Hi all,
running Gnuradio 3.7.10.2 and UHD 4.0.0 rfnoc-devel latest commit (tried
earlier versions too). I've got a simple tx/rx flowgraph going on. The
simple description is:
Random input data -> Pack 1 Bit->Chunks to Symbols->Interpolating FIR
Filter->USRP Sink
USRP Source-> Polyphase Clock Syn
A quick update to this question with more info. I did some further analysis
by capturing the received I/Q data from the USRP Source block when
transmitting the BPSK that works without errors (symbols are 0.707+0.707j,
-0.707-0.707j) and also when using the BPSK that gives errors (symbols are
+1/-1)

Hi all,
as far as I'm aware, the two daughter boards on the x310 device each allow
for full duplex communication simultaneously. In other words, I should be
able to connect a string of (or a ring network too) for e.g. three x310
devices together. Assuming the answer to that is yes, are there any
s
As a follow up to this, I was successful in getting an example flowgraph
working using the UHD USRP Sink/Src blocks with 2 channels each. I've
attached the flow graph (note the blocks are disabled here) - on the
hardware I hook up A: TX/RX to A: RX2 and B: TX/RX to B: RX2 and it works
as expected.
Hi,
I'm using gnuradio 3.7.12 and rfnoc-devel commit 1908672.
I'm trying to use both daughter boards on the x310 each at full duplex
(that is, I will have 2 independent tx paths and 2 independent rx paths).
So far I have accomplished this by using the UHD: USRP Sink/Source blocks
and setting them

Hi Mike,
Make sure your MTU is set to 9000. Are you using 1GigE or 10GigE? Do you
see underruns improve when running with only 1 TX radio?

Hi all,
Looking at implementing a TDMA like system with UHD and I'm
interesting in qualifying what constraints or limitations exist w.r.t.
AD9361 based devices. From my look into the code, UHD places the
AD9361 FDD mode with both chains enabled and basically always receives
samples unless a burst
