The range is 0.000000000sec (nano sec)

What Can I do ?

For example

Analog Ch AIN1   		 Voltage (V) -
Analog Ch AIN1   		 Samples -
Analog Ch AIN2   		 Voltage (V) -
Analog Ch AIN2

    Hello,

    The EVM does not support a time stamp feature. But this is can be implemented in the firmware you use for your design. The busy signal can be used, or the rising edge of the Convert start signals (note there are two convertstart on this device) to trigger a time stamp to be taken.

    Regards
