Testing the Audio Performance of the EUT Receive Path The performance of the EUT receiver can be tested in isolation with the set-up shown below. As a replacement for the external audio IN, it is also possible to use an internally generated tone. Use of this tone is ideal for quick tests and as it is generated internally, it does not pass through the MT8852A CODEC.
MT8850A / MT8852A Bluetooth Test Set (MT8852A only) Audio Measurements Putting the EUT into Remote Loopback It is also possible to put the EUT into remote loopback. The MT8852A will then send and receive SCO packets from the EUT. The packets will be looped back digitally in the EUT baseband and so will not introduce any distortion from the analogue circuits. As with the set-up for testing the performance of the receiver, it is also possible to use an internally generated 1 kHz tone.

Appendix D. Bit and Frame Error Rates The flow diagram below illustrates the decision processing performed by the MT8850A/MT8852A in determining bit and frame error rates.
Appendix E. Connector Care and Handling Follow the precautions listed below when handling or connecting cables. Complying with these precautions will guarantee longer component life and less equipment down time due to connector or device failure. Also, such compliance will ensure that Beware of destructive pin depth mating connectors Destructive pin depth of mating connectors is the major cause of failure in the field.
