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 and 8PSK burst and WCDMA signal:
o
To measure current consumption
o
To check if module components was 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 or
ANT_DIV
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 and 8PSK burst and WCDMA signal and RX measurement to check:
o
Overall RF performance of the device including antenna measuring TX and RX power levels
