LTE-M AT command XRFTEST RX power

[Carla31zv]

Hello,

I'm using nRF9160 and modem firmware version 1.3.6.

I'm using %XRFTEST command to measure RX power received by modem. Command documentation can be found here: https://docs.nordicsemi.com/bundle/ref_at_commands/page/REF/at_commands/production_test/xrftest_rx_set.html

I would like to know what does param2 mean? At documentation it indicates that it is RX signal power at the SiP antenna port, but this is not clear.

Could you give me more information about this parameter ? For RF tests, should I set this parameter to its highest level of −25 dBm or to its lowest level of −127 dBm ? 

Thanks in advance!

Hi,

 The signal level set with param2 is used in case you need to measure the RSSI of a known signal, to set the AGC level.
