Hi Håkon,

Thanks a lot for your reply. It works fine now. I was getting confused with the TX burst mode and continuous wave mode.

By sending the AT command "AT%XRFTEST=1,1,8,8800,23,1,4,6,0,0,0,0,0", I can see a continuous transmission on the spectrum analyzer.

Thanks and regards,

Royce

Hi,

[quote user=""]But even when I send the AT command to set it in continuous wave mode, I see on the spectrum analyzer that it is not transmitting continuously. Is there any other way to do this?[/quote]

The 10th parameter indicates if you want TX bursts or not. Try setting this to '0':

The behaviour when TX burst is enabled is shared here:

https://docs.nordicsemi.com/bundle/ref_at_commands/page/REF/at_commands/production_test/xrftest_tx_burst.html#xrftest_tx_burst

And please note that you are emitting a tone in a licensed band, and should conduct radiated measurements in a shielded environment.

Kind regards,

Håkon
