I recently started working with the USRP 200b mini in TX mode. I set up the input data(). When setting the tx_rate below 56, everything works fine, there is no data loss, the traffic is good (it is taken from the file), but as soon as I set the tx_rate to 56, I have an underflow(U). I started to study why this happens. The USRP is connected to a USB 3.1 port, with a connecting cable (also with a good transfer rate). In the documentation, tx_rate is supported at 56, if you set more, it resets to 56. I don't quite understand what I'm doing wrong, maybe I forgot to specify something or need to enable (disable) it somewhere, I hope for your advice. UHD 4.8.0.0, Boost ++ 1.87.0 drivers , OC Windows 10.
