Merlin II Protocol Analyzer User’s Manual CATC SW Version 2.50
Sequence
The Sequence field presents a drop-down menu with choices for the
Hopping Sequence Standard:
• 79 Hops Standard - Sets the analyzer to track
regular piconet traffic with 79 channels
hopping scheme.
• Reduced Hop - Used for test-mode recording.
Restricts Merlin II to five hop frequencies defined in the test
mode specification of the Bluetooth Specification. When
Reduced Hop or Single Frequency is selected, the Sync method
is set to Test Mode and cannot be modified by the user.
A typical test-mode setup consists of a device under test (DUT)
and a tester. In this hop sequence the devices are set to hop on a
limited set of five frequencies. When recording in this mode, the
analyzer does not use any of the Synchronization methods and
the options under Synchronization become grayed out.
• Fixed Frequency - Allows the transmit and receive frequency
ranges to be specified. This mode is used for test mode recording
where the tester and DUT are transmitting and receiving on fixed
frequencies.
Enter values into the two text boxes to the set the transmit and
receive frequency ranges:
• DUT Xmit Freq, MHz (+2402) – Allows the setting of the
transmit signal for the Device Under Test
• DUT Recv Freq, MHz (+2404) – Allows the setting of the
receive signal for the Device Under Test
When Fixed Frequency is selected, the Sync method is set to
Test Mode and cannot be modified by the user.
Synchronization Method
Configures how the analyzer synchronizes to
the piconet under observation. There are three
methods of synchronization:
Sync and Record - Causes the analyzer to
perform a general inquiry, acquire the Master’s address and clock
information, and then begin recording.
