U8903A Quick Start Guide 1
Introduction
The U8903A is a powerful, multichannel audio measurement
system that combines both generator and analyzer.
The standard option for the U8903A audio analyzer is
Option 200. The U8903A can be further expanded with
digital audio interfaces such as the AES3, SPDIF, and Digital
Serial Interface (DSI). The digital audio interfaces are
available with the U8903A Option 113, 114, and 115. Refer
to “U8903A options” on page 4 for more information on the
available U8903A options.
The U8903A is capable of performing a wide range of audio
parameter measurements on both analog audio and digital
audio interfaces. Measurement functions can be performed
simultaneously on the analog audio and digital audio
interfaces such as analog audio + AES3/SPDIF,
analog audio + DSI, and AES3/SPDIF + DSI.
The U8903A standard features are as follows.
• The analog generator has a frequency range of 5 Hz to
80 kHz, and the digital generator has a frequency range of
2 Hz to 0.45 sampling rate
• The DSI digital generator has a sampling range of
6.75 kHz to 400 kHz, and the AES3/SPDIF digital
generator has a sampling range of 28 kHz to 192 kHz
• The analog analyzer has a frequency measurement range
of 10 Hz to 100 kHz and the digital analyzer has a
frequency measurement range of 5 Hz to 0.45
sampling rate
• Frequency domain and time domain graph display of the
signal
• Sweep capability
• GPIB, LAN, and USB remote interfaces
• Refer to the U8903A Audio Analyzer User’s Guide for more information.
