Hello - I am using the USRP E312 and I am doing a 2 RX channel capture into the onboard 1GB RAM. Sample rate is set to 5Mhz. I am able to achieve capturing from both antennas at this sample rate but for some odd reason, I am not able to maintain consistent 5Mhz sample rate. i.e. The status w

Hi, We are using the B210 and the UHD library. We noticed that the function get_rx_gain() does not return the gain when the agc is enabled. To remedy this, one path forward is that we can write functions to do this if we can read/write access to the AD9361 registers. How does one gain access to t
