We have a FM-Comms2 and a ZC706 eval board. On the GUI for the ZC706 board there is a Tx freq input on the GUI that sets Tx1 output. How do I set Tx2 output? My understanding is the two Tx paths are independent. Don't know how to program Tx2
I think this file is related to an example here:

Well - there are two independent TX and RX paths - however both TX share the same LO frequency.
Thus there is only one control. Same applies for RX.
If you look at the data portion - you see two independent DDS data generators for test purposes.
If you like to understand the TX data format for the two channels - take a look here:
Thanks for the clarification. I guess “independent” means different things to different peopleJ
Can Tx2/Rx2 be power down to lower DC power draw? If so, is there a command on the GUI to do so?
Take a look here:
In the fmcomms2 devicetree:
uncomment or remove following line:
Thanks for the reply. I have another question. On the Tx GUI, there is a DAC Buffer Output file that can be loaded from the GUI called "qpskwithfilt_30.72MHz.txt. I assume the sampling clk should be set to 30.72 MHz. What is the data/symbol rate for this waveform?
