The answer is yes.
You can refer to uhd/host/examples/python/replay_capture.py for more detail.
It’s the play-and-record example from Ettus, using the Replay Module.

Hello Hui could you solve this Issue? I am trying sth very similar. Since the
hints you got from wade, more precisely the two examples you were pointed at
are python and C++ my question is, can this be done using python only? Say
transmit num_x (say 500k-2mio samples) and receive num_x + margin
Hey Jorge Chen,
I see what you're saying. Still, I'm not even sure 8 ports will fit. You
could start with 5 ports, and then use a single streamer to get data out of
the replay block into the host. You can use the replay block API to specify
the memory region you want to download (or upload). So, t
Hi Martin
Thank you for your reply. I understand the N310’s default Replay block has
4 input and 4 output ports. In my setup, I connect the tx_streamers to the
Replay block’s input ports and route the output ports to the DUC blocks on
the TX side. On the RX side, I connect the DDC blocks to the Re
Jorge,
for 4x4 mode, you need 4 ports, not 8. If you configure the replay block
with 4 channels, it will create both 4 input and output ports,
respectively. What bandwidth are you trying to capture?
Also remember that if you TX and RX simultaneously, you will get crosstalk.

Hi all,
I’m working on a multi-channel, phase-coherent transceiver platform using
the N310 and RFNoC Replay block (UHD4.6). It has been tested successfully
for 4TX and 4RX individually.
However, I’m facing challenges getting 4TX and 4RX to work simultaneously.
Attempts to configure:

Q1) Yes, only one channel is required. Each channel has both send and receive
capabilities and you can use both simultaneously. However, note that sending
