Chapter 2: General Description
USBMobileHS provides on-the-fly detection of and triggering on such events as specific
user-defined bus conditions, packets matching any Packet Identifier (PID), packets
matching a Token or Setup transaction, data patterns, and errors and bus conditions.
Whether recording manually or with a specified Trigger condition, USBMobileHS
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 happen. This includes predefined exception
or error conditions and a user-defined set of Trigger events.
The USBMobileHS software provides powerful search functions that enable investigation
of particular bus 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.
