Test Mode Support

The BCM20705 fully supports Bluetooth Test Mode.

In addition to the standard Bluetooth Test mode, the device supports enhanced testing features to simplify RF

debugging and qualification and type approval testing.

These test features include:

• Fixed frequency carrier wave (unmodulated) transmission

– Simplifies some type approval measurements (Japan)

– Aids in transmitter performance analysis

• Fixed frequency constant receiver mode

– Directs receiver output to I/O pin

– Allows for direct BER measurements using standard RF test equipment

– Facilitates spurious emissions testing for receive mode

• Fixed frequency constant bit stream transmission

– Unmodulated, 8-bit fixed pattern, PRBS-9, or PRBS-15

– Enables modulated signal measurements with standard RF test equipment

• Packetized connectionless transmitter test

– Hopping or fixed frequency

– Multiple packet types supported

– Multiple data patterns supported

• Packetized connectionless receiver test

– Fixed frequency

– Multiple packet types supported

– Multiple data patterns supported
