hi, all,

As it mentioned that, BB also send IQ data to LMS7002M.

However, probably TX is modulated BB data directly to carrier, then probably there is only one path data instead of IQ.

How can I do at this time?

1. send TX data only in SDR mode?
2. send TX Q data with all zeros?

what is the advice?

thx
