The Keysight E5503B Phase Noise Measurement Solution characterizes signal sources and components from 50 kHz to 18 GHz. Built on decades of low phase noise and RF design expertise, this instrument delivers sensitivity and measurement integrity for oscillators, synthesizers, and RF components in both production and benchtop environments.
– Technical Specifications
• Frequency Range: 50 kHz to 18 GHz
• Offset Range: 0.01 Hz to 100 MHz
– Key Features
• Direct phase noise measurement across IF, RF, and microwave frequencies
• Direct measurement of Amplitude Modulation (AM) noise
• Extended offset range eliminates need for additional baseband analysis hardware in many applications
• System architecture comprises low-noise Modulation Measurement System (MMS) baseband test set, VXI digitizer with high-speed data interface, and measurement software
• MMS baseband test set contains phase detectors, amplifiers, filters, switches, and attenuators
• VXI digitizer samples baseband noise signal and sends digitized data to software for digital signal processing
• Stepped upgrade path available from earlier Keysight 3048 Systems
• Compatible with E5500 series measurement software
– Typical Applications
• Research and Development—characterizing and optimizing signal sources for low-noise performance in new designs
• Automated Test Equipment (ATE)—streamlining production testing of oscillators and synthesizers to reduce test times
• Aerospace and Defense—ensuring frequency stability and performance of critical communication and navigation systems
• Telecommunications—evaluating signal sources for base stations and communication infrastructure
– Compatibility & Integration
The E5503B integrates with E5500 series measurement software and supports migration from legacy 3048 Systems.
