The Agilent/Keysight 85660A is an RF section designed as a dedicated front-end for the 8566A Spectrum Analyzer, enabling detailed signal analysis across RF and microwave frequency ranges. This obsolete component interfaces with the 8566A through HP-IB connectivity, providing the RF signal path necessary for advanced measurements in demanding test environments. Though no longer manufactured, operational documentation and limited support remain available through Keysight resources.
Technical Specifications
Product Type: RF Section for Spectrum Analyzer
Compatibility: Designed exclusively for integration with the Agilent/Keysight 8566A Spectrum Analyzer
Interface: HP-IB connector for controller communication
Product Status: Obsolete — no direct replacement identified by manufacturer
– Key Features
• HP-IB interconnection enables remote control and automated measurement sequences when linked to external controllers
• Front-end RF architecture optimized for the 8566A signal chain
• Programming and operational parameters documented in the 8566A user manuals
• System-level integration requires HP-IB interconnection cable between the 85660A, 8566A, and controller
– Typical Applications
• RF component characterization and validation
• Wireless communication system analysis
• Electromagnetic interference (EMI) testing and diagnostics
• General-purpose RF signal measurement and analysis
– Compatibility & Integration
Operation requires the 8566A Spectrum Analyzer as the primary instrument. Control and measurement setup are governed by parameters documented in both the “8566A Spectrum Analyzer Operation Manual” and “8566A Spectrum Analyzer Remote Operation User’s Manual.” HP-IB interconnection is mandatory for external controller communication. Calibration and repair services may be available through Keysight Service Centers, though availability is limited for obsolete products.
