Hi Sneha - Please "reply all" to keep the discussion on the USRP users email list. More eyes reading these means a greater chance that folks will jump in to help!
The startup time for UHD / USRP / GR will be very similar between different runs of the exact same flowgraph, but not exactly the same. If you were to somehow measure these and plot them, I'd bet you'd get a curve that looks Gaussian except with limits (a "truncated normal distribution"). The exact same file being Tx'd over and again will have a slightly different delay on Tx each time. Not sure this is what you're experiencing. If you don't think it is, then please provide more information; what we have right now is pretty thin. Hope this is useful! - MLD On Thu, Aug 8, 2019, at 11:38 AM, Sneha vasan wrote: > Hi Michael, > > I sent a email before I confirmed the subscription for the usrp users.
