Is it possible to get to the TX1A output the pure Signal coming from TX LO, having the Transmit/DDS' TX1 and TX2 DDS Modes set to "Disable"?

We need to know if it is possible to get a pure sine wave coming from the internal TX Local Oscillator (TX LO,
with its Frequency and Attenuation determined according to the settings in the "AD9361/AD9364 Transmit Chain" of the FMComms2/3/4 Gtk Plugin), and take it out through the TX1A output without having it influenced or changed at all by the Transmit/DDS, this is, leaving out of the way Transmit/DDS' TX1 and TX2 by setting their corresponding DDS Mode options to "Disable".
We have not been able to do this using the AD9361/AD9364 Development Tool's FMComms2/3/4 Gtk Plugin, for when we set to "Disable"  Transmit/DDS' DDS Mode of TX1 and TX2 we kill completely the signal coming out of TX1A (including TX LO). Therefore we need to know if this can actually be done, and how we could do it.

 

Your help will greatly appreciated,
Many Thanks in advance
