Agilent / Keysight N5193A UXG X-Series Agile Signal Generator

The Keysight N5193A UXG X-Series Agile Signal Generator is a signal source engineered for aerospace, defense, and wireless communications testing. It delivers rapid frequency, amplitude, and phase switching across 10 MHz to 20 GHz (Option 520) or 10 MHz to 40 GHz (Option 540), enabling real-time simulation of complex radar, electronic warfare, and communication signal environments. The instrument supports phase-continuous and phase-coherent switching modes to minimize spectral splatter and maintain phase trajectory consistency during rapid transitions.
