The CATC Inspector analyzer has two basic recording modes, timed and event driven. Both may
be used with external triggering. With timed recording, the analyzer can be set to start or stop
recording based on its EXT TRG (input) signal. This mode of operation is the same as the CATC
Detective USB Bus & Protocol Analyzer.
With the event driven mode of operation, it is possible to combine other triggering events with
the EXT TRG signal. For example, if some external device (such as a logic analyzer) is set up to
trigger the CATC Inspector tool, it is still possible to enable USB error checks or PID checks as
well. In this situation the first detected event, internal or external, will trigger the analyzer.
