System (UPAS). Together, the Analyzer and UPAS are controlled from a personal
computer USB port across a USB connection.
Figure 1.6 System Setup
USBTracer provides on-the-fly detection of, and triggering on, events such as Tokens and
Errors. Whether recording manually or with a specified trigger condition, USBTracer
continuously records the link data in a wrap-around fashion until manually stopped or until
the system detects a Trigger Event and records the specified post-trigger amount of link
data.
Upon detection of a triggering event, the Analyzer continues to record data up to a point
specified by the user. You can individually enable or disable real-time detection of events
to allow triggering on events as they happen, including predefined exception or error
conditions and user-defined sets of trigger events. An externally supplied signal can
trigger the Analyzer. An external DB-25 connector provides a path for externally supplied
data or timing data to be recorded along with traffic.
The DB-25 connector also provides a path for USBTracer to transmit externally the
software trigger signal or a user-defined event, for probing or use by other circuitry.
Search functions allow the software to identify and highlight specific events. In addition
to immediate analysis, you can print any part of the data. You can save the data on disk
for later viewing. You can generate timing information and data analysis reports.
