How do you send a cat-m 6RB@0 signal？

[ychen]

I want to tested RF performance ，so i hope send cat-M 6RB@0 signal.For example, the circled part of the picture:,it's send 6RB@22 signal。please tell me AT command.

Hi!

I think the AT command %XRFTEST is what you're looking for. It performs RF testing for the nRF9160 and you can choose both RX testing and TX testing. 

Is this what you were looking for?

Best regards,

But I don't know which statement of the AT command is a 6rb-@ 0 signal, right?

Hi, the documentation lays out how to set the different parameters.

I have not seen the signal notation you're using before but a colleague suggested 6 RB is tone count and 0 is dBm. In that case for TX testing:

<param2> is TX signal power at antenna where you can select 0 dBm and <param5> is RB/Tone count where you can set 6 RB. Table 1 also shows you allowed parameter combinations for <param5>, <param6> and <param7>. 

Best regards,

Heidi
