Multi-Spectral UV/Laser Range Stimulator
Phantom™
The Phantom is a long-range laser and ultraviolet (UV) stimulator capable of testing aircraft electro-optical sensor suites up to 5 km. Phantom can operate as an independent laser and/or UV stimulator or can be integrated with our other electro-optical and radio frequency range systems (see GTESS and PRTS). The Phantom provides both a laser threat and a synchronized temporal missile plume signature to stimulate both the aircraft’s laser and missile warning systems. Training aircrew to counter maneuver a Laser Beam Riders (LBR) threat is considered essential to survival and in-air training. The Phantom can be deployed either on a shoulder or tripod mount.

Power Limiters
Keysight's power limiters provide the best broadband input protection from excess RF power, DC transients and ESD, for a variety of RF and microwave instruments and components. For example, the input circuitry of spectrum analyzers, network analyzers, frequency counters or amplifiers can be protected from unintentional inputs up to 5 watts average power. At even greater power levels, failure mode for the limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage.
