Match Clock Rate
Match Clock Rate is a useful option if the Master device’s clock is
inaccurate. Match Clock Rate causes Merlin II to do a General Inquiry to
determine the Page Target's clock rate prior to synchronizing to the piconet.
If unchecked, Merlin II will begin piconet synchronization without first
doing a General Inquiry.
This option only works with Page Sync and Record mode.
Timeout (0-80 secs)
Default value for Inquiry Timeout is 20 seconds.
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.
Initial De-whitening State
De-Whiten On -- Turns on De-Whitening
De-Whiten Off -- Turns off De-Whitening
This setting controls the initial de-whitening state.
If " De-Whitening Off" is selected, Merlin II will try to synchronize without
de-whitening the received packets, and assume that they were transmitted
un-whitened.
If " De-Whitening On" is selected, Merlin II will use received packets to try
to synchronize while it is performing a de-whitening process that complies
with Bluetooth specifications.
This setting controls the initial state for the synchronization. After Merlin
II has synchronized to the piconet, it will try to follow changes in the
whitening scheme and dynamically track whitened and non-whitened
traffic.
In case a recording was stopped and you want to restart a recording session
of the same piconet, you should remember that Merlin II might still be
synchronized to the same piconet. As Merlin II dynamically follows
whitening scheme changes, it will not use the initial de-whitening state.
However, if you want to force an initial de-whitening state, check the "Force
Re-Synchronization" flag.
