Hi... I mean... the sampling rate of the uhd sink and source what refers to...? I've since in some documents that if you are transmitting , you have to take in account that the DAC for output works at 128 M/s and the sample rate for the UHD sink block has to be determined somewhow from that.
In the same way the ADC for reception works at 64 M/s and the sampling rate for the UHD source block has to be determined somehow from that 64 M/s . I just want to make simple transmission and reception. Am I wrong? or I am understanding not really good what I am reading about this. Thanks in advance.
