The Hewlett Packard HP 8514B S-Parameter Test Set is a dual-port network analysis instrument engineered for precise S-parameter characterization of RF and microwave components from 500 MHz to 20 GHz. The coupler-based architecture measures all four S-parameters of a two-port device without physical DUT reorientation, preserving calibration integrity and enabling in-circuit adjustments. Four integrated RF-to-IF converters eliminate the need for device reconnection between measurements, making it ideal for active devices and complex circuits where manipulation must be minimized.
– Technical Specifications
• Frequency Range: 500 MHz to 20 GHz
• Port Configuration: Dual-port with coupler-based architecture; 3.5 mm male connectors with 7 mm test port connectors
• Impedance: 50 ohm nominal
