Triggering Differences Between GPIB and LXI

LXI, introduced in September 2005, is the next generation test system architecture and will over time replace many of the existing GPIB-based systems. The LXI Consortium has taken great care in designing the triggering and synchronization functionality needed in future test scenarios. The paper will show the triggering and synchronization techniques used today in GPIB (like group execute trigger and SRQ); comparing them to similar and new techniques used in LXI (LXI events, LXI alarms, LXI trigger bus, peer-to-peer triggers, and multi-cast triggers). It will provide typical trigger examples and give code examples for the most common triggering and signaling techniques in LXI.
