Anritsu has introduced its test set for measuring the new generation of products using the Bluetooth Advanced Audio Distribution Profile (A2DP), headset profile, and hands-free profile.

Providing frequency coverage of 20Hz to 20kHz, the MT8855A 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 as a 5-point frequency response plus THD+N, stereo separation, and stereo phase test is typically conducted in less than 15 seconds, including inquiry and connect time.

Anritsu has developed BlueAudio software which features a measurement suite that supports all key parameters, including level, THD+N, stereo separation and stereo phase, to fully characterize audio products in production. For design verification and R&D applications, BlueAudio can display an audio FFT, frequency response curves, and THD+N against level and THD+N against frequency.
