Practical VLF/LF Radio Test System

摘要

A practical VLF/LF radio test system designated as the AN/URM-212, Test Set, Radio is a recent development of the Naval Ocean Systems Center working in conjunction with industry. The mission of the AN/URM-212 is to verify the operational readiness of VLF/LF receive communication systems installed in submarines. Navy aircraft, and tenders from antenna to printer. The AN/URM-212 tests processor-controlled VLF/LF receive components (e.g., VERDIN), in a quantitative manner and tests non-processor controlled VLF/LF receive components (e.g., receivers, antennas and associated couplers) in a qualitative manner. The AN/URM-212 is used to test all receive components of the VLF/LF communications system by measuring small performance degradations not discovered by automated performance monitoring, self test or other preventive maintenance procedures.
