[0] : 2 x HD68 connector - 32 channels per connector, fits differential pairs on twisted ribbon.
[1] : Typical values measured at full scale with a 10kHz input.
[2] : via post processing numerical adjust using onboard calibration table
[3] : accuracy may be exceeded by either controlling temperature or compensating for temperature.
Card is fitted with temperature sensing to facilitate.
[4] : factory fit option
[5] : 14 bit resolution with no oversampling, 16X oversampling can raise the resolution to 16 bit effective.
[6] : Other multi-rate options possible
