Parameter Description Range Default Notes
o 2: 8-PSK normal modulation including the training
sequence
In 3G / 4G RAT the parameter is ignored.
LTE SC-FDMA OFDM modulation (5 MHz
bandwidth), FDD, is automatically set using for <TX_
channel> an EARFCN value.
The LTE Cat.M1 SC-FDMA OFDM modulation (1.4
MHz bandwidth), FDD, is automatically set using an
EARFCN value for the <TX_channel> parameter.
<TX_time_
interval>
Time 0 ÷ 600000 1000 Time interval for TX test expressed in ms
o 0: burst sequence is continuously transmitted. In
this case the command will immediately return
the information text response. The command line
will be immediately available for any +UTEST
command. Provide AT+UTEST=1 command to
stop the burst sequence transmission, any other
+UTEST commands can be set and the current
sequence transmission is stopped.
14.4.6SARA-R4 RF test description examples
In RX mode test command examples the information text response is issued after the timeout configured
in the set command.
Command Response Description
AT+UTEST=2 +UTEST: 32,1000,-89,-88,-87
OK
The module measures the antenna RX level
at RX channel 32 band GSM 900 for 1 s
interval.
In the example -89,-88,-87 are the
antenna RF level estimation: the
numbers are just an example.
AT+UTEST=2,885,5000 +UTEST: 885,5000,-66,-65,-65
OK
The module measures the antenna RX level
at RX channel 885 band DCS 1800 for 5 s
interval.
AT+UTEST=2,10562,2000 +UTEST: 10562,2000,-60,-60,-59
OK
The module measures the antenna RX
level at RX channel 10562 band B1 for 2 s
interval on the main antenna path.
AT+UTEST=2,10562 +UTEST: 10562,1000,0,-85,-85,-85
OK
The module measures the antenna RX level
at RX channel 10562 band B1 for 1 s interval
on the main antenna path.
AT+UTEST=2,65,3000,0 +UTEST: 65,3000,0,-63,-62,-62
OK
The module measures the antenna RX level
at RX channel 65 band GSM 900 for 3 s
interval on the main antenna path.
AT+UTEST=2,4357,,1 +UTEST: 4357,1000,1,-51,-51,-51
OK
The module measures the antenna RX level
at RX channel 4357 band B5 for 1 s interval
on the diversity antenna path.
AT+UTEST=2,102174,500,0 +UTEST: 102174,500,0,-71,-70,-70
OK
The module measures the antenna RX level
at RX channel 2174 band FDD 4 for 0.5 s
interval on the primary antenna path.
AT+UTEST=2,105230,,1 +UTEST: 105230,1000,1,-72,-71,-70
OK
The module measures the antenna RX level
at RX channel 5230 band FDD 13 for 1 s
interval on the secondary antenna path.
AT+UTEST=2,109690,,0 +UTEST: 109690,1000,0,-52,-51,-50
OK
The module measures the antenna RX level
at RX channel 9690 band FDD 29 for 1 s
interval on the primary antenna path.
AT+UTEST=2,109690,,1 +UTEST: 109690,1000,1,-52,-51,-50
OK
The module measures the antenna RX level
at RX channel 9690 band FDD 29 for 1 s
interval on the secondary antenna path.
