Hi,
The USRP sample rate and bandwidth are two different parameters in gnuradio so
if I want 20 MHz bandwidth and 100 MSps sample rate then will setting bandwidth
= 20 MHz and sample rate = 100 MHz serve my purpose? Normally sample rate (100
MHz in this case) is the bandwidth unless filter is
Hey Rob,
Since you are definitely dropping packets, I think trying DPDK is a good
next step.

Hello Wade,
Thank you for your reply.
I was going to purchase an E320 only because of the ability to use the
Replay block. Now I can do it without worrying.

Hi Jonathon,
I had not tried the "netstat -s" but after your suggestion I did and the
"receive buffer errors" does increase after running my application. I had
previously increased the ring buffer size to the max 4096.

Hi,
I have a custom rfnoc block that I am trying to test with the graph "host
=> myblock => host". "myblock" is supposed to output packets of a given
size (256) and I am trying to verify that it is doing so. However, in my
simple application to test this graph, I get the following behavior:
Your description is insufficient in detail for anyone to give you any advice at
all.

It’s RX2 input, so I’m not sure what you expect to see on your spectrum
analyzer.
You haven’t said exactly how and what you’re transmitting—what tools and
applications, nor
Hi Ofer,
The Replay block should work fine with E320. It was reverted because the
DMA FIFO was needed in the default image. You can customize and build your
own FPGA images if you need something custom.
Thanks,

Hi Cedric,
"Fatal: The connected block has an incompatible backend interface".
Try adding a short delay, such as #1 or @posedge( at the start of the
testbench to get past this.

Hello,
I collected spectrum analyzer RF input to Rx2 of the USRP, I was able to
obtain the Tx power and Bandwidth of Tx signal. At the Rx end, I also
connected the antenna to the Rx1/Tx1, and Rx2 to the RF input of the
spectrum analyzer, but Spectrum analyzer was not picking the received
signal.
