AD9375: ARM control of enabled signal chains

Hello,

I am trying to change which Tx chains are enabled after device initialisation using ARM control mode. I am on a custom board which does not have the TX1_ENABLE or TX_2ENABLE

Is it possible to initialise the device with both TX1 and TX2 enabled and then, sometime later, disable TX2 using ARM control mode without reinitialising the device?

I think this comment answers my question (by implying it is not possible):

https://ez.analog.com/wide-band-rf-transceivers/tes-gui-and-api-software-ad9371-ad9375/f/q-a/117747/how-to-power-down-tx-output-frequency-on-ad9375-transciever/350712#350712

but I would just like explicit confirmation.

Thanks.

    No, it is not possible to do that. When you enable or disable the TX path using the API, you have to go through the full init sequence before going to radioon so that the changes take effect. You can call  API  init_txsettings after radiooff and then use MYKONOS_initialize API and then go to radio on.
