[USRP-users] error to create simple RFnoc block

2018-05-28 Thread Allouche Ishai via USRP-users
Hi all, I use rfnocnodtool in order to create new block. My block need to create square signal with different duty cycle. I try to do it with a simple counter that the output is depended on the counter value. My problem is that I don't success to read the input normally at all. I try to check t

Thanks Marcus, I got it to work just fine. Your remark is a little concerning... is there any more efficient way to send data over the internet? Furthermore, I actually don't necessarily need to pass the samples over the internet. I simply need to send the samples directly from the X310 to a wind

[USRP-users] UHD USB connection error with B200

2018-05-28 Thread Felix via USRP-users
Hi everyone, currently, I am trying to calibrate the TX power a USRP B200 device for different gain values. To realize this, I am calling the UHD function 'tx_samples_from_file' to send sine waves on different frequencies over cable to a frequency analyzer. The calibration itself works fine.

Hi Derek, Frankly, I can't install gnuradio on my windows PC. Do you know what is the max rate of data possible to send via xmlrcp / zmq / dpu socket? Which of the three options is more efficient? (BTW, is it possible to connect the X310's ethernet cable to the internet and control it remotely,

Hi Steve, > Do you know what is the max rate of data possible to send via xmlrcp > / zmq / dpu socket? Speed is mostly a function of your connection , not of the protocol, so there can't be a definite answer. I'd recommend just considering the overhead of any sensibly packaged piece of samples as

[USRP-users] Multiple Output RFNoC Block

I've got a single input, 4-output RFNoC block that I am trying to hook up to a C++ testbench, but I'm having some trouble. Referencing the unaligned output version from gr-ettus: https://github.com/EttusResearch/gr-ettus/blob/master/lib/rfnoc_block_impl.cc My graph is Radio -> DDC -> Custom Blo
