XRFTEST TX set AT command for modem firmware version v1.3.6

[Carla31zv]

Hello,

Currently i would like to test my modem on TX continuous wave mode, for LTE-M. I'm using dev kit nrf9160dk, modem firmware version v1.3.6 and nrf SDK v2.7.0.

I read this documentation about the AT command (https://docs.nordicsemi.com/bundle/ref_at_commands/page/REF/at_commands/production_test/xrftest_tx_set.html#xrftest_tx_set__table_jwj_qdb_rhb)

I would like to know if parameters 8, 9 and 10 are supported by this version v1.3.6. I ask this because i do not see the tag v1.3.x next to each parameter.

I would like to know as well if there is an offset when parameter 4 is equal to 4(CW). The same, i do not see the tag v1.3.x next to description.

Currently i'm using the following command for testing: AT%XRFTEST=1,1,1,19225,23,1,4. This is correct ? I want to generate a carrier at band 1, frequency 1922.5Mz and tx power +23dBm.

Thanks!

You can set the rest of the fields to 0 or just omit them. Both commands will do the same:

AT%XRFTEST=1,1,1,19225,23,1,4,0,0,0,0,0,0 

and

AT%XRFTEST=1,1,1,19225,23,1,4

I would like to know as well if there is an offset when parameter 4 is equal to 4(CW).

Thanks for your answer, so if i well understood, there is an offset of about 400kHz as indicated on online documentation when using modem firmware version v1.3.6.

Yes, the offset is about 400 kHz
