The first Audio Precision product was the System One, which combined an integrated generator and analyzer with a connected PC to fully automate test procedures and provide a much higher degree of computational power than the simple microprocessors used in other products at the time. By the mid-eighties, Tektronix ceased production of audio test equipment, and in members of the team that had developed the AA started Audio Precision. This changed in with the introduction of the Tektronix AA Distortion Analyzer, which automated the processes of setting levels, frequency tuning and nulling.Īt this same time Hewlett-Packard introduced the popular HPB, which combined a high quality signal generator and analyzer in a single unit.

The remaining signal was measured as an AC voltage, and thus allowed for the manual calculation of total noise and distortion to approximately 0. These early analyzers could only determine total harmonic distortion and noise combined, and worked by employing a steep notch filter to remove the fundamental frequency of the stimulus signal from the output of the DUT. The clever and inexpensive design of the HPA allowed testers to generate very high quality, low distortion sine waves that could be used for testing. One of the earliest reliable sources used for audio test was the first product made by Hewlett-Packard inthe HPA audio oscillator. Very often audio analyzers are optimized for one of these two cases. A design engineer will find it very useful when understanding and refining product performance, while a production engineer will wish to perform tests to rapidly confirm that units meet specifications. High quality audio analyzers must demonstrate vanishingly low levels of noise, distortion and interference in order to be deemed worthwhile, and must do so consistently and reliably to be trusted by engineers and designers.Īudio Analyzers find use in both development and production of products. As test and measurement equipment, audio analyzers are required to provide performance well beyond that of the typical devices under test DUTs. This signal may be generated or controlled by the analyzer itself or may come from another source e. In addition, many manufacturers have requirements for behavior and connectivity of audio devices that require specific tests and confirmations.Īudio analysis requires that the device under test receive a stimulus signal of known characteristics, with which the output signal response may be compared by the analyzer in order to determine differences expressed in the specific measurements. Audio quality metrics cover a wide variety of parameters, including levelgainnoiseharmonic and intermodulation distortionfrequency responserelative phase of signals, interchannel crosstalkand more.
