Pressing the Start button on the Operation Panel starts the Memory Recording. After the recording start,
the recorder is in the wait status for trigger detection. Pressing the Stop button stops the operation
forcibly. The following diagram explains the flow of operation.
(1) Data recording before trigger
After the memory recording start, trigger detection wait status starts. Memory block recording
continues until the trigger detection is made or the Stop button is pressed. When the trigger is
detected, data recording operation starts after the trigger. When the Stop button is pressed
and operation is forcibly terminated, the trigger recording is not made but the operation
judgment processing starts.
Other then trigger detection by an input signal, trigger detection can be made through the
NOTE
Manual Trigger or External Trigger signal. For details on trigger condition settings, see 13.
Trigger Setup.
If the Stop button is pressed and forcible termination is made before the trigger detection,
NOTE
data recording is made up to the size set by the pre-trigger. Example: Under pre-trigger
of 20 ms, if the recording is forcibly terminated before the trigger detection, the recording
length is up to 20 ms.
(2) Data recording after trigger
The amount of data specified by the pre-trigger is retained and recording for remaining amount
of data is made. The recording automatically ends but forcible termination is also made
through the Stop button. In this case, the data length will be shorter than the data length
displayed as recording time.
(3) Automatic judgment
When Auto Copy and Backup Filing are selected to be effective, automatic data output of
recording data is made. Memory block recording is repeated depending on the recording
operation.
If forcible termination is made with the Stop button, memory recording finishes without
NOTE
repeated endless operations.
If the block for overwriting is outputting data in endless manner, recording starts after the
NOTE
outputting is completed.
(4) Auto Copy
Auto Copy and Backup Filing are executed.
