The Agilent/Keysight 8414A is a polar display unit designed to extend the measurement capabilities of HP 8410 series network analyzers. It provides simultaneous visualization of magnitude and phase data, enabling comprehensive characterization of complex small-signal scattering parameters without the limitations of rectilinear displays.
Technical Specifications
• Display Type: Polar coordinate display for magnitude and phase visualization
• Dynamic Range: Accurate readings from approximately 40 dB of loss down to receiver noise floor
• Phase Data Computation: X and Y outputs enable phase calculation with freedom from phase ambiguities near the ±180 degree point
– Key Features
• Extends measurement range beyond rectilinear display capability
• Provides detailed phase information for network characterization
• Integrates with HP 8410 series analyzer outputs (X and Y channels)
• Eliminates phase ambiguities inherent to single-channel phase measurement near ±180 degrees
– Typical Applications
• Complex impedance and admittance measurements
• Small-signal device characterization
• Network analysis requiring both magnitude and phase information simultaneously
• Scattering parameter visualization for transmission line and component testing
– Compatibility & Integration
The 8414A is designed for direct integration with HP 8410A and HP 8410B network analyzers. It functions as a display accessory, accepting X and Y outputs from the analyzer to render polar format data. The unit operates within the measurement framework of the 8410 series system, allowing seamless incorporation into complete network analysis configurations with other compatible test accessories.
