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.

FREQUENCY DISPLAY UNIT
TYPE NFD-1
The National RF Type NFD-1 Frequency Display Unit was designed for use with vintage and classic communications equipment, to display the received or transmitted radio frequency. The unit incorporates an internal processor that allows the intermediate frequency (IF) to be counted out by the frequency counter. The resultant display is the actual frequency that the equipment is receiving or operating at.

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.
