The two RF receive channel in the same USRP is synchronized or not? How to synchronized?

[evelyn111]

I have two USRP 2954R devices—one for the transmitter and the other for the receiver.

I use RF0 for transmit. Use RF0 and RF1 (two channels) to receive.

Is RF0 and RF1 in the same device is automatically synchronized or not?

If not, how can I synchronize the two channels in one device?

How can I synchronize the transmitter and the receiver?

Thanks a lot.

You can try to use timed commands if you are working with the C++/Python api. You can utilize a set start time for both TX and RX.

Considering the channels, a TX/RX or TRX label indicates that the port is capable of half duplex communications. It can receive and transmit, but not at the same time.
