[Discuss-gnuradio] Configure UHD source and File sink to save integers

[mepard]

I'd like to feed a File Sink from a UHD Source with 4 channels -- 2 
motherboards, each with A:A A:B subdev specs. To cut down on the file size, I'd 
like to record integers instead of floating point. 

Which data type should I tell the UHD source to produce? Which type should I 
tell the File Sink to record? What conversions do I need in between? I'd like 
to stay in GRC, if possible.

TIA
