hello everyone ,I want to use the fm_tx_2_daughters.py as a template to
realize my own module ,so I copy it to my own folder. but when I set
the interpolate to 64 and test the copy module ,“uU” appears.then I run
the usrp_benchmark_usb.py,the result shows “Max USB/USRP throughput =
32MB/sec”.I wonder why the “uU” appears. and i am sure my pc can keep up
with the speed ,as i have another module ,which is a one channel
receiver ,with the decim set to 8.and the program works well
