  1. Mega Samples Per Second (MS/s) across all channels. Sum of sample rate of all channels must not be greater than 1 MS/s.
  2. See Analog Response Time App Note for details on time delay caused by analog filters.
  3. Time from executing writeDAC function to analog output starts changing.
  4. See Measuring Response Time for details on definition of latency and jitter.
