How is an Audio Frequency measurement made?
Audio Frequency measures the frequency of the signal applied to the front-panel AUDIO IN connectors, and is one of the Analog Audio measurements. Audio Frequency can be measured for signals in the frequency range of 100 Hz to 15 kHz, at levels from 7.1 mV peak to 20 V peak, and with a signal-to-noise ratio of 30 dB or greater.
The analog audio frequency measurement is made after any filtering and processing are applied for the audio measurements.
