Keysight (Agilent) E5502A Phase Noise Measurement Solution, 50 kHz to 6.0 GHz

The Keysight (Agilent) E5502A Phase Noise Measurement Solution characterizes signal sources and components across 50 kHz to 6.0 GHz with absolute and residual phase noise measurement capability. Built to minimize production ATE test times, the system delivers sensitivity and measurement speed—achieving test times under 3 seconds for 1 kHz to 100 kHz offsets and under 30 seconds for 10 Hz to 1 MHz offsets. The E5502A measures AM noise directly and supports multiple measurement techniques including phase detector, PLL/reference source, heterodyne discriminator, and frequency-discriminator methods.
