Agilent Technologies has introduced the U8903A audio analyser, a single-unit solution that helps users quantify characteristics that affect sound quality in audio devices. The Agilent U8903A is also the next-generation replacement for the widely used 8903B audio analyzer.
The scalable, two-channel audio analyser includes versatile measurement functions, diverse test signals, powerful analysis capabilities and industry-standard connectors (balanced and unbalanced). At DC and from 10 Hz to 100 kHz, it assists engineers and technicians in measuring audio performance in applications such as wireless audio, analog components and ICs and consumer audio. The instrument will be upgradeable to eight input channels in the near future.
The U8903A audio analyser offers wider frequency coverage, expanded performance and greater functionality. The analyser also includes a graphical user interface (5.7-inch color display) and one-button selection of major operating modes. An application note describes compatible equivalent commands and provides sample test programs comparing the old R2D2 codes with new U8903A SCPI commands.
"For nearly two decades, the 8903B provided unparalleled versatility and performance in audio applications. Today, the U8903A builds on that legacy," said Ee Huei Sin, vice president and general manager of Agilent's Basic Instruments Division. "On the bench or in a test system, the accuracy and versatility of the U8903A will help our customers make a measurable difference in the performance of their end products."
