[USRP-users] Fwd: UHD dropping samples running on Debian 9

2017-09-10 Thread Kevin McGuire via USRP-users
I am not sure but if your streaming at 10-million samples per second and each sample is 32-bit (two 16-bit components; I/Q) then your total needed bandwidth is 40 million bytes which means you need a 320-megabit network connection. You might need a gigabit network? On Fri, Sep 8, 2017 at 3:04 PM,

Hi Arthur. As the Ettus Knowledge Base points out, the DBSRX2 is a very old product and has been EOLed. The schematic is available here: http://files.ettus.com/schematics/dbsrx2/dbsrx2.pdf . The tunable filter capability is provided by the MAX2112 IC. Datasheet here: https://datasheets.maximint

[USRP-users] Setting DBSRX2 channel filter (1-60 MHz) bandwidth

2017-09-10 Thread Chu, Arthur H via USRP-users
Dear all, I am building a DBSRX2-based USRP application that requires highly-selective filtering characteristics (~1 MHz). With the UHD multi_usrp::set_rx_bandwidth function, the lowest value I can achieve is 8 MHz, as specified in https://kb.ettus.com/About_USRP_Bandwidths_and_Sampling_Rates
