Sampling speed (milliseconds)
*1
Trigger logging interval (seconds)
*2*3
File save time (seconds)
*1 The maximum time before/after the trigger where data can be retained and output to a file when a trigger occurs.
*2 The time required to output 100 lines (records) of data before/after the trigger.
*3 If the file switching and folder switching have occurred, the file save time will be longer by one second.

NZ1MEM-16GBSD
Data is sampled for each scan and the sequence scan time which can perform
trigger logging is measured.
The time taken from when data corresponding to the number of lines before
and after trigger has been sampled up to when saving it to a file is completed
is measured.
