description:
The Keysight 8903B audio analyzer provides excellent general performance for audio measurements from 20Hz to 100kHz. The 8903B incorporates the functions of a low-distortion audio source, high-performance distortion analyzer, frequency counter, AC voltmeter, DC voltmeter, and SINAD meter into one instrument. By controlling the microprocessor of the source and analyzer, the 8903B can automatically perform excitation-response measurements (such as signal-to-noise ratio and scan distortion) without the need for other equipment. In terms of ease of use, most 8903B measurements only need to press 1 or 2 buttons. 8903B's auto-tuning and auto-ranging can guarantee the highest accuracy and resolution. To quickly confirm the input signal, the analyzer records and displays the input frequency in all AC measurement modes.
