Hi!

I am a student from China and I am studying the energy detection
algorithm
with USRP1 and RFX2400 on Gnuradio 3.3.0 and Ubuntu10.04. There is an
index
I want to know about the algorithm is Sensing Time including the
acquisition time of the samples the algorithm needs and the computing
time
of the samples on PC( I can get the computing time with PAPI to count
the
number of clocks of CPU).
So, I want to know the acquisition time of the samples which I think is
the
time from antenna to the daughter board and then to AD and to
FPGA(including DDC and CIC) and to PC in the end.

Can someone give me some advice?
And please forgive my poor English.
