[0] : 2 x HD68 connector - 16 channels per connector, alternate signal pair and ground for improved crosstalk.
Also available with LFP on special order
[1] : Typical values measured at full scale with a 1MHz input.
[2] : 14 bit resolution with no oversampling, 16X oversampling can raise the resolution to 16 bit effective.
[3] : via post processing numerical adjust using onboard calibration table
[4] : AAF factory build options, 4 pole filter with cut-off at either on 2.5, 5.0, 10, 20 MHz
[5] : Other multi-rate options possible
[6] : Factory fit ±2.5V option
