Agilent 8903B Audio Analyzer
The Keysight/ Agilent/ HP 8903B audio analyzer. Ideally suited for audio measurements from 20 Hz to 100 kHz. The 8903B is an easy to use low-distortion audio source , high-performance distortion analyzer, frequency counter, ac voltmeter, dc voltmeter, and SINAD meter. With microprocessor control of source and analyzer, the 8903B can perform stimulus-response measurements (such as signal-to-noise ratio and swept distortion) automatically with no additional equipment. For ease of use, most measurements on the 8903B are made with only one or two keystrokes. The 8903B automatically tunes and auto ranges for maximum accuracy and resolution. For quick identification of input signals, the analyzer counts and displays the input frequency in all ac measurement modes.
