[Discuss-gnuradio] Same File Size

[Justin Bracken]

Hello All,

 

I am expecting to see a similiar file size in a simple test file that im running and I don't get that. Is there something Im missing?

 

USRP2->FileSink

SignalSource->Throttle->FileSink

 

I have checked obvious things. The USRP2 block is set to a decimation of 400. Given the 100MS/s rate of the USRP2 I expect the stream to be 250e3 MS/s. So I set the overall sample rate to 250e3. I have also set the datatypes of all the blocks to floats. The Throttle is set to 250e3.

 

If it matters the  signal source is set to a saw tooth,1Hz.

 

Im more interested in knowing that samples read back out of the files are synchronized. So I guess it doesn't matter if they are the same length if all this mean is that I need to trim the files to the same length.

 

Thanks,

Justin
