[Discuss-gnuradio] File sink question

[Ellie White]

Hello again,

 

I have a quick question to ask about how the file sink works (since this was slightly unrelated to the other question I thought I should put it under a different subject line). To provide some background info, my sampling rate is set at 300e6, and I recorded data for (I’m guessing) about 5 minutes. Based on some fiddling around in Python with a data file I saved from a file sink, it appears that just 426,152 time samples were recorded to file, so I am wondering, first, why are there so few samples recorded (i.e. why wasn’t the number of samples recorded 300e6*seconds)? And second, how does the file sink “decide” which samples to keep, and which not to keep?

 

Thank you in advance for any help/explanations!
