The Keysight (Agilent) E5503A Phase Noise Measurement Solution is an integrated system for characterizing signal sources and RF components across 50 kHz to 18.0 GHz. Built on proven low phase noise and RF measurement technology, it delivers high measurement integrity and repeatability in both automated test environments and R&D settings. The E5503A measures phase noise and AM noise on one-port devices including VCOs, DROs, crystal oscillators, and synthesizers using phase detector methods with optional PLL enhancement for frequency tracking and in-band noise suppression.
