[USRP-users] Using multiple UHD streamers

Hi all, We are building an application using multiple X300s under Ubuntu 16.04, using UHD 3.10.3.0 The application needs to transmit data to different X300s, depending on the status of the application. So, each time we need to transmit data to a different set of X300s, we destroy and re-create a

Hi all. On our side, we have tried the Promise Sanlink3, with 10Gtk 10G-SFP-T under Windows, with "limited" success in Tx (we

[USRP-users] X300: Can we use different TX sampling rates on RF A and RF B?

Hi all, I'm trying to use 2 different sampling rates the 2 TX channels of a X300. Basically, I create 2 different tx_streamers, and call usrp->set_tx_rate() for each channel. I'm getting this error from UHD: Multiple sampling rates downstream of TX Terminator 0: RuntimeError: Node 0/DUC_0

[USRP-users] X300 FPGA: UHD 3.10.2.0 vs UHD 3.10.3.0

Hi all, We are in the process of updating our software from UHD 3.10.2.0 to UHD 3.10.3.0. We see that X300/X310 FPGA version is still v.33 in the new UHD 3.10.3.0. However, the binary files from http://files.ettus.com/binaries/images/ look different. Can you confirm that we can use the same

[USRP-users] N310 time offset between TX RF Outputs

Hi all, We are trying to send 4 synchronous signals from the 4 Tx ports of the N310. We are using UHD 3.13.1.0 RC1 under Ubuntu. Central Freq = 1575.42 GHz and 1227.6 MHz Master Clock rate = 153.6 MHz We would expect to have less than 3ns offset between all TX ports of the N310, like we do with
