radio-frequency measurement [′rād·ē·ō ¦frē·kwən·sē ′mezh·ər·mənt]

(electronics)

The precise measurement of frequencies above the audible range by any of various techniques, such as a calibrated oscillator with some means of comparison with the unknown frequency, a digital counting or scaling device which measures the total number of events occurring during a given time interval, or an electronic circuit for producing a direct current proportional to the frequency of its input signal.
