Hi Marcus,
Thank you for support.
I tried to test TX and RX operation separately. I set USRP X410 as
receiver, it can works with sample rate more than 100Msps. But for TX
configuration, it can not handle more than 10Msps and I have several
U, underflow error.
While I am using both TX and RX configuration simultaneously it can
not go beyond 10Msps. BTW, here is my TX side code:
Signal_sourcce (Triangle)—->VCO(Complex)——>UHD/USRP_Sink
Any suggestion? Thank you.
Try using the "tx_waveforms" UHD example--it doesn't use Gnu Radio.
The signal-source block in Gnu Radio isn't particularly speedy, and Gnu
Radio in general requires more resources than
something that is carefully hand-coded. It's not bad, but at rates
like 100Msps, a hand-coded program will do better.
