RF survey meters measure electromagnetic field strength to diagnose RF signal integrity and determine the safety of sites surrounding RF radiation emitters. ATEC carries both broadband and selective RF survey equipment. A broadband field meter detects the total field strength, whereas a selective radiation meter can test both total strength and isolate signal sources to determine their individual strengths.
Broadband RF field meters pair with isotropic E-field and H-field probes that can be further divided into flat probes and shaped probes. Flat probes operate within a certain frequency range. Shaped probes are designed for testing to FCC, IEEE, ICNIRP, Canada SC-6 and other similar test standards, providing users with the percentage of the standard the environment under test achieves. Selective radiation meters use E-field and H-field antennas with single-axis or three-axis measurement, with antennas specializing in both low-frequency and high-frequency testing. Three-axis antennas are advantageous because they automatically deliver isotropic results.
Performing RF surveys is a vital practice for any business operating telecommunications, broadcasting or radar systems. Antennas generate powerful levels of RF which, if untested, may interfere with neighboring sources or endanger people. Users can simply connect a meter to a probe or antenna and start logging, with units like the NBM-550 offering features like an intelligent probe interface that recognizes the type of probe, automatic zero-point adjustments and the capacity to store up to 5,000 results.
