The Agilent/Keysight 8511A Frequency Converter extends network analyzer capability to 26.5 GHz, functioning as a four-channel magnitude and phase receiver when paired with the Agilent 8510C Network Analyzer. This specialized instrument converts RF signals across the 45 MHz to 26.5 GHz band into intermediate frequency (IF) signals for precision characterization of microwave components, subsystems, and antennas.
Technical Specifications
• Frequency Range: 45 MHz to 26.5 GHz
• Receiver Configuration: Four-channel magnitude and phase receiver
• RF to IF Conversion: Four separate RF to IF converters
• RF Source Tracking: Excellent
• Input Connectors: Four precision 3.5 mm connectors
– Key Features
• Four independent RF conversion channels with dedicated 3.5 mm input connectors
• Three input channels available for multiport device measurement; one channel dedicated to system phase-lock
• Four-channel receiver design enables simultaneous magnitude and phase measurement across multiple signal paths
• Excellent RF source tracking ensures accurate conversion across the extended frequency range
– Typical Applications
• Transmission measurements on RF and microwave components (with external power splitters)
• Reflection measurements using external bridges or directional couplers
• Multiport device characterization and subsystem analysis
• Antenna measurement and validation
• Advanced signal analysis and precision RF testing in R&D and production environments
– Compatibility & Integration
Designed for integration with the Agilent 8510C Network Analyzer. Compatible with recommended RF sources including the HP 8360 series; operation with alternative sources is possible within their respective frequency limits. Product is obsolete; direct support from Keysight is no longer available.
