Re: [USRP-users] Configuring FIR filters for b210

Hi Victor, the baseband filters are indeed real and thus symmetric in spectrum. Best regards, Marcus On Fri, 2018-04-20 at 11:47 +0300, Victor Petrescu via USRP-users wrote: > Hi all. > > I have a b210 device on which i want to make a transceiver. I managed > to replicate 15Mhz bandwidth, but no

Re: [USRP-users] how to know the number of losted samples when overflow occurs ?

Hi Matis, the time stamp of the first buffer after a disruption should indeed be accurate, and describe the time at the first sample in that packet. So, I'd say that, yes, you can use that to know how much you've lost. Thus, let me ask you why you came to the conclusion that it is false? Best reg

Re: [USRP-users] Race Condition Issue?

When transferring code, we did a clean build, the version of boost used was the default package. I also rebooted/ran ldconfig and tried to build multiple times in case it was some weird library issue. We did get around this issue by skipping ahead to Ubuntu 18.04...and now our code runs again.

Re: [USRP-users] Race Condition Issue?

Hi, this is really far-fetched, but I remember getting into trouble with Boost.asio when I was messing around with a different libc. Did you perhaps update Boost or your libc without relinking boost against the libc your system uses? Best regards, Marcus On Tue, 2018-05-22 at 08:17 -0600, cbeck

Re: [USRP-users] API C,USRP X300

Dear Joseph, sorry for missing your email! Now, this is a bit of a broad question: To make the C examples do what you want, you'd write appropriate C code. Now, I feel like you're really asking us how to get started with writing C code, but that might be an indication that you probably shouldn't b

Thank you, Robin. We​'ll proceed to buy the Kit then. We'll keep in mind the sidenote, as we'll probably need to buy a couple extra Xilinx USB platforms :). Regards, Brais. ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/m

Re: [USRP-users] E300 JTAG Accesory kit compatibility

Hi Brais. We have not confirmed, but the older version of the Xilinx Platform USB cable should work. The NI/Digilent USB programming cable for Xilinx FPGAs definitely works. The E310 JTAG Interface cable accessory kit for the E310 is simply a passthrough adapter for the somewhat odd Xilinx JTAG

I'm not an FPGA expert by a long shot so I'm afraid I can't point at anything specific. The DRAM FIFO may offer some inspiration or the SRAM FIFOs. How and where you need to access the data will influence what the best solution is. Can you say anything more about your application? That would likely
