9、ence.1.1 Station 1 Module Download- Measure current consumption at 3.3V- Download and verify the software (include application and test mode, or test mode only)1.2 Station 2 Module functional test (Freq trim, PIO, AIO, voltage and current)Check current consumption- Feed a 3.3V supply to the 3.3V inp
10、ut. Measure the 3.3V input current and measure the voltage at 1.8V output from the module. Save the current and voltage to log fileFrequency 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
11、 0x01F6 (e.g. 0x0026), then reset DUT and verify. Save the value in log fileCheck 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 th
12、e AIO(O-I) pins at l.5V(dont I.75V), read the level form AlO and verify. Save the readings to log fileCheck Audio path- Set DUT into PCM Loopback mode. Feed 1 kHz, 5mVrms to mic input and measure, the speaker output level. Save the speaker level to log file1.3 Station 3 Module RF Test (Conducted tes
