You did not present the configuration page of the UHD USRP block.
In any case, whenever a complaint refers to a frequency not being at or below half the sample rate, it means that the system thinks that you are attempting to either transmit or receive a signal at a frequency that is not below the Nyquist rate. The Nyquist rate is half the sampling frequency.
It is a fundamental law in digital signal processing that to either transmit or receive a pure tone intact (i.e. not shifting to/from baseband), the sampling rate must meet or exceed twice the frequency of the signal.

Can anybody guide me on this???.. I am using x310 with sampling rate of 1MHz.
Traceback (most recent call last):
