HP 8903B Audio Analyzer 20 Hz to 100 kHz. Measures distortion, SINAD, signal to noise, True RMS Volts, DC Volts, and frequency. Built-in low distortion source. HP-IB. The standard 8903B comes with 30 kHz and 80 kHz low-pass filters only. Two slots can accept any of the 6 optional filters.
HP 8903B Audio Analyzer. Measures distortion, SINAD, signal-to-noise. Measures true-rms AC volts, DC volts, frequency. Low-distortion programmable source rms, average, and quasi-peak detection
The 8903B audio analyzer provides unparalleled versatility and performance for audio measurements from 20 Hz to 100 kHz. The 8903B combines the functionality of a low-distortion audio source, high-performance distotion analyzer, frequency counter, ac voltmeter, dc voltmeter, and SINAD meter into one compact package. 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 autoranges for maximum accuracy and resolution. For quick identification of input signals, the analyzer counts and displays the input frequency in all ac measurement modes.
