Option Digital inputs
This option allows the user to acquire additional digital channels synchronous and phasestable along with the analog data.
Therefore the analog data is filled up with the digital bits up to 16 Bit data width. This leads to a possibility of acquiring 4 additional digital
bits per channel with 12 bit resolution boards.
bits per channel with 12 bit resolution boards.
Sample format
The following table shows the sample format of the standard mode with the digital inputs disabled and the sample format with activated
digital inputs.

To enable the recording of the digital inputs you simply have to set the according register shown in the table below.
Due to technical issues there is a board dependant fixed delay between the analog and digital samples. The
delay for your type of board can be found in the technical data section.
