IN response to the boom in demand for Bluetooth headsets for mobile phones, Anritsu has introduced a new option for its Bluetooth test set, the MT8852A.
This latest addition facilitates the testing of fully assembled Bluetooth headsets and is the first time they can be tested through the application layer protocol stack.
The result is that comprehensive testing of a headset is possible using just a single instrument.
Developed in partnership with Spanish company Cetecom, this option enables the MT8852A to simulate a mobile phone by running the Audio Gateway profile.
It allows users to perform, Connection, Authentication and Pairing, procedures that are required by the higher layer protocol.
Audio signals are then routed to the headset speaker from the headset microphone, which in turn facilitates measurements of the headset frequency response and distortion.
Anritsu's ‘Headset Profile Emulation’ option also provides microphone and speaker gain controls for full implementation of the Audio Gateway profile.
The software can also display a full listing of all the high layer messages that are exchanged between the tester and the headset, which will assist in debugging new protocol stacks.
