E Series User Manual
You cannot disable dither on the NI 6011E (NI PCI-MIO-16XE-50). The
ADC resolution on this device is so fine that the ADC and the PGIA
inherently produce almost 0.5 LSB
equivalent to having a dither circuit that is always enabled.
Figure A-1 shows a block diagram of the NI 6011E
(NI PCI-MIO-16XE-50).
