Merlin II Protocol Analyzer User’s Manual CATC SW Version 2.50
1.2 General Description
The Merlin II Protocol Analyzer is designed as a stand-alone unit that can
be easily configured and controlled by a portable or desktop PC connected
via its USB port. Merlin II provides users with the familiar ‘CATC Trace’
user interface that is the de facto industry standard for documenting the
performance of high-speed serial protocols.
Merlin II supports the functionality required to analyze all levels, including
the baseband, of the Bluetooth wireless protocol. The featured Radio
Interface allows users to probe and analyze transactions at the lowest level
within the Bluetooth architecture. By creating this "Point of Observation" or
probing point within the radio level packet view, the user can analyze all
levels of the protocol stack.
Merlin II is a non-intrusive testing tool for Bluetooth piconets providing
network traffic capture and analysis. Hardware triggering allows real-time
events to be captured from a piconet. Hardware filtering allows the filtering
out of fields, packets, and errors from the recording. Filtering allows users
to focus recordings on events of interest and to preserve recording memory
so that the recording time can be extended.
Recorded data is presented in colored graphics in a trace viewer application.
This application has advanced search and viewing capabilities that allow the
user to quickly locate specific data, errors and other conditions, thereby
focussing the user’s attention on events of interest.
Merlin II functions with any personal computer using the Windows 98SE,
Windows 2000, Windows ME, or Windows XP operating systems and
equipped with a functional USB interface. For an updated set of system
requirements for the host machine, please refer to the readme file.
The Analyzer is configured and controlled through a personal computer
USB port. It can be used with portable computers for field service and
maintenance as well as with desktop units in a development environment.
The Analyzer is easily installed by connecting a cable between the
computer’s USB port and the Analyzer’s USB port.
Merlin II provides on-the-fly detection of and triggering on such events as
Packet Headers and Errors. Whether recording manually or with a specified
trigger condition, Merlin II continuously records the bus data in a
wrap-around fashion until manually stopped or until the Trigger Event is
detected and a specified post-Trigger amount of bus data is recorded.
Upon detection of a triggering event, the analyzer continues to record data
up to a point specified by the user. Real-time detection of events can be
individually enabled or disabled to allow triggering on events as they
