Anritsu MT8855A Overview

The MT8855A is the world's first test set designed specifically to perform high-quality audio measurements on products using the Bluetooth Advanced Audio Distribution Profile (A2DP), the Headset profile, or the Hands-Free profile.

The MT8855A is the ideal instrument for both design validation and manufacturing test. Typical Bluetooth products that can be tested with the MT8855A include stereo and mono headsets, mobile phones, digital music players, integrated and accessory car kits, and desktop speakers. Accessory microphones and speakers connect directly to the MT8855A’s audio inputs and outputs to enable the development of a complete test system. Module testing is also facilitated using direct connection to the RF and audio connectors.

After establishing a Bluetooth connection with the DUT, the MT8855A's integrated audio generators and analyzers are used to perform measurements including level, frequency response, and THD+N.

BlueAudio software, supplied with each MT8855A, is installed on a PC that connects to the MT8855A using a standard USB cable. BlueAudio serves as the MT8855A's front panel and is used to configure the instrument and display graphical and numeric measurement results. For R&D applications the Manual Test mode provides full graphical results, whilst an Auto Test mode is available for rapid and repetitive production testing with user configurable test plans, results archiving and report generation.

The MT8855A Bluetooth Audio Test Set is dedicated to audio measurements and compliments the MT8852B Bluetooth Test Set that performs radio layer measurements on Bluetooth modules and devices.
