To achieve 50Msps, you'll need to use 8-bit wire format, and set the peak= parameter appropriately. There's just not enough bits/second on a 1GiGe link to support 50Msps with 16-bit, full-width samples. But you also need to consider the format you're writing samples to disk in, and how much disk-write bandwidth you'll require to support that. If you just use the same format (2 x 8bits) into the file, that's 100Mbyte/second into the disk. That may or may not be supportable on your particular system. |
