HL7648 +WMTXPOWER command on main/diversity paths

IoT Modules Legacy HL Series
1

Hello support,
For purposes of production and regulation testing, I am trying to get the +WMTXPOWER AT command to generate a burst emission on either antenna path (main and/or diversity). However, it appears to only produce an emission on the main antenna path, regardless of the +WMANTSEL setting.
Is there a procedure to get +WMTXPOWER working on a specified antenna path on the HL7648 that I have missed?
For reference - here is the ATI10 response in case it is a firmware specific issue:

OK

Thanks for any feedback,

I sorry (and feeling a bit silly), I’ve been told that I’m dealing with MIMO antenna solution - so all would appear fine with the Tx emission only working on the main path.

Correction - not dealing with a MIMO antenna solution…
