Thanks for the response Ian, with packed you mean that when using the SC16, it also uses all of its bits? Considering the IC appears to always return 12 bits per sample, couldn't the FPGA increase the number of bits even further for higher dynamic range? I'm thinking maybe sampling at high an On

Miguel, By default UHD will always move samples to/from the B200 over USB in the so called SC16 format, which is a fixed point point representation with 1 sign bit and 15 fractional bits (-1<=x<1). You can also use SC12 and SC8, which have respectively 1 sign bit and 11/7 fractional bits if you

Hello, I got a B200 and I'm wondering if data is sent with "unsed" bits when sending data from the sdr to the host. For instance in case of 12 bits per sample, would those 12 bits be sent in a 16 bit block? If that's the case, is there any reason not to transfer data more efficiently (specially
