Figure 76: Setup with spectrum analyzer and signal generator for radiated measurements
This feature allows the measurement of the transmitter and receiver power levels to check the
component assembly related to the module antenna interface and to check other device interfaces
on which the RF performance depends.
⚠ To avoid module damage during the transmitter test, a suitable antenna according to module
specifications or a 50 Ω termination must be connected to ANT pin.
⚠ To avoid module damage during receiver test the maximum power level received at ANT pin must
meet module specifications.
☞ The AT+UTEST command sets the module to emit RF power ignoring 2G/3G signaling protocol.
This emission can generate interference that can be prohibited by law in some countries. The use
of this feature is intended for testing purposes in controlled environments by a qualified user and
must not be used during the normal module operation. Follow the instructions suggested in the u-
blox documentation. u-blox assumes no responsibilities for the inappropriate use of this feature.
Example of production tests for an OEM manufacturer:
1. Trigger TX GMSK burst at low Power Control Level (lower than 15) or a RX measure reporting to
check:
o If the ANT pin is soldered
o If the ANT pin is in short circuit
o If the module was damaged during soldering process or handling (ESD, mechanical shock…)
o If the antenna matching components on the application board are soldered
o If the integrated antenna is correctly connected
⚠ To avoid module damage during the 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 damages caused by an inappropriate use of this feature.
