6.6 Recording Options - Inquiry
The Inquiry page configures how Merlin II records Inquiry traffic. Two
main options are presented in the Sync Method drop-down menu: General
(Unlimited) Inquiry and Dedicated (Limited) Inquiry. These options tell
Merlin II what kind of Inquiry traffic it should expect to record.
This page includes settings only for Inquiry recording and BT
Neighborhood.
General (Unlimited)
Analyzer performs an Inquiry operation using the General/Unlimited
Inquiry Access Code, or GIAC (0x9E8B33). During the Inquiry period that
analyzer is recording all the FHS packets received in response until the
specified timeout is reached.
Dedicated (Limited)
Analyzer performs an Inquiry operation using the Limited Dedicated
Inquiry Access Code, or LIAC as set in the DIAC LAP field (the default is
0x9E8B00). During the inquiry period the analyzer is recording all the FHS
packets received in response until the specified timeout is reached.
Timeout (0-80 secs)
Default value for Inquiry Timeout is 11 seconds. A value of 0 sets the
Inquiry Timeout to "infinite inquiry."
Correlation Value (33-64)
This value tells Merlin II how many bits in the sync word of each received
packet must be matched in order for Merlin II to consider the packet valid
and start recording.
This value specifies how long Merlin II should perform the Inquiry process
for the General (unlimited) and Dedicated (limited) recording modes. After
the specified time has elapsed, Merlin II will illuminate the trigger light on
the front of the analyzer.
BT Neighborhood
These options configure how the BT Neighborhood command behaves. BT
Neighborhood is a utility that performs an Inquiry and then lists the local
devices that it discovered.
• Use Default settings -- Sets the analyzer to record a General
Inquiry with an Inquiry Timeout of 11 seconds.
• Match 'Inquiry' Recording Settings -- Sets the analyzer to use
the settings you chose above under Hop Sequence, Inquiry Type,
