Test modes
Note: Since the AT test commands enable to emit RF power bypassing the LTE signaling protocol
the emission can cause interference. This feature is thus only intended for use in controlled test
environments and shall not be used during normal module operation following the instructions in
Nordic Semiconductor documentation.
5.2.1 RX test
RX ON command enables the RF receiver with the given parameters. It also measures antenna power
with a time domain power meter and returns the measurement result. RX OFF command disables RF
receiver.
RX ON has a total of four input parameters:
Parameter Range Description
3GPP band number 1 to 66 nRF9160 supported bands
Frequency 100 kHz raster 6000 to 22000 Corresponds to 600 to 2200 MHz
System mode 0 to 1 NB1 = 0, M1 = 1
Signal level at antenna -127 to -25 Signal generator level at antenna [dBm]
Table 2: RX ON input parameters
The response to the test is RX signal power at antenna port measured by DUT given in q8 format. q8
format results can be converted into dBm value by dividing the result by 2^8 (= 256).
