[USRP-users] Changing phase with TX->RX loopback

2018-07-16 Thread Andreas Leuenberger via USRP-users
Hello all, I am using a USRP X310 with a UBX-160 daughterboard. The transmit signal on port TX/RX is attenuated and looped back to the receiver on port RX2. Every millisecond I am sending a short rectangular pulse (about 10 us long) using the 'time_spec' attribute of the transmit meta-data ('st

[USRP-users] Setting N310 TX and RX bandwidth

I am unable to set either RX or TX bandwidth on N310. When attempting to set, I get the following warning: Setting TX Bandwidth: 40.00 MHz... [WARNING] [0/Radio_0] set_tx_bandwidth take no effect on AD9371. Default analog bandwidth is 100MHz Actual TX Bandwidth: 0.00 MHz... and Set

Hi Marcus, Thanks for your answer. Perhaps this is not my issue then. I am having issue with sending and receiving a simple sine wave using N310. In the simplest case, I can take X310 run txrx_loopback_to_file with the arguments below, plot reals and imaginaries of the stored files and I can

Hello there, So i will have an ethernet connection between two computers, one of which is connected to my usrp host and the other is not connected to any SDR but simply has the files stored to be sent. What I need to do is the following: 1- Receive data coming from this Ethernet connection and d
