Merlin Mobile User’s Manual CATC SW Version 2.0
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.
Options
The Options box contains two options:
Beep When Trigger Occurs
Will cause the PC to beep when a trigger event
has occurred.
Save External Interface Signals
Will enable Merlin Mobile to record input signals from a breakout board as
fields in a trace.
Buffer Size
The Buffer Size box has a slide bar for adjusting the
recording buffer size from 0.4 megabytes to 512
megabytes.
