GRC max sample rate

Can GRC handle writing data from two channels of USRP at 100 MSPS each to a file in a RAM disk ? I am using 10G server and PCIe cable. Get Outlook for iOS

Re: GRC max sample rate

Hello Koyel: I did one channel with 200 MSPS before, so probably yes (assuming that you are not doing any other processing). Consider using sc16. Also, you can try using libuhd directly. Regards, Kyeong Su Shin 보낸 사람: Koyel Das (Vehere) 대신 Discuss-gnuradio

Hi, I am using USRP 2955. I am using the code in c++ given in github to acquire data. I don’t know data is correct or not but the green light below one antenna is glowing. However, when I run a grc flowgraph I get fpga image incompatibility error. Why this different behaviour while running

Hi Ellie, being not versed in radioastronomy, I need to guess a bit here, but: Is what you want essentially "how much power is there for any Doppler shift"? If that's the case, and you're observing some known-frequency emission (say, a Hydrogen line) would that basically amount to: 1.

Re: error in grc but c++ code running on terminal

It's not clear which code "given in github" you're referring to. There's much GNU Radio code on github. Anyway, the error you see explicitly tells you what's wrong: you're using the wrong version of UHD. This happens when you somehow installed multiple versions of UHD. Uninstall the version

Looking for a way to plot V_LSR vs intensity in GNU Radio

Hey all! Hope you're doing well and having a good summer. I apologize for cross-posting here, but I wanted to pass this question by members of both the SARA and GNU Radio communities to see what resources are out there. This summer I'm working as an intern for Berkeley SETI Research Center and

Boundary alignment (follow up)

Hi everyone, Two days ago I asked something about boundary alignment, and I have been trying many stuff in GRC to solve this. I am stuck on this for days and any help will be appreciated. Below is a description of what I wish to do. 1) My transmission and receiving chain are like

Re: error in grc but c++ code running on terminal

As said, the problem is you have two versions of UHD installed. > Uninstall the version that didn't come with GNU Radio.

Re: Boundary alignment (follow up)

Hi Lannan: I am at about the same stage as you are with packetization and am researching quite similar requirements. I spent the last few days reading and experimenting with some success. There are several blocks that can help you add length tags and headers to your data stream. Look at the

Re: Boundary alignment (follow up)

wHi Kevin, Thank you for your response! I have looked at those examples and specifically those blocks already and I have looked at the C++ API reference. But still, as you said, each block requires a lot of studying, and currently I am just trying to find an easier to prepend a known
