These numbers apply to continuous waveform generation, which allows for the time it takes to reset the FIFO to the
beginning when cycling through it. This additional time is not incurred when using host PC memory for waveform
generation. The max update rate in FIFO mode does not change regardless of the number of devices in the system.
