Agilent/Keysight 85670A

The Agilent/Keysight 85670A is a display section engineered as the visual interface for the 8566B Spectrum Analyzer. It provides high-resolution presentation of frequency and amplitude data from the connected RF section, enabling rapid interpretation of complex signal characteristics across the analyzer’s operating range.

– Technical Specifications

• Display Function: High-resolution frequency and amplitude display for the 8566B RF section
• System Frequency Range: 100 Hz to 22 GHz (extendable to 325 GHz with external mixers)
• Tuning Architecture: Synthesized local oscillator for precise frequency control
• Data Storage: 16 Kbytes user RAM for trace storage, instrument states, and downloadable programs
• Control System: Internal microcomputer for automated operation and feature management

– Key Features

• Modular design integrates with the 85660B RF Section of the 8566B analyzer
• Direct connection via interconnection cables to the RF section
• Microcomputer-controlled interface for streamlined operation
• On-board RAM enables trace capture and instrument configuration storage

– Typical Applications

• Frequency and amplitude characterization from 100 Hz to 22 GHz
• Extended-range measurements to 325 GHz with external mixer configuration
• Real-time signal monitoring and analysis
• Data capture and automated measurement sequences

– Compatibility & Integration

The 85670A functions as the dedicated display component within the modular 8566B architecture. The complete 8566B system comprises the 85670A Display Section and 85660B RF Section operating as an integrated pair. Interconnection requires specific cables linking the display module to the RF section. This modular configuration allows engineers to leverage the full 100 Hz to 22 GHz capability of the 8566B with optional mixer-based extension to 325 GHz.
