1.6 Advanced Event Counting and Sequencing
The count and sequence options define the rules for data recording sessions. These
options provide the ability to configure and control the order of events that have been
selected to trigger the USB2.0 Advisor Analyzer or filter the recording. There are two
counters and a restart option that causes the sequencing to start again.
By utilizing this feature a designer can specify a specific sequence of events that must
occur before the Analyzer triggers and finishes capturing data. This is extremely
important in allowing a designer to pinpoint certain types of events for recording. Without
this feature a designers must scroll through potentially megabytes of recorded data to
locate a specific sequence or occurrence of a sequence that can take hours to locate
before being able to begin analyzing the data of interest.
1.7 BusEngine Technology
LeCroy's BusEngine™ Technology is at the heart of the new Advisor USB 2.0 Analyzer.
The revolutionary BusEngine core uses state-of-the-art Electrically Programmable Logic
Device (EPLD) technology and incorporates both the real-time recording engine and the
configurable building blocks that implement data/state/error detection, triggering, capture
filtering, external signal monitoring and event counting & sequencing. And like the
flash-memory-based firmware that controls its operation, all BusEngine logic is fully field
upgradeable, using configuration files.
