Bluetooth test set

Anritsu has introduced the MT8855A, claimed to be the world’s first integrated test set capable of measuring the new generation of products using Bluetooth advanced audio distribution profile (A2DP), headset profile and hands-free profile, providing frequency coverage of 20 Hz to 20 kHz.

It is a suitable instrument for both design verification and manufacturing test of Bluetooth audio products, including headsets, mobile phones, digital music players, integrated and after-market car kits and desktop speakers. It establishes a standard Bluetooth link with a device under test (DUT) then performs all key measurements, including level, frequency response and total harmonic distortion and noise (THD+N), via its internal audio generators and analysers.

Measurements are conducted quickly, as a 5-point frequency response plus THD+N, stereo separation, and stereo phase test is typically conducted in less than 15 s, including enquiry and connect time.

The company has developed BlueAudio software for use with the MT8855A. Easily installed on a PC connected to the test set via USB, BlueAudio is used for instrument set-up and displays all results in a Windows-style graphical interface.

For high-volume production applications, BlueAudio includes an Auto Test mode that allows users to define and run a sequence of tests automatically.
