Activity in the Pre-trigger mode
In the Pre-trigger mode, data is read before the recording START. In the Record
Standby status, data begins to be stored in a buffer. This buffer stores the most
recent data for the specified period. At the recording START, the data for the
specified time before START becomes recorded data.
▼
Pre/Post Trigger
can be used in conjunction
with
Trigger Rec
, which is explained next.
▼
The possible pre-trigger time depends on the
amount of memory, the sampling frequency,
and the number of channels. Specify a value
that does not exceed the time possible using
available free memory.
▼
You cannot specify the time in seconds for
external sampling.
▼
The period between Rec Standby and Start
must be longer than the specified pre-time plus
one second.

Activity in the Post-trigger mode
In the Post-trigger mode, data is read from a specified time after START.
Example: If 5 seconds is specified for the post-
trigger, data is recorded from 5 seconds after
the time of START. However, when STOP
occurs within 5 seconds after START, data can-
not be recorded.
▼
During the specified post-time, the activity dis-
play shows “REC POST”, and the Rec Standby
button is disabled. Do not click the Stop button
during the post-time.
