The HP 8903B
Audio Analyzer provides unparalleled versatility and performance for audio
measurements from 20 Hz to 100 kHz. The 8903 B combines the functionality of a
low-distortion audio source, high-performance distortion analyzer, frequency
counter, AC voltmeter, DC voltmeter, and SINAD meter in one compact package.
With microprocessor control of source and analyzer, the HP 8903 B can perform
stimulusresponse measurements, such as signal-to-noise and swept distortion,
automatically with no additional equipment. For ease of use, most measurements
on the 8903 B are made with only one or two keystrokes. It tunes and autoranges
automatically for maximum accuracy and resolution. For quick identification of
input signals, the analyzer counts and displays the input frequency in all AC
measurement modes.
