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.

Resonance Dip Meter
NRM-2
National RF’s Resonance Dip Meter is a test instrument used to determine the resonant frequency of a tuned circuit or resonant network, such as an antenna system. In addition, the unit may function as an RF detector, or a secondary frequency source. The instrument is analogous to the older vacuum tube “grid dip meter,” once popular in every electronic laboratory or radio station. Unique to this updated version is a buffered output that may drive a digital frequency counter for exact measurement of resonant frequency, or connected to an oscilloscope to be used as an RF detector and waveform/modulation monitor.

GT210PXI
GuideTech’s GT210PXI 3U form factor, meets industrial standard chassis with an expandable platform, achieving optimal test system with optimal cost. The ability to precisely resolve frequency and time yields both increased accuracy as well as reduced measurement time. For example, with the GT210PXI-1 you can determine any frequency to 0.01 part per million (eight digits) in just 1 mS, and resolve each time measurement to 8pS. Couple that with 2300 measurements per second, one of the fastest rates available and you can acquire more data in a single second than a typical GPIB counter can in one minute! Faster measurements and higher resolution, along with built-in statistics functions give you a more thorough analysis of your signal. Standard deviation, peak to peak jitter, or a graph of the measurements are available at the push of a button.
