altitude: Up to 4572 meters (15,000 feet)
• Safety classification: Class 1 instrument per international standards
• Power source: Rear interface connectors from HP 8350A mainframe
– Key Features
• Enables HP-IB remote control of mainframe functions via the plug-in interface
• Plug-in-specific functions (output power level, RF on/off control) remain independent of mainframe control
• Passive mechanical and electrical interface—derives all operational characteristics from connected equipment
• Designed for laboratory environments with protection from temperature extremes that cause condensation
– Typical Applications
• RF signal generation and characterization using sweep oscillator systems
• Integration of 86200 series plug-in units into sweep oscillator measurement setups
• Laboratory RF testing and measurements requiring sweep capability
– Compatibility & Integration
The 11869A is engineered specifically for the HP 8350A Sweep Oscillator mainframe. Two configuration options are available:
• Option 004: Supports 86200 series Option 004 plug-ins featuring rear-panel RF OUTPUT. Includes two semi-rigid coax cable extensions and Type-N (f) output connector.
• Option 006: Designed for 86200 series plug-ins with rear-panel AUX OUT connector.
The product is listed as obsolete but remains supported through Keysight self-help resources.
