The data sheet seems to cover it. There is a throughput per channel limit and a limit on the number of channels available depending on mode, and a limit on the total output data rate. In the lower resolution modes, an internal 32 entry FIFO allows burst acquisitions up to 182 million per second.
At 10ps RMS resolution (70ps peak to peak), throughput is only 500 kHz per channel and 1 MHz for two channels with no burst capability so it is short on resolution and speed.
