Anritsu has introduced the MT8855A, a test set capable of measuring products using the Bluetooth Advanced Audio Distribution Profile (A2DP), headset profile, and hands-free profile.

Providing frequency coverage of 20Hz to 20kHz, the MT8855A offers lower cost-of-test, reduced development time, and confidence in the quality of products shipped.

The MT8855A is an ideal 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 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 five-point frequency response plus THD+N, stereo separation, and stereo phase test is typically conducted in less than 15 seconds, including enquiry and connect time.

Anritsu has developed Blue Audio software for use with the MT8855A.

Easily installed on a PC connected to the MT8855A via USB, Blue Audio is used for instrument set-up and display of all results in a convenient Windows-style graphical interface.

For high-volume production applications, Blue Audio includes an ‘Auto Test’ mode that allows users to define and run a sequence of tests automatically as a ‘Test Plan’ for fast and accurate measurements.

Blue Audio features a measurement suite that supports all key parameters, including level, THD+N, stereo separation and stereo phase, to fully characterise audio products in production.

For design verification and research-and-development applications, Blue Audio can display an audio FFT, frequency response curves, and THD+N against level and THD+N against frequency.
