Re: [USRP-users] how to write test for block with two output ports

Thank you Dario. I look on the example, and I have another question. like I mentioned my block is source block. In order to create the block I looked on the Siggen block and i saw that in the axi_wrapper we don't use the tlast signal by define the resize_output and by define packets Now, in the t

[USRP-users] tlast signal in source block

Hi all, I use the rfnocmodtools in order to create a source block. In order to understand how to do it I look on the Siggen block to. In the Siggen block the axi_wrapper do not use the tlast and define packet instead. I did the same but when I connect between my source block to another block that

Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet

I have used this SFP+ transceiver for both the X310 and N310, both with XG images. I do not remember if I tried the X310 with the HG image, but I think so. I am using 10gbe with single mode fiber - approximately 100m. Rob On Wed, Jul 25, 2018 at 1:51 AM Zhongyuan Zhao wrote: > Hi Rob, > > Than

Thanks Martin. I tried that, but it actually seems to be working when I look at the results. I saw you post earlier to someone about changing UHD's logging level. Is this something that can be done via a config file? I looked around, but all I could find was some references to c++ usage. > Ja

Used to have to compile the driver for the lime in debug mode to get underrun reporting. Though I believe they may have changed some of that recently. On Tue, Jul 24, 2018, 23:57 Marcus D. Leech via USRP-users < usrp-users@lists.ettus.com> wrote: > On 07/24/2018 11:42 PM, RizThon via USRP-users w

Hi,list I know usrp e310 have a ddr3 in PL part, now I need store some data in ddr3 so I can do some dsp algo. So how Can I read/write the ddr3 easy? How many space I can use in ddr3? Is there some example? Thanks! Best, Regards, Carry ___ USRP

[USRP-users] USRP-1 and UHD versions

Folks - Quick question - saw that 3.13 was released with lots of changes. I’m a poor old retired guy using a legacy USRP-1 (WX, LFTX/LFRX daughter boards) with GNURADIO for amateur radio. At what version should I lock-in UHD? When does USRP-1 support disappear? I’m using 3.9 at the moment. Ch

Re: [USRP-users] B210 sampling rate

I already tried smaller values, but not small enough. It seems the highest I can go is num_recv_frames=44. Anything higher gives me errors. At 40MS/s, without that parameter, I get 160 to 180 overflows over 20 seconds, while with num_recv_frames=44 I only get 20 to 30. This actually allows me to

SC12 actually gives me an error as soon as it starts streaming (with or without specifying num_recv_frames=44). Using the --continue option, I get tons of such errors: [ERROR] [STREAMER] The receive packet handler caught a value exception. ValueError: bad vrt header or packet fragment Error: Recei
