Agilent/Keysight 8514A

The Agilent/Keysight 8514A is an S-parameter test set engineered for integration with the Agilent/Keysight 8510 network analyzer system. It characterizes two-port devices and networks by measuring all four S-parameters in a single connection—eliminating the need to physically reverse components or interrupt continuous measurement during network adjustments. The test set operates across 500 MHz to 18 GHz, with extended lower-frequency capability down to 45 MHz at reduced dynamic range.

– Technical Specifications

• Frequency Range: 500 MHz to 18 GHz (primary); 45 MHz to 18 GHz with approximately 30 dB dynamic range reduction
• S-Parameter Measurement: All four S-parameters of a two-port device from a single connection
• Test Port Connectors: 7-mm precision connectors; compatible with other connector interfaces via precision adapters
• Internal Architecture: Four-channel integrated frequency converter; two 90 dB step attenuators; two DC bias networks

– Key Features

• Single-connection measurement of forward and reverse S-parameters eliminates component repositioning
• Dual 90 dB step attenuators provide fine incident power control at test ports
• Integrated bias networks enable active device characterization with DC bias applied to test port center conductors
• Four-channel frequency converter supports parallel S-parameter acquisition

– Typical Applications

• Characterization of passive components where mechanical reversal is impractical
• Real-time measurement during network tuning and optimization with full error correction
• Active device testing requiring DC bias application
• Broadband two-port device validation from 500 MHz to 18 GHz

– Compatibility & Integration

Designed exclusively for the Agilent/Keysight 8510 network analyzer system. Standard 7-mm precision connectors accept appropriate adapters for non-standard connector types.
