Hi all,
I was trying this loopback trick (
https://corvid.io/2017/04/22/stupid-rfnoc-tricks-loopback/). In step 2, I
did radio_ctrl->set_rx_streamer(true, 0) in UHD. (0/Radio_0 is my RX radio,
which radio_ctrl points to.)
In step 3, a steam_cmd is issued to the RX radio. But, what streamer_args
do
Hi,
I'm new to RFNOC development. I have an X310 with an SBX on slot A, and I
want to do a loopback from antenna port RX2 to TX/RX using RFNOC blocks. I
tried connecting 0/Radio_0 ==> 0/DDC_0 ==> 0/DUC_0 ==> 0/Radio_0 by the
following commands:
rx_graph->connect(radio_ctrl->get_block_id(), ddc_ct
des for doing this?
Best regards,
Alex

Hi,
I was wondering what exactly does the value of the time_spec in rx_metadata
mean? I thought it is the timestamp of the first sample in that packet when
it is received in the hardware. But, when I tried
uhd/host/examples/latency_test and printed out the timestamps in metadata,
I observed that t
Hi,
I'm doing OFDM TX/RX on a pair of USRPs N210 with SBX. Here is my device
list:
USRP A, Antenna port: TX/RX
USRP B, Antenna port: TX/RX
USRP C, Antenna port: TX/RX
For A->C, A->B and C->B, it works fine. But, B->C, I can not decode the
OFDM symbols. The antennas are placed roughly 50cm apart.
Hello,
I'm trying to transmit one OFDM frame from one USRP to the other one using
GNURadio. The flow graph is as follows:
TX side: vector source -> stream to tagged stream -> OFDM Transmitter ->
UHD sink
RX side: UHD source -> OFDM Receiver -> null sink
OFDM parameters: fft_len=64, cp_len=16
USR
