Hello，
I am using LimeSDR-USB and GNURadio（windows edition） to transmit signals. The model of GNURadio for LimeSDR transmit is called “LimeSuit Sink” ，just as follows：
The PA Path can be set to Band1 or Band2 .So my question is:
(1) What dose PA Path mean，and how to choose？
(2) I noticed that the there are two RF connectors for TX1 port. They are TX1_1 and TX1_2. I think if I choose Band1 then the TX1_1 is chosen to transmit signal, and if I choose Band2, then TX1_2 is chosen to transmit signal. Is that ture? Because I don’t find other options to decide which TX port（TX1_1(L) or TX1_2(H)）is transmiting.
Thanks for your attention and hoping for your reply.
