Agilent's Audio Analyzer Quantifies Performance of Audio Components, Products

September 15, 2009

Agilent Technologies Inc. introduced a single-unit solution -- the U8903A audio analyzer -- 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 legacy 8903B audio analyzer.

The scalable, two-channel U8903A 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 helps engineers and technicians measure audio performance in applications such as wireless audio, analog components and ICs, and consumer audio. In the near future, the instrument will be upgradeable to eight input channels.

Compared to the 8903B, the U8903A offers wider frequency coverage, expanded performance and greater functionality. The new model also includes a graphical user interface (5.7-inch color display) and one-button selection of major operating modes. For automated applications, 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.”

For a limited time, Agilent is offering a 20-percent discount on the purchase of a U8903A when the customer trades in a legacy HP 8903B. This makes it possible to purchase a two-channel analyzer for the price of today’s typical single-channel units.
