Explanation
Setting the delay time
The trigger delay time is the duration between the point at which a trigger is activated, and
the point at which data acquisition starts.

The setting range is 0 to 9.999 s. The setting step is as follows.

Points to note when setting the delay time
A delay time cannot be set if the external clock has been selected as the timebase. The
setting will be invalid if sampling is performed using the external clock.
