Re: [Discuss-gnuradio] Recording samples for a predefined time

[Nate Temple]

Hi Ali,

One way to achieve this would be to use a "Head" block with the "Num Items" set 
to: samp_rate*2. 

Then set the values under the top_block/Options block to be: 

Generate Options: No GUI 
Run Options: Run to Completion. 

Regards,
Nate
