Hello Diniz,
40 MHz (analog filter bandwidth of the daughterboard). A USRP 2 can continuously stream at 50 MS/s (complex baseband samples) using the 8-bit wire mode. That means that the maximum bandwidth that the device can cover is limited by the analog filter bandwidth of the daughterboard, which is 40 MHz. But the 8-bit wire mode reduces the dynamic range of the data, and since the USRP 2 does not have a large internal buffer, you cannot really use the 16-bit wire mode at 50 MS/s (unless you are happy with very short, discontinous snapshots of I-Q data). The maximum sustainable rate at the 16-bit wire mode is 25MS/s (=25MHz max bandwidth). (Also, do not forget that the filters - either analog or digital - are not ideal, and that may further reduce the usable bandwidth of the device in some scenarios.) Regards, Kyeong Su Shin. ________________________________ 보낸 사람: Rafael Diniz via USRP-users <usrp-users@lists.ettus.com> 대신 USRP-users <usrp-users-boun...@lists.ettus.com> 보낸 날짜: 2018년 8월 25일 토요일 오전 8:48:21 받는 사람: usrp-users@lists.ettus.com 제목: [USRP-users] Max instantaneous bandwidth on USRP2 Hi all, Which is the maximum instantaneous bandwidth I can capture from a USRP 2 with a WBX daughterboard? Thanks, Rafael Diniz
