The Agilent/Keysight 8503B is an S-Parameter Test Set engineered to interface with network analyzers for precision calibration and accurate measurement of scattering parameters in RF and microwave environments. This discontinued instrument served as a dedicated test accessory paired with the Model 8505A Network Analyzer, enabling repeatable, traceable characterization of two-port devices across its operational bandwidth.
– Technical Specifications
• Frequency Range: 500 kHz to 1.3 GHz
• Impedance: 75 Ohms
• Power Requirements: 100, 120, 220, or 240 VAC
– Key Features
The 8503B operates as a complete S-Parameter measurement system, delivering the electrical interface and signal routing necessary for network analyzer calibration and device characterization. Its 75 Ω impedance aligns with broadcast and cable television standards. Multi-voltage AC input accommodates global laboratory environments without external step-down transformers.
– Typical Applications
The 8503B addresses measurement requirements in:
• RF and microwave device characterization
• Network analyzer calibration workflows
• Scattering parameter measurement of passive and active components
• Systems operating within the 500 kHz to 1.3 GHz band
– Compatibility & Integration
The 8503B S-Parameter Test Set integrates directly with the Model 8505A Network Analyzer. For applications requiring different frequency ranges, connector types, or impedance standards, Keysight offers alternative calibration solutions: the 85036B/E (75 Ω Type-N, DC to 3 GHz), 85031B (7 mm, DC to 6 GHz), 85053B (3.5 mm, 300 kHz to 26.5 GHz), and 85039B (Type-F, DC to 3 GHz).
This product is discontinued; documentation is available for historical reference and legacy system support.
