Agilent / Keysight 8514A S-parameter test set 500MHz to 18GHz

The Agilent/Keysight 8514A is an S-parameter test set engineered for two-port microwave device characterization across 500 MHz to 18 GHz. It integrates with Agilent/Keysight 8510 series network analyzers to deliver complete S-parameter measurement (S11, S12, S21, S22) without requiring device repositioning. A single connection captures all four parameters, enabling full two-port error correction and accurate characterization of devices integrated into larger systems or sensitive to handling.

– Technical Specifications

• Frequency range: 500 MHz to 18 GHz
• Measurement capability: All four S-parameters (S11, S12, S21, S22) for two-port devices
• Error correction: Full two-port error correction
• Attenuation: Two 90 dB step attenuators for incident power control at test ports
• Bias networks: Two networks for DC bias application to test port center conductors
• Internal architecture: Integrated four-channel frequency converter

– Key Features

• Single-connection measurement of forward and reverse S-parameters eliminates physical device reorientation
• Precision 7-mm connectors on test ports; adapter-compatible for alternative interfaces
• Dual 90 dB step attenuators enable precise signal level control
• Dual bias networks support active device testing with external DC bias
• Suitable for in-situ adjustments and devices difficult to reverse

– Typical Applications

The 8514A addresses measurement scenarios where physically reversing the DUT is impractical or undesirable—including integrated devices, handling-sensitive components, and systems requiring continuous measurement during adjustment cycles.

– Compatibility & Integration

Designed for operation with Agilent/Keysight 8510 series network analyzers. Precision 7-mm connectors accept standard adapters for non-native connector interfaces.
