Hi all, I'm trying to synchronize 2 USRP N210 devices using the OctoClock-G CDA-2990 as external 10MHz reference and PPS sources. It is said that I need to set up two configurations: usrp->set_clock_source("external"); usrp->set_time_source("external"); Which file in which path should I modify

[USRP-users] AGC in USRP

2019-06-21 Thread Jiang, Fengyang via USRP-users
Hi, I'm using USRP to transmit and receive some signals. Can I use correlation to compare the strength of received signals across different experiments? Each time I will increase the distance between the transmitter and the receiver by a little, and is there an AGC or other modules which will a

2019-06-07 Thread Jiang, Fengyang via USRP-users
Hi, I'm transmitting a signal and receiving it using USRPs and want to estimate the frequency offset, but I'm getting something confusing. I'm using 2.45GHz for the transmitting, and the sampling rate is 1MHz. The signal consists of 5 repeated preambles, and each of them has 100 data points (i

Hi Michael, I've been trying different ways on that, and after resetting both two USRPs, they began to work. I've been using them for several days but only configured them once at the very beginning, maybe something went wrong with the system.. now they work at the ~5GHz range. I apologize for

[USRP-users] A problem on transmitting data using 5GHz

2019-05-30 Thread Jiang, Fengyang via USRP-users
Hi All, I'm using two usrps to transmit a preamble from one to the other. When I use 2.437GHz, 2.45GHz and 2.5GHz, it works, but if I use 5GHz, 5.3GHz, 5.8GHz, I will get nothing at the receiver side. What could be the problem? Devices being used: USRP N210. https://www.ettus.com/all-products/U
