Recording When Already Synchronized

If the analyzer were already synchronized to a piconet, it will not try to
re-synchronize to the piconet that is defined in the Recording Options.
Instead, it will immediately start the recording using the frequency hop
sequence from the last recording operation. This results in shorter response
time until the actual recording is started.

The analyzer will attempt to synchronize only in the following:

• The hopping sequence setting was modified from the last

recording.

• The 'Force Re-Synchronization' flag is checked.

Master and Page Target Menus

To the right of the Sync Method menu are two menus which let you select
or enter address for the devices in the piconet:

Master Address - Presents a drop-down list of Master devices

found previously. It also displays an option called Any which is
used in Page Sync and Record to tell the analyzer to synchronize
with any Master responding to the specified Page Target/Slave
address.

Page Target -- Presents a drop-down list of Page Target devices

found previously. You can also enter address values in this box.

Between the two text boxes is the following button:

- Swaps the Master and Page Target addresses.

When to Use the Different Piconet Recording Modes

Page Sync & Record is the preferred option and should be used whenever
possible. If Page Sync & Record can not be used, then Sync & Record
should be used. Passive Sync and Record should be used only if the first
two options can not be used.

Sync & Record

Sync and Record works just like "Page Sync and Record" except that Merlin
II takes its sync data directly from the Master instead of the Slave devices.
With Sync and Record, Merlin II conducts a General Inquiry to get hop
frequency and clock information from the Master. Merlin II then waits to
detect piconet traffic from the Master device’s piconet. When the piconet is
established, Merlin II is able to synchronize to the Master and begin
recording. In contrast to "Page Sync and Record", "Sync and Record" can
be run with or without an established piconet.
