The Agilent/Keysight 85554A is a spectrum analyzer plugin module that measures input signal magnitude across a frequency spectrum. It functions as an RF analysis tool for engineers characterizing signal power distribution, identifying signal components, and detecting noise and distortion in electronic systems.
Technical Specifications
• Input impedance: 50 ohms
• Connector type: Type-N female
• Signal measurement: Magnitude versus frequency
– Key Features
• Plugin architecture for integration with compatible host instruments
• 50-ohm RF input for standard test configurations
• Direct magnitude measurement across defined frequency bands
– Typical Applications
• Frequency response measurement of amplifiers
• Oscillator noise characterization
• Spectral purity assessment
• RF signal analysis within defined frequency bands
• Component-level spectrum measurements
• Signal integrity verification and troubleshooting
– Compatibility & Integration
The 85554A functions as a modular plugin requiring a compatible spectrum analyzer mainframe or oscilloscope system. Documentation references CalPod Drive Cable extensions (85554A CalPod Drive Cable Extension) and potential integration with the 85523B module, indicating use within networked or modular measurement systems. Specific host instrument compatibility depends on the mainframe model.
