Armed Forces
Radar and transmission installations, antenna farms and their connecting leads are regarded as radiation sources.
Radar Field Measurements - Measurement Tasks
Measurement technology featuring high dynamic range is required to evaluate high pulsed power levels. True RMS performance (e.g., using thermosensors) is often preferred.
Frequency Range
1 GHz....40 GHz
Detection of Leaks - Measurement Tasks
Waveguides and rotating couplings are subject to wear and aging and should therefore be checked regularly. Defects may cause extremely high field strengths. This requires sensors that are virtually indestructible.
Frequency Range
1 GHz....40 GHz
Satellite Installations - Measurement Tasks
Very low field strengths are usually expected in areas surrounding terrestrial stations. The measurement technology and corresponding probe should feature excellent sensitivity.
Frequency Range - Military Systems
8...9 GHz, 43.5....45.5 GHz
Frequency Range - Satellite equipment
4...6 GHz, 11 ...14 GHz
Communication installations - Measurement Tasks
In the near field area, E and H fields must be measured separately. Several antennas situated close together often emit different frequencies. Especially on ships, such installations are located in the proximity of people mandating continual measurement. Shaped probes make measurement considerably easier.
Frequency Range
(150kHz) 30 MHz ... 3 GHz
Recommended Equipment
Broadband : NBM 550, NBM 520
RF Monitors : Nardalert (B8860 or C8860)
