The Keysight (Agilent) 360D is a low-pass filter engineered for RF and microwave signal conditioning. It attenuates signals above 4.1 GHz while preserving minimal loss in the passband, making it suitable for noise reduction and harmonic elimination in demanding measurement applications.
Technical Specifications
• Model: Keysight 360D
• Product Type: Low Pass Filter
• Cutoff Frequency: 4.1 GHz (4100 MHz)
• Connector Type: N-Type (input and output)
• Attenuation Characteristic: Designed to attenuate signals above 4.1 GHz cutoff
– Key Features
• N-Type connectors for standard RF integration
• Sharp attenuation above cutoff frequency for effective harmonic suppression
• Minimal passband insertion loss below 4.1 GHz
• Passive design with no power requirements
– Typical Applications
• Harmonic elimination in slotted-line measurements
• Filter characteristic verification and validation
• Receiver response determination and characterization
• Preselector operation with spectrum analyzers, including HP 851A/8551A compatibility
• General RF signal conditioning in measurement systems
– Compatibility & Integration
The 360D integrates directly into RF test benches and receiver chains via standard N-Type connectors. It functions effectively as a front-end preselector when paired with broadband spectrum analyzers, protecting sensitive measurement equipment from out-of-band interference and harmonics. The filter’s 4.1 GHz cutoff makes it suitable for L-band and lower microwave frequency applications.
