I am running basically the code sent by Chris S.,
This code has two threads: one that reads data from the USRP and another
thread that writes to file. I have modified it so that I write to memory
during a predefined time and then save to file. I am also using two
instead of one.
I am using only basic RX boards and have connected a signal generator to
of the four A/D inputs which sends a sinusoid of 399kHz. When I segment
data in 1000samples long segments and do SINAD analysis per segment the
value is good in most segments except at regular intervals. It seems
sometime looses a complete buffer.
I doesn’t seem to help to increase the decimation factor.
I am using windows XP with cygwin - is this the problem ?
Any help would be appreciated!
