[USRP-users] Unable to Tx on 2 X300s with UHD 3.13.1.0 - benchmark_rate hangs

Hi all, We are facing a important issue with UHD 3.13.1.0 with the X300: We can not Tx on the 4 channels of 2 X300s, even with the benchmark_rate example. We were able to do this flawlessly with UHD 3.10.3 for a long time. Here's the command we use: ./benchmark_rate --args addr0=192.168.40.2,addr

[USRP-users] N310 TX gain: jump of +2dB

Hi all, We are measuring the output power of the N310 when streaming a CW signal (with the example tx_waveforms), with different values of "gain". The exact command we use is: ./tx_waveforms --args=addr=192.168.20.2,master_clock_rate=153.6e6 --rate=2560 --freq=157542 --ref=external --pps=

Hi all, I am assembling a few X300s with UBX-160 d/b. One of them is giving me troubles with a UBX-160 v2 d/b. The result from uhd_usrp_probe can be found below. Results from other X300s are normal. We have physically disconnected and reconnected the problematic d/b, but we still have the same res

[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 t

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 specifi
