Note 1: The same applies to both software and hardware triggers.
Note 2: Only during scan operation, execution time per channel is added.
(2) Calculating the conversion time when sample-and-hold is enabled
The following schematically shows the method for calculating the conversion time when the sample-and-hold
function is enabled.
