Introduction

The U8903B is a digital signal processing (DSP)-based audio measurement system with a
frequency measurement range of 10 Hz to 96 kHz or 1.5 MHz depending on the installed
option. The U8903B basic configuration has two channels of analog audio generator and
two channels of analog audio analyzer.
The standard option for the U8903B performance audio analyzer is Option STD. The
U8903B can be further expanded with additional analog analyzer channels; digital audio
interfaces like the AES3, SPDIF, and Digital Serial Interface (DSI); and Bluetooth
option with source and sink interface. Refer to "U8903B Options" on page
information on the available U8903B options.
The U8903B is capable of performing a wide range of audio parameter measurements on
the analog, digital, and Bluetooth audio interfaces. Up to four measurement functions can
be performed simultaneously on the analog audio. 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 Bluetooth audio
interface provides the U8903B with Bluetooth link capabilities with support for different
audio profiles and codecs. The U8903B also supports industrial standard instrument
connectivity such as GPIB, USB, and LAN. In addition, the U8903B is equipped with
frequency, phase, time, and FFT graph analysis, as well as sweep capability for frequency
and amplitude.
The U8903B also allows you to create test sequences. Refer to Chapter 7, "Test Sequence
Application" for more information.
