Classification: Internal Use Only Hi,
We have recently purchased a x310 and are busy testing it’s capabilities. We would like to use the x310 to stream out and receive wideband signals at a sample rate of 100Msps and 200Msps. I have connected 2 x 10Gbe, however when using the gnuradio UHD-USRP sink with two channels, I get Underruns or Late packets error at sample rate of 66.7Msps and above. The same error happens also with the UHD benchmark tool. However, it works with one channel, with one 10Gbe connected at a sample rate of 200Msps, with few underruns in the beginning. I have the following questions: 1. Is it possible to achieve 2 x 200Msp with dual 10GBe without using DPDK? if so what are the necessary configurations that have to be made using gnuradio? Is another image required for the x310 (other than the bit image files downloaded from ettus) in order to enable stream on both 10GBe at the same time? 2. What is the max sample rate feasible using one 10GBe. 3. How can we enable to stream out using dual 10GBe in gnuradio? 4. I tried to install DPDK also but was not successful in running it. Which version of DPDK is recommended with uhd 3.15. What are the exact procedures for setting up DPDK. 5. It is required to transmit a band of a signal (bandwidth lower than the sampling rate) using Gnu-radio and x310. However, the output from the X310 is distorted as shown in the attached file. Also the signal is extended to the full band equal to the sampling rate. This happens by using 16bit integer samples. Moreover, the signal obtained from the X310 is different when using 12 bit int wire, the output extends the full band but is not the same as the input signal. 6. Moreover, I want to use RFnoc with UHD 3.15, however I do not have vivado to compile RFnoc for this version. Are there existing images for RFnoc compatible with the latest version of UHD 3.15? We would want the RFNOC image bit file for X310 that contains Replay block. Any help would be appreciated and I am also posting this to the gnuradio mailing list.
