I am sending some AM modulated signal, Sampling Frequency: 200k at a center frequency of 2.41GHz since my laptop was not having inbuilt Gigabit Ethernet, hence I am using a USB 3.0 to GBe Ethernet convertor ( ASIX AX88179 ). I am able to ping and detect my usrp, but when I run a simple signal transmission code the the usrp halts after sometime ( the status led for transmission stops glowing ). I tried with different sampling rates but for sampling rates lower than 200k it gives warning of “UHD Warning: The hardware does not support the requested TX sample rate: Target sample rate: 0.020000 MSps Actual sample rate: 0.195312 MSps” and the same halting problem continues for higher sampling rates the warning disappears but the halting problem continues.
