7.6 Sampling Functions
• Trigger reference value
The trigger reference value (trigger value) set with a word trigger sets the range corresponding to the size of each word
data.
• Filter specification
The trigger point is set as the point after time elapsed of the sampling interval filter specification value after the trigger
turns ON. The filter specification can be set for each channel.
■No trigger condition settings
No trigger conditions are set. Sampling can be completed with a STOP output during sampling.
Sampling points
The number of sampling points that can be set when specifying trigger condition settings is as follows. By increasing the
sampling points, the sampling results file size and time taken to output the results to the save destination increase, and
therefore caution is advised.

■Sampling points before trigger
