Hello,
I'm using Gnuradio 3.9 and UHD 4.1 with a N210 with only LFRX and LFTX.
I'm using USRP_source to receive samples, make some treatment in a
flowgraph and especially a decimation, and finally send the samples to
an USRP_Sink to get an analog signal resulting of my treatment.
My system is not perfect and a get some underrun sometimes. At each
underrun, the propagation delay is keep growing more and more. I can
measure that using an oscilloscope between input signal and output signal.
Why that propagation delay is always growing ?
Is there a way to reset the overall propagation delay at each underrun
that I could catch using PMT message in a C++ application ?
Thanks for your help,
Best regards,
Fabien, F4CTZ.
