* To maintain full 14-bit resolution may require a lower sample rate when sampling more than one channel per ADC.
** DAP 5400a maximum rate when sampling eight channels, one channel per ADC: 1250k samples per second per channel – 0.80 microsecond interval
*** DAP 5380a maximum rate when sampling eight channels, one channel per ADC: 625k samples per second per channel – 1.60 microseconds interval
*** Disk logging and data transfer rates vary with PC platform.
