Arun, Sorry for the confusion. The X310 uses a commercial grade XC7K410T with a temperature range of 0-85C. Sam On Tue, Oct 15, 2019 at 10:11 PM Arun kumar Verma wrote: > Hi Sam > > Thanks for the information. My only doubt is about the FPGA. FPGA is > industrial grade or Commercial grade ?

[USRP-users] X310 and 8bit complex sampling

2019-10-16 Thread Arun kumar Verma via USRP-users
Hi Users I am trying to achieve 50MHz BW (25MHz Each Channel)  with X310 and TwinRX using 1G Ethernet. I went through some of the forums regrading this and found that X310 does not support 8-bit IQ samples as mentioned in below link.

Hi Nate, thanks for the hint. I just double checked. The MTU size is set to 1500 on the device for sfp0. I just attached the output of `ip a` for that. The MTU is set to 1500 on the host as well. And yes, the .213 is connected to the sfp0 port. I ran 2 additional tests. I connected my host and

Hi list, since I had a few problems with our new N310s I thought it might be helpful to share my experience so far. First off, my initial error during `uhd_usrp_probe` (and also when I tried to run a GR flowgraph) is fixed. 1. I followed Robins advice to install UHD 3.14.1.1 and use the SD card

Greetings Nate, So been working through your instructions you linked and everything appears to be good on the software end. It is all cross-compiling and running on the E312. Unfortunately there appears to be a new issue. So when running the GUI for building an FGPA bit file, per the

The E310/E312 has a small-ish FPGA that does not have enough resources to accommodate the overhead associated with 14 RFNoC blocks. You have discovered empirically that you run out of space above 5 blocks. On Wed, Oct 16, 2019 at 10:06 AM Jonathan Lockhart via USRP-users <

[USRP-users] E310 GPS time source?

2019-10-16 Thread zcao--- via USRP-users
Hi, UHD lib provides a function, get_time_last_pps(), which suppose to provides the time stamp for the latest PPS right edge. I am wondering what is the source of the time information the above function uses? Specifically, we are aiming at synchronize multiple E310 devices for a TDMA system.
