Jose,

If you set your file source to "repeat" it will produce an infinite amount of samples, just like a sine would. If you know you want to produce 10,000 packets (and see how many are received), you only need to 96*10,000 samples. Hence, you'll use the head block after the file source and set it to 960,000.

Best regards,
Marcus

Thanks again Marcus.

Now I am using the "Head" block... I don't know which number I have to put
in "Num Items" to get out my file with no repeated information.
I can understand this number to a Sin/Cosine function or a random source
that I can limit how many samples I want ... but for a file I don't know and
how calculate this number.
Can you help me with this?

My size's file: 120 bytes ; packet length: 96

Thanks so much

Cheers,
José

As I mentioned, use the "head" block.
