Example of production tests for OEM manufacturer:
1. Trigger TX GMSK burst at low Power Control Level (lower than 15) or a RX measure reporting to check:
o If ANT pin is soldered
o If ANT pin is in short circuit
o If the module was damaged during soldering process or during handling (ESD, mechanical shock…)
o If antenna matching components on application board are soldered
o If integrated antenna is correctly connected
To avoid module damage during transmitter test when good antenna termination is not
guaranteed, use a low Power Control Level (i.e. PCL lower or equal to 15). u-blox assumes no
responsibilities for module damaging caused by an inappropriate use of this feature.
2. Trigger TX GMSK burst at maximum PCL:
o To check if the power supply is correctly assembled and is able to deliver the required current
3. Trigger TX GMSK burst, TX 8PSK burst and TX WCDMA signal:
o To measure current consumption
o To check if module components were damaged during soldering process or during handling (ESD,
mechanical shock…)
4. Trigger RX measurement:
o To test receiver signal level. Assuming that there are no losses between ANT pin and input power
source, be aware that the power level estimated by the module can vary approximately within
3GPP tolerances for the average value
o To check if module was damaged during soldering process or during handling (ESD, mechanical
shock…)
5. Trigger TX GMSK, TX 8PSK burst and TX WCDMA signal and RX measurement to check:
o Overall RF performance of the device including antenna measuring TX and RX power levels
