EVALUATION OF THE AN/URM-152 RFI METER.
Abstract
An evaluation was made of the experimental AN/URM-152 radio-frequency-interference meter developed by the Bureau of Yards and Docks for field use, Designed to be simpler to use than laboratory-type meters. Two units were first evaluated, the prototype model and a revised model, both with a frequency range of 0.15 to 400 mc. Then an evaluation was made of an experimental tuning head designed to extend the range of the meter from 400 to 1000 mc. Measurements and observations are presented of the unit's input impedance, sensitivity, bandwidth, effective frequency range, attenuation control, tuning control, metering functions, power requirement, operational characteristics, and an assessment of how nearly the meter meets the requirements set by the contract specifications. The fundamental design of the AN/URM-152 over the 0.15-1000 mc range makes it a desirable instrument for field use, but further development would be needed for it to meet operational and reliability requirements.
