    POTOMAC AUDIO ANALYZER AA-51
    The AA-51A is a multi-purpose, precision audio analyzer that helps to automate proof-of-performance measure-ments and equipment maintenance. Unique features of the AA-51A make it the ideal instrument for engineers, and service professionals. Excellent RFI shielding enables measurements to be made within the high-level RF environments of commercial broadcast transmitter facilities.
    Total harmonic distortion measurements are made by simply setting the Mode Switch to THD and reading the meter. The AA-51A automatically accomplishes nulling and tuning to the input frequency. This enables the operator to accurately measure the harmonic distortion at various discrete frequencies and different power levels much faster than using conventional distortion analyzers.
    Intermodulation distortion measurements are performed with equal simplicity. Utilizing the SMPTE Standard intermodulation signal the AA-51A displays percent of IM. Measurements are completely automatic over a wide dynamic range.
    Accurate frequency response measurements are facilitated by a wideband voltmeter which exhibits a flat response (+ or - 0.1dB) from 20 Hz to 100 kHz. Input level range is 1 mV to 100 V full scale. The average responding meter is calibrated to the rms value of a sinewave. For Signal + Noise/Noise measurements the voltmeter bandwidth may be restricted to 20 kHz by placing the mode switch in the NOISE position.
    Incidental frequency modulation — “Wow and Flutter” — usually associated with tape decks, cart machines and turntables is measured automatically. The AA-51A measure weighted peak flutter as specified by IEEE Standard 193.
    Stereo signals and mono signals derived from a stereo source are often degraded by phase errors and differential gain variation between left and right channels of a given audio system. The AA-51A contains both phase and ratio measuring circuitry which enables the operator to evaluate these characteristics quickly and accurately throughout the complete audio spectrum, and over a wide dynamic range. Phase angle is displayed with a zero center scale indication and a full scale, switch selected sensitivity of either + or - 180 degrees. The ratio meter is also a zero center scale device with a + or - 6dB full scale deflection.
    The Phase and Ratio measurement features of the AA-51A are particularly useful for line equalization measurements, azimuth alignment of stereo tape heads, and trouble shooting of audio consoles, amplifiers, and networks.
