[USRP-users] MIMO Cable for USRPN200 and USRP2

2018-02-06 Thread Wahhab Albazrqaoe via USRP-users
I would like to use MIMO cable to connect (synchronize) USRPN200 and USRP2. Is it possible to do so? Is it safe to do so? I appreciate your comments. Wahhab Albazrqaoe ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailma

Hi Marcus, Thank you for the reply. I actually would like to create aliasing. And it seems that CBX-120 is one option to do so. I just wanted to make sure that CBX-120 is compatible (in terms of electronic circuits and voltages) with USRPN200. I appreciate your comments. Best, Wahhab ​///

[USRP-users] CBX CBX-120 Daughter Card (120 MHz)

2018-02-06 Thread Wahhab Albazrqaoe via USRP-users
I have a question about CBX-120 (120 MHz). Ettus.com mentions that this daughterboard can only be combined with USRP X3xx series. My question, can CBX-120 be combined with USRP N200? Is there any voltages incompatibility? My understanding is that contains a frequency down converter, like from GHz

[USRP-users] Enable aliasing using USRP

2017-12-28 Thread Wahhab Albazrqaoe via USRP-users
Dear All, I have question about how to create aliasing using USRP. Basically, I have USRP2 with SBX (with recent installations of GnuRadio and UHD). I would like to set the bandwidth of the RF front end to 50 MHz, and use 2MHz of sampling rate (ADC speed). I am using the following command: sudo ./r

Hi, I connect two USRP2 devices via a MIMO cable. USRP2 devices are connected (Gigabit Eth) to different hosts. I didn't change IP addresses for USRP2 devices. I use "rx_samples_to_file.cpp" to collect some complex samples from each USRP2 separately. On the USRP2 master device, "rx_samples_to_file

Dear All, We would like to sense (i.e. sample) 100 MHz of 2.4GHz spectrum. My idea is to connect 2 USRPs (USRPN200 and USRP2) via a MIMO cable (available at ettus.com). Then, we configure each USRP separately to monitor 50MHz of bandwidth (8bit per sample). My question: 1- is it possible to config

​​I have USRPB210 and would like to set the bandwidth of the RF front to a high value, like 56MHz or 61.44MHz (which I think the max value supported by B210). At the same time, I would like to set the sampling rate of ADC to 2MHz. I used the following cmd to do so: ./rx_sample_to_file --args master
