Product Test Specification

Key words：Bluetooth Headset, PCBA, RF test, Acoustic

Summary：The test specification for Function, RF test, PCBA test and acoustic test Reference List：

1Test Procedure

Before start ATE, engineer should check and enter appropriate values in setting environment.

Manual Settings

●Software version number, eg “20131213”

●Upper and lower limit for each test items

●Started and stopped Bluetooth address range

●RF test probe and cable lost for calibration and compensation

Station Requirement

●In each station, ATE need to read, compare and display the software version number,

which is stored in PS Key 0x02B6. It is a 16 bits, 4 digits BCD, eg “6AA5”

●All test items should display on the screen

●Each production day have a log file for each station. Each log file includes all samples

serial no or BT address with corresponding testing data. The file is in ASCII format.

Each test item placed in one column. File name must include the station no, date and time for reference.

1.1Station 1 Module Download

-Measure current consumption at 3.3V

-Download and verify the software (include application and test mode, or test mode only)

1.2Station 2 Module functional test (Freq trim, PIO, AIO, voltage and current)

Check current consumption

-Feed a 3.3V supply to the 3.3V input. Measure the 3.3V input current and measure the voltage at 1.8V output from the module. [Save the current and voltage to log file]

Frequency trim

-Control the DUT to transmit a CW at Channel 39(2441 MHz), adjust the Crystal frequency trim value to meet the target. Write the correct value into PS key 0x01F6

(e.g. 0x0026), then reset DUT and verify. [Save the value in log file]

Check PIO and AlO

-Input the PIO(0-10) pins 0101 0101 0101, read the logic from PIO and verify.

-Repeat the above and invert the lo舒c (1010 1010 1010). read the logic from PlO and verify.[Save the result to log file]

-Input the AIO(O-I) pins at l.5V(don't >I.75V), read the level form AlO and verify.

[Save the readings to log file]

Check Audio path

-Set DUT into PCM Loopback mode. Feed 1 kHz, 5mVrms to mic input and measure, the
