user-defined set of trigger events. The unit can also be triggered by an
externally supplied signal. An external DB-9 connector provides a path for
externally supplied data or timing data to be recorded along with bus traffic.
This DB-9 connector also provides a path for Merlin to transmit externally
two control, timing, or recovered signals for purposes of probing and use by
other circuitry.
The Merlin software provides powerful search functions that enable
investigation of particular events and allow the software to identify and
highlight specific events. In addition to immediate analysis, you can print
any part of the data. Use the Save As feature to save the data on disk for later
viewing. The program also provides a variety of timing information and
data analysis reports.
1.3 Automation
The Merlin software includes an Application Program Interface (API) for
developing testing programs and scripts in C++ and Visual Basic. The API
reproduces most of the commands embodied in the Merlin trace viewer
software. This API allows users to automate procedures that otherwise have
to be run manually via the trace viewer software. The Automation API can
be run locally on the PC attached to Merlin or remotely over a network
connection.
For further details, refer to the Automation API for CATC Bluetooth
Analyzers reference manual included in the installation CD-ROM. You can
also download the document from the CATC website.
1.4 HCI Trace
In addition to the ability to record Bluetooth traffic off-the-air, using the
analyzer's hardware and radio module, the Merlin can record serial
Bluetooth HCI traffic from Bluetooth devices, or 'IUT's (Implementations
Under Test).
While the off-the-air traffic is captured by the analyzers hardware, the HCI
Traffic from the IUTs is captured by the analyzer application using an HCI
probe (provided by CATC) that is connected directly to the IUT hardware.
In a typical setup, the HCI commands and data to transmit are passed from
the Bluetooth application to the Bluetooth baseband (Host to Controller),
while events and data that was received are passed from the Bluetooth
baseband to the Bluetooth application (Controller to Host).
