Thank you for your reply Eric.
I did print delta and delta.microseconds and guess what I did get this:
Receiver (0) = BABA0002
Requested RX Bitrate: 100k
Probe Level 39
0:00:00.000327 [*This is from printing delta*]
327 [*This is from printing delta.microseconds*]
Why do you think I should not get 309us? I am sorry if I don't get something
fundamental here. Thanks again for helping me out :)
No problem. 309us may be reasonable.
In general the wide variance that you're seeeing could be caused by
pretty much any other activity on the machine. You are measuring
Does this flowgraph have a USRP1? If so, the very long time could be
when you have first powered up the USRP1 and so it needs to have its
FPGA image downloaded.
