Hi Jonas,
I use the full sampling rate for the TX sweeps since most of the
instantaneous bandwidth of the UBX is used.
Transmitting at these rates over 1Gig Ethernet would not be possible, so
I generate them using an RFNoC block inside the FPGA.

Hi,
I cannot answer your question, but out of curiosity: why do you use a
RFNoC? Seems like overkill to me.
Cheers,
Jonas

*Subject:* [USRP-users] Samples do not get through RFNoC stream splitter
Dear all,
I am working on an application where I need to transmit a frequency
ramp through two UBX-160 using different carrier frequencies.
I use a split_stream RFNoC block to copy the samples of a ramp
generator like this:
[Ramp Generator] ---> [Split Stream] --> Radio 0
'-> Radio 1
However, I see no activity on the radio outputs. If I replace the
splitter with, for instance, a DigitalGain block or I remove it, data
is transmitted correctly through any of the two daughterboards.
Here is how I connect the blocks:
/ //Connect DDS sweeper to splitter
graph->connect(dds_src_ctrl->get_block_id(), splitter_id);
//Connect splitter to radios
graph->connect(splitter_id, 0, radio_ctrl_id_b, 0);
graph->connect(splitter_id, 1, radio_ctrl_id_a, 0);/
Any help would be appreciated, thanks!
