Hello all,
I have been trying to perform ranging between nodes using time-of-arrival of signals. To this end, I am trying to transmit an accurately timed pulse using the USRP. My initial experiment simply sends out a 100 ms burst every 1 sec. I am then recording this signal using NI PXIe-5663 front end for analysis. Everything is working out fine, except that I am seeing some wild transients at the beginning of the burst for several nanoseconds.
I am attaching some plots that show this behavior at

Is this the reason I am seeing these transients? Is there anything I could do to correct this?
Thanks,
Lakshay.
