Product Overview

The Keysight U8903A (Agilent) Audio Analyzer combines the functionality of a distortion meter, SINAD meter, frequency counter, AC voltmeter, DC voltmeter and FFT analyzer with a low-distortion audio source. On the bench or in a test system, its accuracy and versatility will help you make an audible difference in your end product. The Keysight U8903A is the next-generation replacement for the widely used Agilent 8903B audio analyzer.

Whether listening to mono, stereo or surround, the human ear knows what sounds good. Measuring “how good,” however, can be a challenge. The Keysight U8903A audio analyzer helps you measure and quantify audio performance in applications such as wireless audio, analog components and ICs, and consumer audio.

Across the audio spectrum and beyond, this scalable, single-unit solution provides versatile measurement functions, diverse test signals and powerful analysis capabilities. Whatever your application, the U8903A can help you make an audible difference in device performance.

The U8903A is the next-generation replacement for the widely used 8903B audio analyzer. Application note ‘Migrating Code from the 8903B to U8903A (5990-4135EN)’ provides compatible equivalent commands, and sample test programs comparing the old R2D2 codes with new U8903A SCPI commands’.
