Keysight U8903B Performance Audio Analyzer

The Keysight U8903B is a configurable audio generator and analyzer for measuring the most demanding audio devices with high accuracy. It combines very low residual distortion, wide measurement bandwidth, and flexible analog and digital interfaces so one instrument covers everything from component testing to full speech and audio quality assessment.

Key Features

• Very low residual distortion: better than 110 dB for highaccuracy measurements on demanding devices
• Wide measurement bandwidth: 10 Hz to 96 kHz as standard, extendable to 1.5 MHz with the bandwidth option
• Scalable analog channels: a 2 channel base unit, expandable to 4 or 8 analog analyzer channels
• Flexible measurement setup: up to 8 analog and digital analyses at once
• Digital audio interface option: AES3/SPDIF and DSI formats for digital radio and similar applications with 8 bit to 24 bit audio
• Logic level input: supports 1.2 V to 3.3 V for testing common components and applications
• Bluetooth audio option: test Bluetooth audio devices through a Bluetooth link
• Speech and audio quality analysis: POLQA and PESQ perceptual measurements
• Automated testing: a test sequence function runs repeatable test procedures
• Flexible connections: balanced XLR and unbalanced BNC connections with selectable impedances
• Filters: selectable low pass, high pass, and weighting filters, including A weighting, CCIR 468, C message, de emphasis, and CCITT
• SCPI compatibility mode: lets you run programs written for older audio analyzers

Typical Applications

• Audio R&D and design verification
• Production line testing of audio products
• Testing of amplifiers, codecs, and converters
• Smartphone, headset and Bluetooth audio device testing
• Digital radio and broadcast equipment testing
• Speech quality and telecom audio testing

Why Choose It

The U8903B gives you lab grade audio performance in a single configurable instrument. You can start with a two channel system and add channels, digital audio, Bluetooth, and wider bandwidth as your testing needs grow while automated sequences and SCPI support make it easy to build into production and automated test systems.
