The maximum number of

sample data when a timer

is the sampling trigger is

calculated using the

following formula:

120000⫼[Number of

Channels Used]

The maximum number of

sample data when an

external trigger is the

clock source is calculated

using the following

formula:

120000⫼([Number of

Channels Used] + 1)
