iltering works better with even decimation factors. On the 2954, the RF bandwidth is fixed at 80 MHz and the A/D rate is fixed at 100 MS/s. You can also choose decimation via DDC if you want. Rob On Wed, Jan 27, 2021 at 6:02 AM Koyel Das (Vehere) via USRP-users mailto:usrp-users@lists.ettus.com>

Hi, Is the phase difference between two receiving channels in USRP 2954 R or between any two channels of USRP 2955R stable? That is can I measure the phase difference using a power splitter and equal length cables and say that it will remain the same always or will it vary? Regards, Koyel
