Agile signal generation for real-world threat simulation
Keysight XG9-class agile signal generators include the UXG models. They simulate complex signal environments with an arbitrary waveform generator for testing specific protocols or unique communication formats for radar, electromagnetic spectrum operations (EMSO), and antenna testing. Its rapid frequency, amplitude, and phase-switching capabilities allow for accurate emulation of multi-threat scenarios. Choose one of our popular configurations or configure one specific to your application.
Ultra-fast switching speed
Generate complex, dynamic signals in real-time with agile switching of frequency, phase, and amplitude with continuity and repeatability.
Pulse capabilities
Enhanced pulse modulation, including chirp, pulsed, and frequency modulated continuous wave (FMCW) radar signals, with varying pulse widths, frequency modulations, and timings.
Scalable, multi-emitter test
Emulate complex, crowded threat environments by scaling up the number of units to create thousands of radar threat-emitters and millions of pulses per second with unique antenna scans.
Baseband vector generator
Simulate complex electromagnetic environments across the full frequency range by adding an optional 1.6 GHz bandwidth baseband vector generator.

Frequently asked questions
An agile signal generator is an RF signal source designed for rapid frequency switching, dynamic waveform generation, and real-time adaptability in complex RF environments. Unlike traditional signal generators, which often have slower switching speeds, agile signal generators can quickly hop between frequencies and alter amplitude, phase, or modulation states, making them ideal for applications such as radar, electronic warfare (EW), 5G/6G communications, and satellite systems. These generators typically offer low phase noise, wide bandwidth, and rapid frequency agility, allowing them to accurately simulate dynamic signal conditions.
Electromagnetic Spectrum Operations (EMSO) testing assesses and verifies RF systems, electronic warfare (EW) capabilities, and spectrum management strategies to ensure their effective performance in contested and congested electromagnetic environments.
It encompasses various activities—such as signal detection, jamming, interference mitigation, and achieving spectrum dominance—to verify that military, defense, and security systems can operate reliably in the face of adversarial disruptions or crowded spectrum conditions.
EMSO testing ensures robust performance and spectrum control by simulating or analyzing real-world electromagnetic scenarios, which is vital for applications like radar, communications, and countermeasure systems.
Pulse density refers to the number of electromagnetic pulses that occur within a specific time frame or spatial area during the simulation and evaluation of systems operating in the electromagnetic spectrum. EMSO includes activities such as electronic warfare (EW), radar, communications, and spectrum management, where the goal is to control or exploit the electromagnetic environment. Pulse density is a crucial parameter in these tests because it reflects the complexity and realism of the simulated electromagnetic threat environment.
