Keysight (Agilent) E5057A SSA-X Signal Source Analyzer, 1 MHz to 44 GHz

The Keysight E5057A SSA-X Signal Source Analyzer characterizes signal sources from 1 MHz to 44 GHz with integrated phase noise analysis, spectrum monitoring, and transient measurements. Built for R&D, manufacturing, and service environments, this instrument delivers phase noise sensitivity of −171 dBc/Hz (RF = 16 GHz @ 1 MHz offset, typical) through cross-correlation methods and an ultra-low noise internal reference source.

Technical Specifications

Frequency Coverage: 1 MHz to 44 GHz Phase Noise Performance: −171 dBc/Hz sensitivity (RF = 16 GHz @ 1 MHz offset, typical); offset frequency range from 1 mHz to >1 GHz Measurement Capabilities: Absolute and residual phase noise, baseband and AM noise, transient measurements (frequency, power, phase), DC current, spectrum monitoring, VCO characterization, pulsed RF signal phase noise, and precision jitter analysis. Two-port vector network analysis and millimeter-wave measurements available with specific options.
