Hello Alexander, in fact my question was only a theoretical one, because I read in the mailinglist about the ethernet connection and that 2 x 16Bit x 25MS/s = 800Mbit/s are used. Concerning my hardware setup I've to look tomorrow, because it's not actually my pc. Am 15.05.2011 um 16:07 schrie

Daniel, What hardware setup do you use to achieve 25MS/s? I wasn't able to get stable connection with more then 16MS/s, and even at 16MS/s I had drops. On Sun, May 15, 2011 at 17:04, Daniel Bartel wrote: > Hello, > > I was wondering about a little conflict concerning the sizes of the data > ty

Hello, I was wondering about a little conflict concerning the sizes of the data types in GNU Radio. The UHD driver sends 16 bits I, 16 bits Q samples over the ethernet interface at 25 MS/s and the return value of "gr.sizeof_gr_complex" is 8 bytes (64 bits). How does this actually work? I have
