These tapes contain a series of recorded sine-wave signals for general-purpose use for standardizing azimuth, equalization, and sensitivity (usually called "gain" or "level") of open-reel analog audio magnetic tape reproducers. They are not intended for testing tape reproducer speed, flutter, distortion, or track placement.
The signals on these tapes can be monitored with a voltmeter—either the program level meter in the tape reproducer or an external voltmeter. Useful auxiliary test equipment includes a loudspeaker or headphones to hear the voice announcements of frequencies and levels, an oscilloscope to observe waveforms, and a level recorder in order to provide a graph of the frequency response.
