Bluetooth traffic. Shorter Bluetooth packets yield a less efficient recording.
The non-traffic portion of physical memory is utilized for control and timing
information.
Note The scale is not linear and affords more granularity in the smaller buffer sizes.
Trigger Position
The Trigger Position slide bar sets the amount of
post-trigger recording that Merlin will perform. It also
allows adjustment of the location of the trigger within
the defined buffer. You can adjust the Triggering
Position between 1 and 99% post-Trigger. Trigger
Position is available only when Manual Trigger or Event Trigger is
selected as Recording type.
As an example, if the buffer size is set to 16MB, then for the following
Trigger Position settings, the amount of pre- and post-Trigger data is
• 95% post-triggering: 0.8MB pre-trigger, 15.2MB post-trigger
• 75% post-triggering: 4MB pre-trigger, 12MB post-trigger
• 50% post-triggering: 8MB pre-trigger, 8MB post-trigger
• 25% post-triggering: 12MB pre-trigger, 4MB post-trigger
• 5% post-triggering: 15.2MB pre-trigger, 0.8MB post-trigger
Note When a Trigger occurs, recording continues until the post-Trigger amount of the
buffer is filled.
6.4 Recording Options - Piconet
The Recording Options dialog box has two pages for configuring how
Merlin records Bluetooth traffic: Piconet, which configures piconet
recording sessions, and Inquiry which configures inquiry recording
sessions.
