Thanks Eric, Juha, and Michael-
to get 3 helpful responses within an hour of sending a post is truly
amazing, particularly considering the time of the year.
I should have elaborated in my post. I tried the gr.head approach, but
I’m not sure it works in my application- I’m using the approach of the
astronomy guys, with a control button that turns on and off from
to a file descriptor. So if I use gr.head, correct me if I’m wrong, but
believe it immediately sends the number of samples specified to
I don’t think that way is compatible with the approach I’m using, which
ripped off from usrp_psr_receiver.py.
So you know what I’m doing, I’m using the USRP as a pseudo digital
oscilloscope with a capture to file option. When I see something I like
in the scope, I hit the “capture to file” button. It works great, but
currently I have to look at my watch to capture comparably sized
Perhaps there’s a way of incorporating a timed capture (or fixed number
samples to this model?
thanks again so much.
