Signals Intelligence (SIGINT)

Ever-faster growth in the types and varieties of wireless technologies poses an escalating challenge for intelligence and homeland-security agencies. Whether the mission is intercept and collect, detect and eradicate, monitor and track, or trend and analyze, our diverse technology base and deep familiarity with wireless communications ― gives you an edge that increases the probability of earlier detection, assessment and response.

Keysight solutions for signals intelligence include signal, intercept and collection systems, frequency management tools and high end test equipment for developers of signals intelligence systems.
