Part Details | NOISE LEVEL METER

6625-01-149-3890 An instrument which measures the level of continuous noise present in amplifier and/or receiver circuits with reference to a fixed level of signal generated by a separate noise source. It is designed to measure noise levels over a wide band of frequencies including radio and video frequencies, and is normally calibrated in decibels relative to a specified r.m.s. voltage summation across a specified impedance, or in decibels relative to a specified noise power level. If only audio frequency range, see METER, AUDIO LEVEL.
