7.1 Recording Options - General
The General tab opens a window shown in the previous illustration made up
of four boxes marked Recording Type, Buffer Size, Trigger Position, and
Options.
Recording type
The Recording Type box presents three options that
allow you to set how Merlin begins and ends a recording.
The options are: Snapshot, Manual Trigger, and Event
Trigger.
Snapshot
A Snapshot is a fixed-length recording whose size is determined by the
"Buffer Size" box in the Recording Options dialog or by a manual click of
the Stop button. Recording begins by clicking on the Tool Bar and ends
when either the selected buffer size is filled or you press the Stop button.
Manual Trigger
A Manual Trigger recording is a one that is manually begun and ended.
Recording is begun by pressing on the Tool Bar. Recording continues
in a circular manner within the limits set by the buffer size. Recording ends
when is clicked on the Tool Bar or the Trigger button is pressed on the
analyzer's front panel. If you press the Trigger button, recording will
continue until the post-trigger memory has been filled.
Event Trigger
An Event Trigger recording is one that uses an event trigger to end the
recording. Before recording begins, you define the event trigger in the
Trigger Options dialog box. You begin the recording by clicking on
the Tool Bar. Recording continues in a circular manner within the limits set
by the buffer size. Once the trigger event occurs, some post-trigger
recording occurs, then the recording ends.
Note In this mode, the recording can be stopped manually in the same way as for
"manual trigger" mode.
